Thank you for you reply, but my motor is not on that paperwork. Mine is GPGM4625, the paper that came with covers several motors in the 35-36 range. It gives a list of props but doesn't specify which ones are for which motors. Also the two links are dead Greatplanes doesn't exist any more

Rimfire 35-36-1500 Outrunner​

• Trainer & Sport Performance Weight Range: 5.5-7.4lb
• Aerobatic & High Speed Performance Weight Range: 3.7-5.5lb
• Propeller: 9x6E-12x6E

In general if you have a slow plane use coarser pitch props and finer pitches for faster ones.
Start with a smaller diameter and increases it while monitoring amp draw and motor and battery temps.
Find what other people are using on the plane your want to fly.

Props are not an exact science and the best one greatly changes depending on what you are flying and how you want it to fly.

Thank you. Unfortunately, almost no one has the plane I want to fly it's been out of production for 30 years.

The instructions say use an 8-4 with a 0.15 engine. I think with 3s it will be a rocket. The plane is supposed to weigh 3 pounds.
