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.

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

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. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
