Magnum Engines XL 91 RFS Blue R/C 4-Stroke Engine
- Product Review (submitted on May 26, 2014):
First 91 awesome performance. Installed it in my Top Flite P47 and after three seasons runs like new. Second 91 not so good. I installed it in a Top Flite AT6. I broke it in as manual recommended using 10% fuel containing castor oil, Omega brand. Just started my second season and engine threw a rod. At least the plane was on the ground. OBTW I'm out of the warranty period.
