Which Prop engine combo?
Ok, I discussed my new Scat Cat in the other thread, My question now is.. Engine/prop combo.
The plane comes with a New Anya .40 SS BB and it is turning a 10x6 currently. I have a new OS .40 SF ABC that i used on my ultimate and that turned a 10x7. Now which engine would power this plane better? ANd what size of prop should I go out and buy a few of. I am not looking for bleeding fast speed right now, as I want to explore the Aerobatic capabilities of this plane. I would assume that a different prop for Sport and a different porp for Racing would be in order?
Thanks in advance.

Maybe a little overstated, but trying to come up with common equipment for aerobatics and pylon racing is like purchasing an Indy car to take the family on vacation.
I cannot help you much with the aerobatic part of your question. The prop your are using sounds about right.
For Pylon Racing on a good quality 40 engine (Not a racing engine) I would start with an APC 8 1/2 x7 prop. Any more pitch than that might be a bit heavy. 6 1/2 or even 6 pitch might be better, depending on the power of the engine.
Running props on the ground and reading RPM has only limited value for pylon props. In the end you will have to try it and fly it to get valid results.
