20% nitro? Will it run well on less? Raise the compression maybe? I don't know what it'll do with an APC prop(too pricey cause I break too many), I did run it with a 16x6 MA K prop, and I think the rpm was over 9K w/MCP(but wouldn't swear to it), but didn't like the spin up time. I think the 2 strokes, this one at least, is better off revving a little higher.

The thrust figures were from thrustHP? 14x6 @12K 12.7lbs thrust(stock muffler), and 15x8 @ 9.3K 13.1 lbs thrust. That puts both right in the ball park power wise. The YS and 20$ fuel, requiring much more cash to get there though. Of course with dif prop mfgs, the numbers don't directly translate, but I think the .91 2 stroke will more than accomplish his goal, and if a MCP will work with his airframe, the 2 stroke will exceed the requirements.
