i found an old Ace Whizard in my garage and began putting it togethier. my controller seems to be a 2 channel controlloer, and came with 2 servos and the transmitter and that bucnh. the problem is that will only 2 servos be good enough, i already have them to the rudder and elevation, how do i control by engine??

obviously i am new and have no idea what i am talking about, so please use simple terms........

thanks
