Don't do it! Caps are my favorite, and you just need to keep the throws on the elevator down. Put a DA or ZDZ or BME, ect. If cost is an issue then get a Moki 2.10. The Moki will let you do it all with this plane. If you have the engine already, I would put it in a warbird or Super Decathalon... Something where 3D is not an issue.
