This looks like so much fun to fly!
It's so light you can pull out of any manouver.

Nice build, I recognise that canopy from somewhere ;-), I'd suggest raising the TPA a bit and reducing your P values a bit to help with the high throttle oscillations.

What thickness is your frame ?

5mm thick 3K carbon fiber. Going to replace the canopy by Dave_C_FPV's canopy design though.

Flies pretty well! I think it needs some tuning but it has got lots of power. I will try to add the DVR video.

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..
