Lightweight 3" 3S toothpick based on babytooth frame.
Very stable flight, high thrust to weight ratio, no propwash and very efficient.
I'm using betaflight 4.2.10 and bluejay 0.14 (@24khz).

AUW: 98g
Average flight time: from 03:30 to over 06:00
Disk loading: 3.47g/inch^2

Prop selection:
HqProp Durable T3x2 3020: Punchy and efficient, they lacks grip.
HqProp Durable T3x2.5x3: Grippy and punchy, require good throttle management because of voltage sag.

Battery selection:
I suggest using 3S 450mah LiPo.

Build notes:
I used 2mm thick babytooth frame: 3mm would be much durable but I didn't have any major problems in crash.
Motor wires needs to be elongated to reach the fc.
I used VHB double tape to glue fc, receiver and vtx.
Board orientation and motor resources need to be changed to have USB connector on the top like I did.

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..
