 This review is for the Fullspeed Toothpick Pro, the more robust 4s-capable micro quadcopter made by Full Speed RC. It is available from the following retailers that will ship internationally with options for FRSKY, Flysky, Spectrum and now TBS Crossfire as well:
If you are looking for the the standard 2-3s Fullspeed toothpick, the full review of that can be found here and is available below: Fullspeed RC were the first to market with a bind and fly quad inspired by Bob Roogi's "toothpick"design - an ultralightweight quad based on small motors and 65mm props suitable for park flying. This was a very good park flyer - quiet and well built with good performance on 2s or 3s. It does have a full micro camera and VTX meaning it has a very nice FPV feed but is slightly on the heavy side. This model has obvioulsly been successful for them so they have quickly followed up with the Fullspeed Toothpick PRO. Specs compared with the standard toothpick below which I will discuss further:

 This is a review for the Fullspeed Toothpick, an ultralight fully featured micro quadcopter that is 2s and 3s capable. It is available from the following retailers: Introduction The toothpick is the latest release from Fullspeed, the company that bought you the Leader 120, the Leader 2.5 and 3.0 as well as the Tiny Leader. In a departure from the naming system their newest micro qudcopter is called the FullSpeed toothpick as a nod to the motor/prop combination that has been extensively test by Bob @ kababfpv.com (with his blessing). The outcome of using this mix of components is meant to be efficiency, control, surprisingly good power and safety. More on this in the review that follows.
Component overview I'll give my quick thoughts on the components below and will point something unique out with this build compared to others in the class - it has indivual components rather that a range of all in one gear we've become so familiar with on the Mobula7, Tinyhawk, Trashcan and even the new Sailfly-X. This means you can replace or upgrade component by component as required.
 Introduction
The Fullspeed Tiny Leader is a new sub-micro class quadcopter from FullSpeedRC.com that is ducted and competes in the now popular and increasingly competitive brushless whoop market. Full Speed is a now well known and respected producer of micro brushless quadcopters including the original Leader 120 (review here) and more recent Leader 2.5 (review here) and Leader 3 (review here). Below I will outline the published specs and what sets this apart from other brushless whoops - good, bad or indifferent. To clarify there are 2 current Full Speed Tiny Leader models: The TinyLeader Regular and TinyLeader HD with onboard HD recording. This review is for the TinyLeader regular  The Leader 2.5 is a recent release from FullspeedRC and as well as being available on their own website, is also available from Banggood and Gearbest. If you do decide to purchase, Fullspeed over many more customisations and offer free shipping till Jan 2019. The Leader 2.5 follows the recent Leader 3 but is limited to 2.5 inch rather than 3 inch propellers. My objective for this blog is not to write a tradtional review due to the similarities to the Leader 3 but to cover the keys settings and physical changes I'd strongly recommend to enjoy this quadcopter.
If you haven't yet seen the first part of my Leader 3 (SE) review, click here. In it I cover an overview of the New Leader 3 including full discussion of the components, build and software setup. A quick correction too: I mentioned originally that the flight controller (namely the gyro) will only do 8kHz loop times. This is incorrect - it will actually run up to 32kHz! Certainly the first I'm aware of on a board this size and something for me to test in future.  Before I go any further I should note that my Leader 3 is a review model and so there may be minor improvements in the final version shipped to buyers. I'm in regular contact with Full Speed RC to give them feedback on what I find to assist with these improvements. The Leader 3 is available directly from FullSpeedRC.com, Gearbest or Bangood. Video performance Since FPV performance is common between 3s and 4s I thought I'd cover that first. In short it is outstanding. Fullspeed RC shared a lot of the development of the included TX600 vtx with me an a lot of effort went in to ensuring a clean video signal all the way up to 600mW and the results sure doesn't disappoint. The result is that the Leader 3 has the cleanest video signal I have every used. There is absolutely no impact of throttle or other electrical noise on signal and it is hard to put in words just how much more enjoyable this makes the signal. I do miss the audio that AKK VTXs allow for but most people don't rate this as being important, especially on a micro. It's noteworthy that the the transmission power will go as high as 600mW - equalled only by the AKK FX3 ultimate (review here) in this form factor. OSD control of settings via Tramp works as expected. Antenna connection is via UFL is common for micros and fit for purpose. No propellers in FPV view Great news for those who don not like seeing their propellers - the frame design means that even with fairly modest camera angles of around 35°and up there are no props in view. Hopefully this is clear from my videos below. This also make the drums for a Caddx Turtles HD camera install beat even louder... Camera Angle I wanted to clear things up on camera angle since Nick Burns mentioned it couldn't go past about 45° in his otherwise excellent review. I can confirm that the camera connector does not foul on the flight stack and does infact smoothly go all the way up to about 90° amgle. Pictures are best here so please see below:
Performance on 3s When the Leader 3 was shipped to me, 2 custom PID prodiles were programmed in by fullspeed, Profile 1 was designed for 3s and profile 2 for 4s. 3s was tested with profile 2. Both of these profiles can be seen in full in part 1 of the review here. For 3s testing I used Turnigy Nanotech 3s 450mah 65c batteries. They weigh less than 45g meaning all up weight was around 140g. Flight time using these batteries was typically around 2.5-3 minutes with batteries coming to a resting voltage of arounf 3.75v per cell. Flying exclusively with the HQ 3x3x3 propellers flight felt very 'balanced' - what I mean by that is the quad didn't feel overly heavy (or light), top speed was fast enough but not ludicrously fast like the Skystars Bolt X120 on 4s (review here). It was however very predictable - I could hit gaps and avoid obstacles in a way where I felt I had complete control. It was fairly similar to the way the Emax Babyhawk R 3 inch felt (review here) but the HQ props felt more predictable and familar compared to the EMAX Avans. This makes sense - both the Leader 3 and Babyhawk R are of similar weight and with 1106 4500kV motors on 3 inch props and both have optimised PID tunes. Full Speed RC seem to have done a good job on the tune here not just for the feel during flying but also in keeping propwash to a minimum, even when I tried to put myself in dirty air in 180° turns or descending directly down. Below is a video from an early flight (2nd pack ever) in a local carpark. Typical I had DVR issues in a flight later that day where I'd gotten more familiar with the flight characteristics :/ Performance on 4s The battery I used for all 4s testing was the China Hobbyline Ministar 4s 650mah pack. It is an excellent battery that I even use on my 4 inch racer so is very capable although a little heavy at 87g. First of all I'm going to talk about straight up speed and my perception. It did not feel as fast as the Skystars Bolt X120 using the same battery. This is not an objective measure, purely feel. It did feel faster than the Babyhawk R 3" using the same battery. To dig in to this further though I do need to say that that Skystars Bolt X120 is very hard to control with this battery and I did not enjoy flying it because it felt difficult to control. It felt like it needed more open space which then kinda defeats the purpose of a micro. By comparison the Leader 3 felt in complete control using 4s and PID profile 2 as customised for 4s by Full Speed RC. As a result it felt right at home on 4s with all the control and balance I felt on 3s. I think part of this is due to tune but moreso that that larger 3 inch blade is able to better support the additional weight from the heavier pack and hasn't overloaded the propeller (disc loading theory). All other features of flight were similar to 3s - excellent video, precise handling and minimised propwash. I was really enjoying flying this until... Disaster Struck! When I first received this model, Full Speed RC cautioned me to use 4s using the smaller Gemfan 2540 props (review here) since motors could overheat. Since I was the only reviewer to receive mine where it is winter presently rather than summer, this was less of an issue although I did keep an eye on motor temps. For this reason I stuck with the included 3 inch props for 4s. About 10 packs in of warm motors (40-50°C only) I fell out of the sky when attempting a short speed run (see video below). On closer inspection the left rear corner had failed that I could later confirm as a motor failure (as opposed to ESC). The motor definitely was warm only as above and not hot. The only other time I've had a motor failure was on the babyhawk r when I used PIDs with too much P and D on 4s and even then the motor did not fail mid flight, rather afterwards intsead. This motor was scorching hot. I discussed this with Full Speed RC and found that they will be using a stronger motor on the production version - the review version like I have are a prototype. As you can see below when comparing to my burnt out motor on the Emax Babyhawk R, the Fullspeed one does not look nearly as abused - it failed at a much lower load. Interestingly shortly after this I saw Andy RC's review and found he had an identical problem - motor failed mid run using 4s with HQ 3x3x3 props. Update: The prototype motors are actually 4800-4900kV and the production version will be 4500kV.
So, what does this mean for you? Until I can confirm that Fullspeed RC have moved away from the proptotype motors I can't recommend using the HQ 3x3x3 props with 4s, even in cold weather. For now stick with Gemfan 2540 props on 4s. Of course if it ships with new motors then all bets are off. Full Speed RC is sending me a full set of new motors so I will test with these and post my results in a follow up review as soon as I am able. Update: The prototype motors are actually 4800-4900kV and the production version will be 4500kV. Conclusion The Full Speed RC Leader 3 is as an excellent flyer on 3s - great video signal and predictable handling make for an enjoyable flying experience. On 4s the Jury is out... custom pids make this fly well too but the motors' inability to cope with the included 3" props are a bit disappointing. For now a bandaid solution is to run with Genfan 2540 props on 4s but I expect that Full Speed will release with a stronger motor for launch as they did with the original Leader 120. Again, my sample is a reviewer model and this feedback is used to make changes if needed to the final launch product. Full Speed RC has proven themselves to be a reputable company with well researched (and tested) quadcopters and I expect them to follow through on this model too. The Leader 3 can be purchased directly from FullSpeedRC.com - their shipping is a little more expensive ($8) but is the fastest. Alternatively you can now purchase at Gearbest (standard version) or Banggood (standard or special edition) or Hobbycool (special edition)
 The Leader 3 SE from fullspeedrc.com Introduction The Leader 3 (SE) is a follow up to the hugely successful Leader 120 which I have reviewed and documented modification extensively, most recently with a summary here. Both are available from Fullspeedrc.com This has been a highly anticipated release not least of which because there has been no releases from Full Speed since last years' Beebee 66 light. The good news is that a big chunk of that wait has been spent working on the Leader 3. FYI two of the main guys are pilots from Full Speed RC are pilots and do a lot of work testing before release which is a welcome change in this hobby compared to many models that come out half-baked. Firstly the Leader is available in 2 variants. The standard model (Leader 3) can be seen below and weighs 87g with regualar standoffs. The Leader 3 SE is exclusive to Fullspeedrc.com and comes with a 3d printed canopy instead of the standoffs. It is 6g heavier but offers several benefits that I'll cover a little later on. A run through the components First the frame. Like the Leader 120 the base plate of the frame is 3mm thick although it has been stretched to 130mm motor to motor diagonally rather than 120mm This means it is capable of accepting a true 3" propeller rather than 2.8" maximum on the Leader 120. The frame is most definitely still a 'deadcat' shape meaning the two motors are further apart (107mm) than the 2 rear motors (98mm). Additionally it is a 'squashed-x' compared to a 'stretched-x' meaning the front and rear motors on the same side are closer together. This means it should be more stable in the roll vs. pitch axis but modern flight software somewhat negates this. Compared to the leader 120, sideplates have increased from 2mm to 3mm thick which should aid durability. More imporatantly a 19mm gap rather than 17-18mm means the leader 3/SE now natively fits a 19mm micro cam. It's worth nothing that the baseplate is only 1 piece so you cannot replace single arms. Personally I think replaceable arms are unnecessary on any quad size less than 4" since there is much less leverage for breaking on a smaller quad. The frame can be purchased separately here.
The canopy (Leader 3SE only). When I first saw the canopy I wasn't keen because it adds 8g weight however I think the functionality may just offset that - jury is out until I fly it some more. The 3d TPU print is of very high quality available in black,white, red, purple, blue or yellow and performs the following functions:
The motors are 1106 4500kv which is the same specs as those found on the Emax Babyhawk R 3 inch and the Skystars X120. They are not open bottom and have mounting holes for regular t-mount props and the emax 2.3" avan props. Most importantly they are rated for up to 4s.
The Build Like the original Leader 120, build quailty is excellent. Solder is clean, wires are cut to length. Not much more to say here, it is well beyond my ability! With the quad assembled there is plenty of room behind the camera to adjust tilt (45° and beyond are capable) and the receiver is mounted in this void. with plenty of room left yet. This is speculation but I'd like to address anyway since it seems like a common thread: my best guess is the caddx turtles HD FPV/DVR (not yet released at time of writing) will fit but not without a little modification. My reasoning is that there seems to be 2-3mm 'spare' room between each stack layer. If these standoffs are trimmed by this amount you will be able to save 6-9mm in height which should be enought to fit the turtles board. It will require some fine wire management and a steady hand to trim the standoff but I do think it may be physically possible - a project for another day. That being said, the double stack of the runcam split micro definitely will not fit.
Software setup Plenty to talk about here although most can be foundin commentary of the Betaflight screens below. If you don't choose to read these however:
Final thoughts pre-flight As you can see from above this looks to be a very well thought out quad and not something slapped together from a spare parts bin. The Babyhawk R and Skystars bolt X120 have both shown that 1106 4500kV motors perform well on 4s in 2.5" and 3" so I am excited to see what the Leader 3SE will add here with all the work that has gone into development from a hardware and software perspective. On paper this looks to have the edge on both of those models in terms of weight, VTX capability and ESC current overhead however the real test will come in flight - stay tuned for part 2 of this review where I will cover flight in full - I already have 3s and 4s batteries charged for tomorrow :)  The Fullspeed RC Leader 3/SE can be bought directly from Fullspeedrc.com and is also available at other retailers however buying from the source is your best chance to get your hands on one quickly.

 The Beebee 66 is a micro 1s brushless powered quadcopter which is essentially a brushless Tiny Whoop. It is made by Full Speed RC, the same company that produced the highly successful Leader 120. (review here). Gearbest kindly supplied me a BNF Beebee 66 to review. I was desperately hoping for this to be the brushless answer to the tiny whoop but I'm really bummed out that it just isn't. Read on to find out why. Adding a receiver Since this was supplied as a BNF model, it came without a receiver. I opted to use the lightest FRSKY receiver I had on hand - an XM that I'd finally figured out how to fash with the RSSI channel 16 firmware. In most models this is a matter of soldering wires to the exposed pads on the top of the flight controller. However,since the FC and ESC are part of the structure of this quad AND the FC is flipped upside down to sit the ESC connector in a manageable location, the prop gaurd, 4 nylon nuts and the flight controller itself had to be removed before I could access the receiver solder pads. Then I needed the help of a multimeter to figure out ground, +5v and signal wires. Once soldered up with a short length of silicon wire to the receiver it was easy enough to re-assemble and tuck the XM reciever underneath the canopy behind the AIO camera/VTX. Pics below of course can explain this better:
It's not the end of the world wiring in a reciever here but can be fiddly with particularly small hardware. I'd recommend if you did buy this model that you purchase with the receiver of your choice pre-fitted. Betaflight Setup Kept it pretty simple here. Because this is quite a different steup than I am used to I retained the stock settings on Betaflight 3.1.7 that it arrived with. All I did was set an arm switch and a mode switch for angle-horizon-air. Below are the default settings from Betaflight 3.1.7. Oh yeah, receiver had to be set up too. Like most f3 boards receiver is on UART 3. Quad Prep The only other preparation was pretty straighforward. The included GNB High Voltage 1s 260mah Lipo battery was easily charged using the included USB adaptor and a micro usb cable I had on hand. Only 1 set of props was included that are press-fitted on the tiny 0705 fullspeed branded (Sunny Sky made) 0705 brushless motors. I left the VTX on the default channel for the initial flight that my Aomway Commanders (review here) picked up as 5905MHz. First flight Please look away if you love your Beebee 66 because it starts to get a bit ugly here. After fully charging the LiHV batteryand confirming everything was working ok I armed and found the props were fouling on the TPU canopy. Minor annoyance down to the tight tolerance in the slightly flexible TPU canopy. Easy enough to bend out of the way and I was back in action. The first thing I noticed how loud the motors are - not in idle where they are practically silent but under any sort of load. Next as part of test with line of sight attempting a 'punchout' I could clearly see the quad dipping (pitch/roll) and twisting (yaw) under load. I'll attempt to tune this out later on and will post another review if successful. Moving on to line of sight I found the flight performance dull and uninspiring. What's worse was that after just one and a half minutes flight my battery was sagging down below 2.7v - the motors were clearly very demanding for their relatively mild output. I really wanted this quad to be a success and in fairness there is a chance I could have a less than perfect unit but my experience is my experience and I was disappointed. I do have some thoughts on how to improve though and I'll cover this in my Next Steps section below. Comparison to a brushed micro Please understand that these comments aren't made from isolation - I've had some experience with tiny whoops based on 7mm motors (like the JJRC H67 or Eachine E011) and although these are cheap brushed toy grade quads, they offered equivalent or better power and a flight time of 4 minutes plus on the same size battery with much smoother flight performance. A quick note that I actually tried the stock battery from the JJRC H67 (260mah non-HV) and got only 1 minute flight before it sagged below 2.7v under load. After recovery it bounced back to 3.65V but this same battery give my 4 minutes plus in my E011 FPV or santa whoop. Recommendations At this point I can't recommend this quad. The performance I experienced was poor and the flight time was unacceptable. My guess it that the brushless motors do not scale down well to 7mm, at this size the brushed motors seem to be more approprate. I'd recommend going in one of two directions:
Next Steps I'm not content to leave things be with the Beebee 66 and the latest version of this model (Beebee 66 lite) has shown the direction I want to go in - removing weight. I'm skeptical of getting to the level of improvement I want but with some of the parts below I think I can replace the canopy with a simple camera holder. remove the propgaurd and TPU supports and save up to about 4g. Will this make enough difference? Not sure but will report back when I'm done. Make sure you bug me about the follow up in the comments if I'm too slow! Below are some of the weights of the components I'm interested in: This is part 2 of my review of the Leader 120 by Full Speed from Gearbest. For part 1 click here. As at September 2017 try code HarvestRCnew7 to get this for only $US93.99!  None of the dreaded "brown outs" here Straight up I have had none of the reported issues of brownouts as many of the youtube reviewers found on the first version of the Leader 120. In saying that my review modelis version 2 which I has the fullspeed branded black motors. The default idle speed of which there was a lot of chatter about was set at 10% from the factory in Betaflight 3.1.7. This is very high and reducing it to my regular 3.5% caused no issues. So on to the more interesting stuff! Flight characteristics This is a great little flier, As I expected from hearing the motors run in betaflight they are very quiet and coupled with the well-balanced KK 2840 props it lets off very little noise in flight. Coupled with the size, this makes it much more socially acceptable to be flying in areas that aren't completed isolated. The rates are not stock either and I actually really liked them, even compared to my stock betaflight 3.2.0 settings when I flew my 5" quad immediately afterwards. There are an awful lot of micros that have poor or no tuning from the factory so was escpecially pleased when the tuning here required practically nothing for those either lacking the know-how or too lazy to do. Power is excellent on 2s and comparable to many 2" quads on the 3s - the bigger props and relatively light weight really make these motors come alive. Handling was predicatable and I felt I had good control even in heavy gusts.  Stock battery The stock battery can be described as adequate. I can see the voltage alarms were set low at 3.0 warning, 2.9 critical to allow for the sag but it keeps you in the air with moderate flying for up to 4 minutes. Considering I was able to flow without esc desync, losing vtx signal or getting failsafe, this probably makes it better than 90% of included batteries out there (not kidding). I'll have a follow up tips and tricks article soon where I look at some of the other internationally available battery options including 3s. FPV - Camera and VTX Ahh a chink in the armour. Hitting a sharp price point eventually means compromise and I think I've found it. Typical of All In One (AIO) cameras this handled low light on a dull day poorly even with the focus correct. Kind of makes branches jump out at you when flying under trees - that's my excuse anyway. Secondly although the VTX does well enough for 25mW, it still only does 25mW. That means that I started seeing breakup at 100-150M away or as soon as I was on the wrong side of even small trees. The good news is you can pop this on your RC car or tiny whoop (I STRONGLY recommed the Eachine E011) and upgrade this one. There is more than enough lift for the extra weight of a micro CCD camera like the Foxeer arrow micro or Runcam swift micro and a Vtx like the new one from fullspeed that is 25mW/200mW switchable to mount on the back. I'll be making such a change in the near future and reporting back in a new article in the tips and tricks section.
Early conclusions
This model is an amazing combination of well-matched parts with good assembly and a custom tune making it compelling on paper. I'm pleased to say that this transfers into flight characteristics and power making it an option you should definitely be considering if looking at a micro in 2017. I personally think this frame size that allows for a 2.8" prop rather than 2" is much better matched to this motor size and not nearly so sensitive to weight meaning for a more robust and enjoyable flying experience. My only real gripe is the video quality where camera light handling and vtx power lets it down. It is hard to argue at this price point though and in a future article I'll be doing a budget mod to address this. Most interestingly, I built a model from parts that was very similar to this before this model was announced. Cutting to the chase the PNP version from Gearbest was more quiet and felt more solid in the air (perhaps due to the tune/rates) than my own build. Power was similar: although noisier I think the DYS motors had an edge although for the small difference I prefered the ones in this PNP model. I preferred the adjustible power vtx on the model I built to bump up power but this is really starting to split hairs. This does have me second guessing my build vs buy strategy but I think this is testament to the well thought out component list Full Speed have chosen. Buy the Leader 120 from Gearbest  Firstly, thank you to Gearbest for supplying this model in exchange for a full review including my observations and recommendations from having built a very similar quad from parts. I'll review here and then run a series of tip, tricks, mods depending on how it flies stock. You can find the PNP version (no receiver) here. As at September 2017 try code HarvestRCnew7 to get this for only $US93.99! I'm going to skip the unboxing, I don't have anything to add other than the picture of all the parts included below, so straight to the good stuff.  The parts included and build quality have improved... First off the motors are no longer and unbranded red 1104 7500kv. They are now branded SZ speed and full speed but are still rated the same. From what I can see the shaft length extending through the bell is shorter. Great idea - the only job this does is to centre the prop which the screws hold on. Less stress when trying to put tight props on (looking at you Gemfan 2035) and you don't have a 1.5mm drill bit. Below is a comparison to my DYS 1104 7500kV. You can see my review on these here
The comparisons to these motors don't stop there. Both are similar external size, and the magnets are simlarly strong - very notchy compared to the racerstar motors. From there the leader 120 motors are better. Wires are multicore, slightly thicker and much more flexible and easy to manager. On spin up in betaflight they are so quiet and smooth! Not noisy like the DYS even when they were new. In fairness the DYS are powferful so if the stock leader 120 motors get anywhere near this I'll be happy, especially given the improvements. This flight controller and ESC is ubiquitous and first appeared on the ARFUN90. I've reviewed one in full here - in short reliable and well featured. What impressed me here was the quality of soldering and the cable managent, just so clean - see below. I wasn't going to compare my efforts but I'd already soldered in the receiver and the macro image makes me feel inadequate! From what I can see of the earlier reviews, this looks to have improved substantially.  Betaflight setup and the Flip of Death This model shipped with the full release at the time of writing - 3.1.7 (3.2.0 still in release candidate). Interestingly along with the physical changes the software settings have been changed to address some of the brownout/flip of death issues the early reviews had. Most notable digital idle is set at 10%. Since I'll maiden this with stock settings I'll go with that and see if moving back to my standard of 3.5% is still viable. 10% is not ideal for me as you will never be able to fully chop throttle for flips and whatnot. Cool to see that they have addressed it and looking forward to seeing if this issue may have gone altogether. I'll post some pics of the key betaflight screens for prosperity below (flip through them) but I intend to move to 3.2.0 as soon as I have completed initial flights and can confirm everything is functioning as expected. Weight I'm something of a lightweight jukie when it comes to miniquads, benefits include longer flights, better agility, greater crash resistance through lower intertia. See the gallery below for the various weight measures but in short 64g dry, 94g AUW ready to fly with the stock 2s 500mah battery. This include an ibus FS82 1g receiver which was not present when I too the photos. This is a very respectable weight for a micro that swings 2.8" props as these props generate a significant amount of lift in combination with a motor of this rating. All this and it includes my favourite beeper/led combo (reviewed here) - a beeper is a must for micro quads as you can loose them even in short grass! I can anyway. Size comparison to other micros This is not a big model by any stretch. The beauty of these micros - and to be clear this is still a micro - is you can fly in small areas (not indoors!) with less danger and concern to the public. They are also quick to get in the air and consumables like batteries and props are cheaper too. This model measures 120mm diagonally motor to motor and offers most of the experience of a 5" FPV quad. Picture below compare to an E011 typical tiny whoop and an 80mm EYAS x2 with 2" props
