I located a NIB - JBA .56 at the auction site and won it today for a very nice price. Looking forward to getting it on the bench. From what I read, it sounds like an 11 x 7 prop should do it well.

I chose a larger engine because i want to mod the nexstar in due time. Turn it to a tail dragger, military green skin and mount my camera to it. Went to the LHS today and purchased some supplies to begin the modifications. Also I believe my next project will be a P-40 warhawk that will love the .56. When I get the .56 in action I will report to that thread BigMustafa pointed to.

Thanks.
