I just upgraded the firmware (3.1) on a DIY tricopter which had V2.8 arming just fine.
Now when I was testing arming, the three motors start by themselves and I can only accelerate them but not shut them off via radio. Is there a PID I have to
My first post here, I've been trying to setup a tricopter using APM 2.6 + GPS.
My first question: How to get the YAW servo to work?. Bars under Radio calibration are moving fine but when I power the tri I cannot get YAW in any direction.
