What is the recommended propeller for this?

I have bench tested the Master Airscrew/Windsor Propeller 5 x 4.5 2 blade which draws 27-28 amps on 4s. Also tested DALPROP 5045 5 Inch 3-Blade and it draws 27-28 amps on 3s. APC E 6x4 on 4s gets way to hot to fast and I think would have burned the wires out if I hadn't pulled the power. On 3s still too hot. I am running this motor on a pusher airplane ( FT Alpha) and spend a lot of time at full throttle. I hope to test fly tomorrow. I think airflow will help and letting the prop unload in the air helps too. I'm am replacing a 2204 2300KV for more performance.
