That is the expected behavior. You will need to configure for ICE (internal combustion engine) control and internal governor. Rotor Speed Control Setup — Copter documentation

It is definitely due to servo 8 being assigned boost throttle. That should be assigned HeliRSC. Looking at your previous post showing the Heli set up page, servo eight was assigned correctly. Not sure how it got assigned to the boost throttle function. Did you change anything?

At first, I did set it to heilrsc, and after finding that there is no effect, set it to Bosstthrottle to see if there is any effect.
