4" Stretch X 163g Dry weight. This thing accelerates and corners faster than my 5" quads. Feels kinda like cheating on the race track :)

Did you get your smart audio working on your tbs? I have same fc and vtx but can get my smart audio working.

Sorry just saw this now. Yes mine is working. I think there's a tiny pad you have to solder to for TX2 and enable smartaudio for that (if I remember correctly)

I just bought the omnibus nano F3 v2. I have been checking the motor numberin, but I´m puzzled. I see in your build that M4 = motor 1, M2 = motor 2, M1 = motor 3 and M3 = Motor 4. Did you get issues when setting up? I´m a total newbie and not sure if you can change that in BF. Thanks for your help. Overall, how the FC doing?

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..
