I’m running MP 1.3.38 build 1.1.5990.37365. I think it’s the latest beta build. I hadn’t been able to get ESC calibration to work under any circumstances until yesterday when I again tried the MP version on 3.4RC1 with the PWM type=0. When I changed the type to 2, no luck, so for now I’ll just wait for the Oneshot125 calibration to get fixed.
I actually had it in the air without running the calibration since I have XM20As with Blheli fw and could manually set the ESCs.
