I’ve built the stable firmware for a v3 target. When I’m in manual mode I’m getting some strange behavior from the throttle. The actuator_controls_0 (which I expect to be thrust), gives a value of ~58 when the stick is centered and near 0 at full stick up or down.
I’d expect a value around 1.0 at full stick up. This is what I see in SITL.
Here is the plot of me moving the throttle stick full up and down (note the peak occurs during center stick).
The pertinent part of that log:
Your hover throttle (
MPC_THR_HOVER ) is set to 59, which is out of range. I assume you meant to set it to 0.59?
Doh! That is absolutely correct. I saw that in SITL the value was set to 5900%.
Funny this was protected against in both SITL and 1.8.2. I’ll check if lowering this value fixes the problem.
I think this still looks like a bug. I’ll post it to the issues on GitHub if I can confirm that MPC_THR_HOVER is the culprit.
Did QGC not protect you from setting that value?
It got set in a startup script and my guess is I didn’t reset the parameters.
