tiggerinva-thank you for all of the information, and the links were very helpful as to showing exactly what you were referring to. if i can find a decent local field ill probably get a 40 trainer and buddy box it. otherwise ill get the ripmax, in the 3 channel setup i am only missing the servo on the wing right? but from previous experience i used that servo more than the rudder. how well will it fly with only 3 servos? thanks
