Just looking for some general input on 3 blade prop selection. I have zero experience with them but would like to run one on a GP P-6E Hawk I am putting together. I will be running a Saito 1.50 FS and am thinking I will use a 17x6 2 blade for the first flights. Suggestions on manufactures would be helpful also. Graupner and Master Airscrew don't appear to go larger than 16 in. diameter.

Thanks in advance.
