Fail Safe/RTL Motor Speed Setting

Getting ready to finalize Fail Safe and RTL settings and puzzled on how to set motor speed, altitude, circle diameter etc. Or is there a complex algorithm that takes speed, altitude and distance to home into account?

Also, is there a way to bench test the motor speed?

I would like to set min altitude (AGL) for RTL so as to account for highest objects in potential flight path. I would also like to optimize current draw for max efficiency should I get stuck far away. In other words I would not want WOT to home. I have searched on Google and within the Forum but cannot find the details.

Your help is appreciated.

BR,

Steven

  • MY CONFIGURATION: 

    1.  PASSED THROTTLE @ MODE STABILIZE/ACRO/MANUAL

    2.  FAIL THROTTLE @ MODE CIRCLE/CRUISE/RTL

    3.  ENABLE THROTTLE_SUPP_MAN

    3A.  SUCCESS THROTTLE @ MODE CIRCLE/CRUISE/RTL

  • I am somewhat new to this too but have been testing rtl for the past couple days with success. I do all my configurations through the apm planner. Under the Flight Planner tab in the Waypoints section, change default altitude to your desired altitude keeping in mind if the absolute altitude box is checked or not. (Checked Absolute Altitude means MSL/Unchecked Absolute Altitude means AGL or the altitude you start from). Default altitude also serves as your rtl altitude. Also, the number you type in for altitude needs to be in the same units as selected for the planner units (under Configuration tab, planner, select your desired distance units). As far as throttle amounts, you can change the cruise, max and min amounts through the configuration of the ardupilot. The APM will use max throttle to if it needs to climb, min throttle to descend, and cruise to maintain altitude.
