Dr1Driver, i was just stating that this engine will make alot of power and also the new XLS model is better suited to larger props so you could always go up on prop size and lower rpm's. Compared to my OS.40LA, my magnum is almost as powerful, only 20% less.

OS.40la 11x5 @ 10500=.605HP
Mag .15 8x3 @ 18000=.512HP
