Return to launch airspeed parameters

Hello I was just wondering exactly which parameters are used to specify the airspeed/throttle level when rtl isactivated? My plane is nitro powered and has an airspeed sensor. Is it the airspeed min/ max? Or another parameter? I wasnt sure if the rtl is considered an “auto” mode. Thanks!

It is an “auto” mode and will use your cruising airspeed.

How exactly do you set the “Cruise speed”? Is that a specific parameter? I have been searching for the answer for weeks and the plane “kills the throttle” to reach set altitude then flies around in rtl loiter and then eventually adds throttle and begins to climb… then it kills the motor again and repeats the process…

Thanks for your reply!
