| The 401/9254 will do you just fine until you get into high, high speed backwards flight then the tail might blow out on you. If you do the BBC, the OS70 is the engine to go to because you cant get cylinder liners for the OS61 anymore and today's 50's make as much or more hp than the 61 and are a half pound lighter in installation. That said, I love the OS61 as an engine, as a piece of machinery. Very well designed, well made and durable. I just wish we could still get the cylinder liners. Consider using the OS50hyper with the MP5 muffler and a CarbSmart and governor or the Thunder Tiger Redline .53 the same way. MUCH lighter than a BBC, plenty of parts support and more power than you'll ever use.
