The Turbobee 136RS from Iflight is a Toothpick drone, 3 inch, designed to handle 4S LIPO (you can use it on 2S and 3S too), and specially for racing (with FrSky/FlysSKy or TBS Crossfire).
The first thing that you will noticed with this quad is the design and the quality. It is high quality everywhere, even the TPU canopy is well printed.
So I decided to try this quad mainly indoor right now, because it is designed for racing so it is a perfect match to test it on a led race track.
The frame is a 3mm carbon chamfered, for a 136mm wheelbase. The frame accepts only 11XX motors (so 9mm mounting hole pattern), and 16×16 stacks.
Moreover Iflight added a lipo foam so the LIPO will not move at all during flight, and their strap is good too !
The total weight of the build is around ~65g so not bad with 1104 motors.
The canopy is really a racing one, with a good profile to protect mainly the camera (the stack is exposed) and the receiver (it is inserted and blocked in the top of the canopy, which is really clever.
Moreover this canopy add a special hole to maintain the VTX antenna strongly, and also for the antenna of the receiver where you can use some tube to protect the antenna !
The canopy is maintened with 3 screws and it will not move at all.
The HQProp T3x2 are used in this build and it is really good props, well balanced and perfect for toothpick quad.
The SucceX F4 Micro stack is the V1 version, so up to 12A. It is a 16x16mm stack, with plugin motors so pretty easy to change them if needed.

The BeeMotor 1104 4200kv can support up to 4S. They have also a double bearing and are pretty light with ~5.4g. I find them efficiently and they could be nice on other builds too. The shaft is 1.5mm and you can use TProp with screws on them.
Iflight decided to use the caddx EO2, it is not a bad camera but right now we have better one like the Runcam Racer Nano, the Runcam Nano 2 or the Foxeer Predator Nano 4.
Nothing to say about the VTX, the job is done well and you can swith the frequency as usual via the OSD, and the output power up to 200mW.
SucceX Micro VTX
- Power : PIT/25/100/200mW
- Antenna interface : IPEX (UFL)
- Telemetry: IRC Tramp
- Size: 17mmx27mm

Nothing fancy in the box, some spare propellers and lipo strip, the minimum to avoid to buy spare parts quickly.
If you are doing indoor racing and looking for 3inch BNF toothpick style it could be a good choice, specially the fact that this quad supports 4S.
Personnaly I found it a little bit floaty, you could see that in the video, it doesn’t grip as the LarvaX from HappyModel so I lost a little bit of time in the race track, but maybe with a little bit more PID tuning it can be interesting.
But you will get 5min of flights with a GNB 3S 520mah or a BetaFPV 4S 400 mah, so it is pretty impressive and interesting if you are looking for such features.
If you plan to use it outdoor it is also a good choice, even if the stack is more exposed due to the canopy.
