I have a hangar a 540 33% with a DA 100,all the servo are program and are Hitec HS-5945MG through. The engine box was rebuilt a few years ago. The plane is a lot of fun to fly with a 100!!!. It comes with a receiver AR 9000, there's no batteries, if you like to run the engine or test fly, I can pull batteries out of my plane. There's no way I'm going to ship this!!!!!!!
