In the world of brushless ducted quadcopters (whoops) I have been lucky enough to review most of the big hype products - Happymodel Snapper7 and upgrades, Happymodel Mobula 7, Full Speed TinyLeader and now the Eachine Trashcan. Clearly it is a silly but memorable name and it will surely be easy to search for online.
It is great to see a case included here and like the mobula7, enough battery power to get flying in earnest. The included XT30 is a small gesture but a nice touch nonetheless.
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 Mobula7 is made by Happymodel who also released the popular Snapper7 which I reviewed here. Like the Snapper 7 it is a 75mm brushless whoop but it is lighter and more importantly, designed for 2s batteries. The Mobula 7 is not the first ready to fly 2s brushless whoop to the market but it is by far and away the lightest at just 28g without battery. That means the small and light 0802 16000kV motors are able to reach their power potential even on the small 260mah batteries included in the kit and make this quadcopter move very quickly with extremely nimble handling.
Boldclash have recently released a new all in one plug and play fpv solution for brushed and brushless whoops called the F02H PRO following on from the F02H which I reviewed here. This includes:

Introducing the HB64
The HB64 64mm micro brushless quadcopter is available as a plug and fly kit from HobbyCool.com with either 14000kV or 16000kV 0603 motors. This review is based on the 16000kV variant and is my pick of the 2. It is just 1mm smaller than a traditional brushed tiny whoop but has much more powerful motors. It is 11mm smaller motor to motor than the brushless Happymodel Snapper7 (review here). I am happy to say that the HB64 has impressed me very much!
The HB64 brushless quad has a 4 in 1 esc and a F3 flight controller onboard. The 4 in 1 esc is rated to 5A and is Dshot compatible and has BLHeli_S configured onto it. These days, we are seeing several companies who are making AIO FC combo with built in esc but this stack seems to work very well. Added unnecessary weight is a big issue for micros but the HB64 weighing in at only 24 grams without battery or 30 grams all up including battery. This weight is impressive knowing all that is included. 4 in 1 esc, FC, battery, motors, props, frame and cam/vtx combo.
The camera/vtx combo works much better than expected. It has a discrete monopole/whip antenna just from vtx to top of frame pod. This antenna is great for the quad because of its extremely light weight. It is also unlikely to be broken because there is little surface area of the antenna to hit objects in crashes. This is an improvement from the original tiny whoops which had the cloverleaf antennas that are easily bendable and breakable.
The instructions that come with this micro quad are insufficient for the full setup of this quad. Included with my quad, there was a little sheet which had a diagram and labeling of the FC. This diagram only showed the FC and nothing else like the 4 in 1 esc, VTX diagram or receiver setup. Even though there is information on Google, it would have saved a lot of time and effort for the buyer to receive more extensive instructions. To that end I have spent some time here documenting what has worked in case others are looking for this information.
I was pleased to find that the betaflight firmware was fully setup with Betaflight 3.2 and only needs to be bound to the transmitter to be ready to fly. The pids and (ALL) settings have been adjusted to suit the quad. All that needs to be done is to bind the receiver to the quad, setup switches for arm etc. in the receiver tab and you’re ready to fly!
While I was setting up switches, after I setup arm, I also set up ‘flip over after crash’ which is a MUST for anyone that crashes a lot because it prevents those awkward walks of shame to rescue your quad. To use flip over after crash, just switch the switch which is assigned to flip over in the receiver’s tab and then arm using the arm switch, tilt the pitch or roll depending on the angle and objects around the quad until the quad is upright, then disarm both switches and re-arm the arm switch. You will then be upright and ready to rip again!
Since I run a Flysky radio, I used a small FS-RX2a pro receiver but the SBUS-based FRSKY receivers will work in the same manner. To set up the FS-RX2A Pro receiver, all that is required is the receiver to be soldered to FC by the GND, 5V and ibus. Then hold the bind button on the receiver while powering on from lipo. Now turn on the transmitter and go into bind mode and that's it! As simple as that and it is bound together. This receiver only works for flysky transmitters but works amazingly well for the purpose and size it is. Next step is to go into betaflight and make sure the serial based receiver (SBUS AND IBUS receiver) is selected and Sbus or ibus in configurators tab, Then in receivers tab, select switches for arm and I strongly recommend you try flip over after crash and beeper in case it is lost or hidden behind something because this quad is surprisingly easy to lose behind a cabinet etc.
Finally a good flying micro brushless!
Before I saw this I was hesitant to try another micro build after my previous Eachine H8 with AIO camera and tiny whoop. This is because back when I had those 2 quads, the power and components were not up to acceptable standard and the power was unbalanced so one motor would normally be powered more than the other 3 which created a lot of issues for the pilot. That is why I did not recommend them before. But all I can now say is “WOW”. From the first battery of this quad, I have been impressed. Within a year and a quarter, I can see the huge improvement that has been made in the performance and quality of micro quads, especially since they are now brushless which allows them to have more power and a much longer flight life. Moving forward into the future, brushless is becoming very popular because it allows for a lot more power than the brushed micros, lasts much longer and is more durable and can save weight because of the new ‘Naked bottom’ motors.
While flying this micro, using the first 30 batteries, I was very impressed with the 3 - 3.5 minutes of continuous flying which is great flight time for a micro like this. But after the first around 50 packs through this micro, the battery life shortened to 2 minutes to max of 2.5 minutes before I started to feel the battery sag. This is not that much of an issue because it was only because of the batteries’ life time. You would have much more fun if you purchased at least 4 260mah 3.8V batteries and gain longer battery life because the flying time would be more spread out over multiple batteries versus the 1 260mah battery that is included with this micro quadcopter.
I was really happy when flying this quad with the AIO camera quality. The quality and zoom of the lens on this camera cannot be changed, but as a stock unit they perform amazingly well. Everything in the camera’s sight is visible and surprisingly clear for a nano camera. The quality of this camera in my opinion is comparable to the “Stock” Foxeer HS1177 fpv camera with all the colour and clarity in the view. The camera however is fixed view. This means that the camera is fixed at a 20° angle. However, it works very well with the power and the weight of the quad while keeping the speed fast.
The video I experienced with this quad has been more than enough for what it has been designed for. Flying this quad indoors, the video feed can travel through a couple of walls before severely breaking up. The antenna is well covered and at 25mw at 12 channels, I have not had many issues with the range unless flying between multiple walls.
In conclusion, the HB64 micro brushless quad is an excellent micro quad for anyone from a beginner just getting into FPV to a long-timer FPV pilot for those indoor sessions or just some fun for those rainy days. It has more than enough power for indoor races or to rip around the house/warehouse. Its size and power also allows it to hit those extra small gaps that are impossible for larger micros or 3” quads to hit. Its advantages overlap the advantages from any brushed “Tiny Whoop” and for the HB64’s price point, it is definitely worth checking out and potentially worth buying if it ticks your needs. This quad is also very very durable. I have crashed it from high, slammed into many obstacles and it has just held up without any bent props because of the included prop guards. Within my first 20 flights, I crashed into a deep puddle of water where this quad was fully submerged for several minutes but after putting it under the hair dryer and letting it dry off, I plugged it back in and it worked like it did before the soaking. My last point is to address the quality of the solder joints and construction of the quad. Every part of this quad appears to be well thought out and as a result is strong and durable against many obstacles. In my opinion, I would recommend this quad 100%.
The HB64 micro brushless quadcopter is available at HobbyCool.com:
After several false starts including the FullspeedRC beebee66 which looked so promising (review here) I've finally found a real brushless tiny whoop - the Happy Model Snapper 7. This 75mm brushless quadcopter is 10mm larger in diagonal motor to motor distance than a typical tiny whoop or clone but can still be very much classified as an micro indoor quadcopter. I'm pleased to say that the awfully named Happy Model Snapper 7 exceeded my expectations in practically every area.
What is included?
The standard version is $10 more than the basic version and simply speaking offers superior value for money. Included is:
As you can probably see above the standard version includes 3 batteries instead of 1 and a 6 channel charger instead of a single USB charger. Because I was so impressed by the charger, I'll call out here the details of what made it so special:
Quad specs and discussion
Key specifications of the quad are:
The real innovation and star of the show is the integrated flight control/ESC/receiver. The flight control and BLHeli_S ESC on the same board is nice and a useful step forward from spearate boards as on the BeeBee 66 that mean it is more compact and weighs less (4.3g for this board). We've seen integrated receivers before but not with an SPI interface as this one has. In theory the SPI interface is much faster than the SBUS interface (gyro is connected via SPI) but for practical results this frees up a spare UART and ensures you get FULL telemetry (confirmed on my Taranis Q-X7s). Addionally it means that rather than choosing a serial receiver in betaflight, you choose a dedicated SPI receiver and can choose between D8 or D16 for FRSKY or AFDHS or AFDHS2a for FRSKY. Lastly binding is easy! you no longer need to use 3 hands to hold the tiny button down while binding - power on and then hold the bind button down for 2 seconds. Bliss!! The Crazybee F3/ESC/RX is available separately in FRSKY and FLYSKY versions
Nothing much to note about the AIO camera from spec perspective, nor the motors - the real test will be in flight. The frame however is intersting. The rings around the props look like ducts but are actually just protectors meaning you should expect flight performance more like a typical guard-less quadcopter rather than a ducted whoop. Guards look to be cast from 7075 aluminium and are integral to the frame, i.e. cannot be removed.
The instructions that come with this model are succinct, well written and complete. It goes into detail with receiver choice in betaflight and binding procedure due to the SPI interface. As mentioned above: Easier to bind and choose the correct recevier. For flysky users it is particularly useful that you can choose between AFDHS and AFDHS2a. You'll be pleased to know that betaflight has been full set up from factory for all the elements that are unique to this quad althought the PIDs are stock (yet run fine). Please see below for stock betaflight setup and my comments in the gallery below:
It's worth noting that since this runs BLHeli_S, all of the latest Dshot commands are available including motor beep and anti-turtle mode aka 'flip over after' crash. Both work very well :)
I've seen a number of brushless whoops that have looked great on paper but none yet have actually bettered the flight experience by a simple brushed whoop like my santa whoop (part 1 and part 2 reviews here). That's because until now the brushless motors haven't scaled down well and offered poor power and efficiency. This meant they had no better thrust than a good brushed whoop and much worse battery life.
I'm really pleased to say that this model is different. Yes I know it has a 10mm larger frame and a 450mah battery but performance is superior to even a heavily modded whoop. What does this mean? It can better recover from manouvers and it is a more viable outdoor flier on still days. Punch outs are surprisingly good! As you can see from the video it will happily navigate a playground and trees. The flight characteristics are really interesting. I'd liken it more to a micro burshless than a whoop because of the extra power and lack of full ducts. This means I can be more aggresive with cornering using more roll rather than the yaw-heavy flying I do with whoops. Further to this it makes me more confident in acro mode whereas I find a whoop in acro mode really foreign. In tight spaces and obstacles and at lower speed (e.g. indoors) I still feel more comfortable in angle mode, just like a brushless whoop.
For flight time I got about 3 minutes when charged to 4.2v or 3.5 minutes when charged to 4.35v. Open field flying dropped battery life to about 2 minutes but this is not typical flight with a micro like this. This tells me these motors are most efficient in the 30-80% throttle range which is where most tighter flying is done - like the playground, indoors or around small trees. Nice to know the power is there if needed though. I'm not a fan of brushless motors smaller than 1102 but think these 0703s are actually pretty good - particularly with this combination of components. Furthermore they are the quietest sub-1102 motor I have heard. Spares are available here: https://www.gearbest.com/motor/pp_1717534.html
I was really pleased with the image out of the little AIO cam - it was as crisp as I've seen with as good a colour handling as you can expect for this type of camera. The camera angle adjustment was really nice and with the power this offered a well thought out capability. Video signal was very good even around trees and I started to drop RSSI on the control link well before video deteriotation before travelling out on an open field. I think the receiver antenna location could be optimised (below) but think you'll struggle to get the 300m claimed range... <Quick update> I've since routed the antenna up through the canopy rather than underneath. I think the reception may be marginally better but certainly no more than 100m in line of sight conditions.
The HappyModel Snapper7 is an excellent supermicro brushless whoop-style quadcopter that is available in a great value 'standard' pack which includes 3 batteries and and versatile charger. For it's size it is very light weight thanks to the heavily integrated FC/receiver/ESC board that includes the very latest receiver interface that makes setup extremely simple. By combining this with well made 19000kV motors and a suprisingly good AIO camera they have created a brushless tiny whoop that lives up to what we've wanted - a familiar whoop style quad that is suitable for indoors with a level of power and response that micro brushed quads just cannot achieve. Furthermore it feels much more at home in rate mode (acro) flight compared to a ducted whoop. Unlike earlier brushless models this does not come at the cost of battery life where 3-3.5 minutes flight time is realistic. Only time will tell how the motors and aluminium prop guards will hold up but with 20 or so packs through I've not caused any permanent damage plus the motors are still running quietly.
The Happymodel Snapper7 is available in a basic bind and fly package with 1 battery and a simple charger for just $85 in flysky or frsky versions but I'd recommend instead going for the $95 standard package which includes 3 batteries and an excellent 6 port charger.
I'd happily recommend this as more powerful alternative for a brushless whoop for indoor flying and even outdoor flying in no or low wind. Unlike a the heavier brushless ET100, ET115 and ET125 models, the light weight will have much less chance of damaging your home with crashes when flying indoors.
