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:
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.
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.
Setup for flight - Betaflight
Like the other Fullspeed models they have customised settings in betaflight for the toothpick right down to having custom rates. Other than setting an arm switch nothing is else is needed other than the customisations you prefer. For me this is OSD and rates. It's worth noting that the nightly build of betaflight that this flight controller currently ships with is not 100% compatible with the latest version of betaflight (10.5.1 at time of writing). Some functions like switches and OSD are unavailable through the GUI. My recommendation is to save you diff file, update to a full release version using the Matek F411 (4.0 at time of writing) and apply your diff as needed.

Setup for flight - VTX
The VTX is locked to just 25mW output power and limited channels from the factory. before you fly for the first time please unlock it as below:
1. Press & hold the button for 5s to adjust Channel. Red LED will flash 3x & show the Channel. Short press for 1x to switch Channel.
2. Press & hold the button for 5s after step1 to adjust Band. Green LED will flash 3x & show the Band. Short press for 1x to switch Band.
3. Press & hold the button for 5s after step2 to adjust Power. Blue LED will flash 3x & show the Power. Short press for 1x to switch Power. （Only to unlock the transmitter so the power select mode can be accessible.）
4. Press & hold the button for 5s after setp3 to save setting. All LED will flash for 3x to show the Channel, Band & Power.
Flight performance FPV
Given this has a camera and VTX that is superior to anything in it's class it's understandably good - more comparable to a 5 inch quad. The only loss in quality comes as a results of the smaller electronics that surround the vtx which are noisier but this is a fairly minor quibble. I always forget how much a good FPV feed improves the experiences. Std disclaimer that Aomway Commander DVR is awful and what you see in the goggles (reception AND image quality) is much better. I will note the the Caddx F2 makes a bit of a mess of red light in bright conditions but NOTHING like the Caddx EOS2 as per the Eachine Trashcan.
Overall flight characteristics
The first thing I noticed is just how quiet this little quadcopter is. This doesn't get discussed enough and I think it is really important especially if you life in urban areas and/or a conscious of disturbing others. The next thing is performance is really impressive given the size. It is definitely not as fast as a 5 inch nor is as fast as a good 2.5 or 3 inch running 1106 motors but the agility makes it feel fast. The motors are not especially powerful and you never feel like you have as much control over the prop as you do with bigger motors but it is very smooth and unlike many other micros surprisingly vibration free. The flight characteristics are vastly superior and more predictable than any ducted quad. It is understandably faster too (including Mobula 7, Eachine trashcan)
It sounds like a weird mix of things as I read this passage but this combination makes for the perfect park flyer - quiet, light (and so safe) but fast and without the poor flight characteristics that plague the ducted quads, especially in any wind. I think this little guy will always come with me to take advantage of even small parks during lunch time or when I'm out with the kids with minimal chance of pissing the public off - very easy to pass off as a quiet unassuming toy.
Flight performance 2s
Without beating around the bush I found 2s to be the best feel. Throttle felt more linnear and the little quad felt more predictable in the kind of places I want to fly it. The 2s 300mah GNB HV surprisingly gave me about 3 minutes flight compared to 2 minutes in my original tinyleader and 2.5 minutes in my tinyleader modded to take 1.9 in props - quite staggering efficieny. I found that around 2s 450mah was the sweet spot - enough for over 5 minutes (!) of flight without hurting the performance on weight. My 46g 950mah battery was definitey too heavy - more than the quad itself! As Kabab has stated around 70-72g is the sweetspot.
Flight performance 3s.
There's no doubt that 3s is faster but felt the predictable throttle response wasn't quite the same as 2s. With a 3s 300mah battery got around the same flight time as the 2s 300mah. This tells me that somewhere between the maximum throttle on 2s and 3s the motors are starting to lose some efficiency and so my guess is a throttle limit of about 80% would greatly improve flight time whilst not limiting real world performance. The speed was fairly intoxicating but it did feel a little too fast for the control I had (my DVR on the left below). It's fair to say that a better pilot could probably manage as can be seen from Rohen's early garage flight on 3s (below right). You'll be pleased to know that the motors and ESCs handled the 3s packs just fine, I've now put through a dozen or so 3s packs. This hopefully means the ESCs woes are behind them and the tune is about right so as not to cook the motors.
I think the toothpick class of quads fits a really nice niche. For areas that are unsuitable for powerful 3-6" freestyle quads due to noise, space, proximity of public I think these are a great alternative without the compromises of flight charactertics like yaw washout as we find on brushless ducted quads. That said they are certainly not suitable for indoors like whoops are. An added bonus is the improvement in efficiency that is allowed by these large, light propellers.
What I believe sets the Fullspeed toothpick aside in the class of toothpick quads are the discrete components, especially the fpv system which has a good camera and a very good vtx. It is on the pricy side at around $130 but it does feel like a well balanced, easily serviceable model. This is probably my favourite fullspeed model since the original Leader 120 and I'm happy to recommend it if you are looking for a quiet, efficient park flyer.
