Prop selection

[Dr Hydro]

I have a friend that put an old stock gold head CMB 90 in a rigger and was wondering what prop he should use. He is using an OPS nitro pipe. Any reccomendations on pipe length? Thanks in advance for any suggestions!! Jim Fullmer

Set up 12.5" pipe length and use 1667 cup 5.8" Good luck!
