Man... I'd have to respectfully disagree..... I found that 4 strokes and 2 strokes fly totally differently... Power curve is different, throttle transition is different... Everything seems different to me.... However... I guess I could say the power is simular between the Irvine .53 and the Saito .72... I've flown both on a Pizazz and they have simular power. I just liked the Irvine better.

Just my 2 cents
