This is the rebuild of my first b344 after it spent many months in the ice. It's insanly fast and efficient thanks to it's light weight (140 grams) and low surface area (25mm body and 12mm wide tapered arms) It can cruise at 40mph using 9-11amps and 80mph using 55-60amps.
Fastest speed so far was 93 mph on 5s with a broken prop. I know it can go MUCH faster!
The therotical thrust to weight ratio is 13:1 on 5s with 8in props.

I consider this frame a failure becuase I never came up with a good anntenna mounting solution(I would avoid buyingthis frame for that reason)

How is the HD footage? I imagine it's difficult to iron out vibrations with such large props.

The footage the footage I get with stiff props is suprisingly clean, but flexible props with a large blade area (even after balancing) produce nasty jello at certain rpms.

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..
