OpenRacer DJI O3 30x30 Stack Build

This build was inspired by Limon's OpenRacer frame. Just the thought of a DJI O3 build so small & durable with so much protection for the electronics had me firing up the Prusa in no time. Check out his YouTube build video below. All the info for parts & stl files are in the description. The only thing I wanted to add was a GPS bay on top, but the stl file was too complex for Tinkercad to upload (Ineed to find a free cad). His video showed a 20x20 build, but with minor modifications, I was able to make this with a 30x30 SpeedyBee F7V3. I had to raise the conopy stand off mounts with 3 washers to clear the FC, & used M3x30 tappered flathead screws in place of the arm teightening bolts to mount the stack. Have fun.

Hi,
Thanks for the info.
How much does it weigh?
Thanks

I really wasn't going for light weight. I just put it on my mailing scale and it comes in at 367 grams without a battery. I guess you can make it lighter if you don't include the arm/motor protectors.

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

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.
