Maiden Flight

Edit Jan.25/20 - If it's so good as a 3" wouldn't making it a 4" be even better. I contacted Nick at CNC madness, and he helped me by modifying the design by making 5mm thick arms that are 20mm longer. The result is now, its capable of using 4" props. Hovers super smooth and Under 250g with a 3s GNB. Maybe tomorrow I will get to fly it.

Update March 9, 2020 - Its so good as a 4" lets make it a 5" now this is something really special. Nick at CNC madness helped out again stretching the arms another 15mm and decreasing the thickness to 3.5mm to save weight. I also upgraded the camera to a Foxeer Predator Nano.....so much better

I absolutely love the evolution of this, it's actually a solid platform. That's crazy - I wish I had thought of converting my 5" platforms to this in 20x20, because that end result is phenomenal.
Gorgeous build too.

Thank you! I appreciate the compliment. I may have to build it again. I had an incredibly bad crash a few months ago and completely destroyed the frame including bending two standoffs.

Mar 04, 2021

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..
