I've noticed when in AUTO mode and my RC TX is turned off or goes out of range the throttle % drops to considerably low values. i.e. 15% The plane flies very very slow when this happens (8 m/s).
When RC TX is on or within range in AUTO mode the throttle ranges between 20-30%. But usually sits 23-26% for level flight.
Max throttle =40%
Cruise throttle = 25%
Min throttle = 0%
My question is why does the throttle drop so low when TX is not connected when cruise throttle is 25% Id like to fly longer missions and its better if my TX is not constantly on for hours. I've disabled RTH fail-safe for TX fail when in AUTO mode.
Thank you in advance.
