Engine Revs drop when switching from Manual to Stabilize mode

Posted by Ken Hunter on January 15, 2012 at 4:16pm

Hi All.  

I'm fairly new to ARDUPlane Mega 1.  I've set my modes initially as 1. manual, 2. Stabilize, 3. RTL.

I've gone through the setup and calibration prodedures. When I move from Manual mode to Stabilize mode my (electric) throttle revs drop by around 20%.  When I switch back to manual mode (or to RTL) the throttle revs return.

Has anybody experienced this problem, or can you point me in the right direction?  It might just be me missing some configuration step.

Regards

Ken

    Hi Ken,

    Have you set the maximum throttle setting for the autopilot to 100%? I think this defaults to 75% so if you switch on any of the augmented modes (i.e. anything but manual) you will not have full throttle authority, so full throttle will only give you 75% power. You can change this setting on the Mission Planner configuration window.

    I hope this helps!

    Owen
