My advice is set the Cap up to hang from the ceiling for a while, get a Four Star which uses the same size engine... Or build a couple of SPAD aircraft to increase your skill with higher perormance planes, THEN fly the Cap.

If you build and practivce flying the "CoroStang" from www.spadtothebone.com you'll have little to no problem with the Cap. If you can't fly the $10 to construct (plus radio and engine...) CoroStang, your Cap won't last long.
