how do i center my throttle servo, i got the mammy back with the picco .27 and i noticed the hobby shop guy had my throttle trim all the way to the left. so that is actually giving me less throttle. i dont need it yet i am still breaking in the motor have not yet shifted to second. So how do i re center the throttle servo.

i also just got one of these
