Diatone ER349 to Donut 3 cinewhoop conversion!

By Thomaat on Nov 09, 2019

8 886 4

So basically I converted a Diatone ER349 to a Donut 3 frame. I will post more videos of it flying around once I get around to it!
Here is the PID tune I am using on betaflight 3.5.1, the motors come down cold!
Flight times are about 3 minutes on a 4s 850mah. I will try a 1000-1300mah in the future.

If you have the right tune of course, it has 32 bit ESC's so RPM filtering should be no problem!

AirbladeUAV has done it again and this time they've brought long range to the 5" class!

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..
