Not sure what radio you are using, but on my JR 10X, I can set a "throttle curve." This allows you to tailor the throttle response. You can make the response flat in your "torque rolling" regime. For IMAC, I usually try to set the throttle curve to give very linear power output. Gas engines typically have a very non-linear throttle response - power goes up very quickly in the first half of stick movement and there just isn't much after that.
