I know this is an old thread, but it's the exact topic that I'm looking for.
I want to do exactly what Icarus and iskess did. Allow auto-throttle in auto modes and have it available in manual/FBWA from the momentary switch on my FRSky X9D.
I see three things to configure. The TX radio, the Pixhawk, and the ESCs. What I'm concerned about is the interaction of the revised throttle range with failsafe.
Assume I set the ESCs so that 1500 is neutral (off), 2000 is full throttle, and 1000 is full reverse.
I can set the RC radio so that the throttle channel outputs 1500 when the throttle stick is all the way back and 2000 when the throttle is fully advanced. I can also set up an override to send the throttle channel below 1500 when the momentary switch is toggled.
Do I still keep the failsafe setting in the Pixhawk below 1000?
I assume thr_min and thr_max are just for automated flight modes.
Oh...one more question. Do the spinners for the props ever fly off when using reverse thrust? Do you put locktight on them (or switch to nylocks)?
