I wanted to build a tiny, open prop, 2s, digital drone I could fly anywhere. This is the result.

52g without battery

Build notes:

• I would have picked a different AIO FC, but this BetaFPV F411 was all that was available at the time. I understand the BMI270 Gyro can be difficult to tune and I am wondering if it is causing the vibrations I'm noticing at times.
• The Flywoo Robo 1003 148000Kv motors are rated for 2s and there is no lack of power
• I get around 3-5 min on 2s LiHV batteries depending on how agressive the flight is
• I tried a few different 3 blade 40mm props and the HQ prop 40MMX3 Tri Blade have been the best so far. They have the least vibration and don't come off as easy as some others.
• The Walksnail VTX is the original v1 Avatar HD Mini 1s with the Nano camera
• I used an ELRS receiver with a ceramic antenna to avoid having to mount an external antenna.
• I used the built in connectors on the FC to install the VTX and receiver during the initial build. When I rebuild this, I will solder the connections to streamline it and save some weight.
