I purchased a used 1/4 scale CAP 232 from my local Hobby shop. As far as I can tell it is a Hanger 9 that has never been flown. I am using dual servos for the elevator and rudder mounted in the rear of the airframe to off set the weight of the engine. I want to run gas but I am having trouble deciding what engine to run. The hobby shop owner thinks that I should use a 26cc CRRC or Zenoah but I want real 3D power and am thinking about a 40-45cc. Does anyone out there have any suggestions? I am also modifying the airframe (lengthened the ailerons to meet the fuse., reduced weight where I can get away with it, and double beveled all of the control surfaces. I expect the flying weight to be 12-14lbs depending on the engine.
