Thanks for the quick reply David. Does your Saito 72 provide unlimited vertical? I am not necessarily looking to hover the plane at 3/4 throttle, but I do want it to head straight upwards without stalling when I bury the throttle. As it stands, my 50SX has trouble providing the power for large loops (which may have been a blessing since I am very new to flying this type of airplane).

Thanks again.

Dave
