Off hand I can't remember the Watts, but I am using a 70amp ESC and have never had a cut out, so below that, I use a 16 x 10 APC Electric prop, the only other prop I have tried is a 17 x 10 cut down to 16 to give a broader tip, this is better for calm days as it slows the airframe better on down lines.

One other thing is I use 6S 4350Mah LiPo's so the airframe is slightly heavier than if you where using lighter LiPo's, I find it holds its line better at a higher wing loading, of course this is all just my opinion and I am sure others will have different views.
