Steve, That is the size prop on my 7-70 powered corsair so yes, too small! I bet a 22 x12 would still be small. 24x10 3 blade would be OK but I prefer more pitch. Not to sound silly because I bet they do not make them would be a 23x12. -Tom
thats what I thought, I have a 24x10x4 blade and that one is too much only got 3,600 rpms out of it, and the 23x14x4 is also too much, I will probably try and find a 23x12x3 or try a 24x10x3, I really like the looks of the 3 blade, TBM models has sent me a email saying they have come up with the Biela prop size for the 9-99 in the 4 blade and they say a 20x10x4, but that sounds too small to me,but I will keep experimenting til I get the 3 blade I want,-Steve
