The Q500 engine has undergone considerable development at this time. Photos are attached of engines and component parts for your review. More photos and CAD images may be seen at www.flycontrolline.com This engine uses a dedicated cast crankcase and a crankshaft that is integral with the rear ball bearing. As you can see these components entail considerably more work than a “bar stock” engine. Profi has manufactured the world championship engines for F3D RC Pylon racing as well as F2A Control line Speed, F2C Control line Racing and F2D Control line combat. Currently Profi engines hold world records for RC Pylon, Control line speed (AMA and FAI) and F2C racing. As you might expect Profi engines exhibit a very high quality standard of manufacturing.

The Profi Q500 engine is very easy to operate and exhibits a very low vibration level. These characteristics combined with the competitive performance should provide an additional choice for competitors in AMA RC Pylon racing.
