THE FROG 3INCH-O3 DRONE FRAME FPV

I designed it to tick all my boxes ;-)

[x] Lightweight

[x] Durable

[x] Vibration-free (or as close as possible)

[x] GPS compatible

[x] Battery bottom mounted

The proper tuning is ongoing and will probably be posted later on rotorbuilds.com, as the tuning depends on the motor you are using.

Vibration-wise, it is amazing, as you can see on the blackbox for a 1-minute freestyle flight. I know it's easier on a 3-inch frame, but there are no frame resonances and only one motor harmonic!

In the picture of the drone on the scale, it has a BetaFPV 4s 850mAh battery, and I get around 10 minutes of flight time. (sub250g)

This build also require some hardware : 2x M2x25 textured standoff and 1x M3x25 textured standoff

This new version is now compatible with the DJI O3 system. 

It has room for a GPS and it is now battery bottom mounted.
