Let me suggest that you make your own from an XOAR or Falcon ELECTRIC woody. Shape it like an APC, thin the blades down and sharpen the TE. Then cover it with 3K carbon cloth and epoxy, and bag it. This is a proven working concept that I have used on many props. It sounds like the engine should turn something like a 22x10 or 22 x 12. And BTW, any APC of this size will weigh about 200 grams. The woody-carbon hybrid weighs about 85-90 grams. Juuust a little weight savings.
One of the better props I've made for my GT33 is a 20 1/4 x 12. The engine loves that prop and it is very similar to an APC blade shape. APC's are the best in design.
Hi Matt,
I agree that the new 185 APC may be around 200 grams. The 20.5 X 10, is 35 grams heavier than the 19 X 11 i used on my 170 cdi. A 22" prop less than a 100 grams would be great. 100 grams is a huge amuont of weight to save in a pattern ship.
APC props are an excellent prop. If only they would make them lighter.
