3D printed 3" Whirlygig tricopter by 1Smug_Bastard using PLA and an Ender 3 Pro. Choose your flight controller carefully. I wasn't able to get DRonin to work with this stack but BF 3.2.2 out of the box works well enough. It's so small I don't know if I miss the Auto Tune and Servo Calc functions in DRonin. Working on a remix with integrated prop guards. I should have used a smaller VTX but its what I had lying around.

Another remix with prop guards.

If you point the rear servo downwards you can make it into an inverted-tail tricopter and enjoy big tuning benefits: https://www.flitetest.com/articles/inverted-tail-tricopter

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people.
