Default C-spec on a plane?

Not quite sure where to post this but...

I have a 91 c-spec. I am planning on putting it on a plank, don't have a clue what size prop to use. I will be needing a 3-d setup.
Thanks in advance, Brent

A 14x6 APC is good choice for normal flying.
A 15x4-15x6 APC for hovering.
I prefere the APC 15x6 for my MVVS 15cc (.91) twostroke in my U-Can-Do 3D .60

Do you have any advice regarding using an O.S. 91 C-Spec in a GP Lancair ES 60? Prop size? Engine RPM to be expected?
