Default 3 blade prop size for Moki 250????

Hello Fellas
so I have the scale solo adjustable 32x18 3 blade prop and I bought a couple SEP 32x18 3 blade props as well. Are these to big for this motor ? I been told maybe the better would be 31x16 3 blade. This will be flying a comp arf Corsair
we are also at 3500 not sea level.
many recommend prop size would be very appreciated, my thought would also be to make sure and properly load the motor so as not to over rev

Not sure if this is useful info, but I am currently using the SEP 30x18 three-blade prop on my Moki 250 powered Carf Corsair.

Plane hasn't been flown since July, but I believe I was turning 4300 rpm on the ground. Also, I don't use an electric fuel pump on my 250.
