Alt-Hold problem

Hi all,

I have problem with Alt-Hold mode - my copter goes immediately down when I enable this mode.
I am using pixhawk with Lidar-Lite. I tried without sonar, with I2C or PWM connection…

Thanks for help


A quick look at your log shows the throttle at a very low setting at about 1140 for hover.

In Alt Hold mode that would result in the copter dropping, unless you raised the throttle to mid point.

Have a read through the Wiki here

Hi i have same type of problem but instead my copter acceding without control. I did test without propellers and same thing happens. Throttle mid is set correctly( at least i think so). I use APM 2.7 control board.
