Hi

The smallest prop you would want to use on the RCV90SP is a 16x16.
Otherwise you can pull a 17x13 or 18x12 2-bladed prop.

If you want to look at 3 or 4-bladed props, you would look at a 15x13.5 3B or 15.5x12 4B

I hope this helps
Best regards

Thanks for the answer, I am really looking at a 3 blade prop for scale, I have been getting conflicting info from different sources, and I want to run the biggest prop I can and still get scale speed. You recoment a 15x13.5 3B how will a 17x12, 17x10 or a 18x10 do?? not enoughf pitch ar just too big for a .90 SP? How about a 120SP to push them?? Thanks a bunch..V-12

Hi

A 17x12 might be okay if you can find one. Or a 17x13 would be even better. It is possible that a 10 pitch wouldn't be enough.

I hope this helps
Best regards
