I bought ASP .52 from hobby partz, broke in easy, and now packed in the box, as this baby is gonna fly my GP Revolver. I used once ASP .46 2 Stroke, since then I've become fan of it. It never let me down. One more thing fishinpole, check out some of the videos of ASP .52 on youtube, how these motors are pulling some good performances, this engine knows how to pull off.

I'd love to use O.S. 4 Stroke and JBA 2 Stroke, future plans
