Will a saito fa 91 be enought engine for hanger 9 ultra stick,sixty series, thank you larry hammond

It will fly the plane just fine but it may not be enough power to get all the fun out of the plane that you'll probably want. I flew mine with a Saito 100 and an OS .91 2-stroke. Be forewarned, they build very nose heavy so putting the rudder and aileron servos in the tail is a good idea.

Thank you for heads up on weight,will put servos in tail
