How to set throttle dead zone in fixed wing?

Hello, I’ve just started tinkering with a fixed wing plane; wanted to control it remotely with my joystick and was wondering how I could set the throttle dead zone.

Right now I can control the throttle with the right trigger, but its default value is so high that will make the motor start spinning without even pulling it.

just go into prams file and adjust your throttles RC input my is on CH 3 RC3_DZ,0 to how much you need

RC3_DZ: RC dead-zone
