OS .50SX, what prop

so I have an OS Hyper .50 that I will be running on a Wold Models P-40, I have a GMS .47 muffler, the muffler is a bit big, it's just a bit longer and just a bit larger diameter than the stock OS .61 FX muffler (#E-4010), so I feel this combo will work out pretty much the way I want it to, I have a few jugs of 30% to burn in it

too add to all that , on the lathe I have cut down the fins on an older OS .50 SX Heli head (silver head) to use

so what props are/were you using on your OS.50SX plane engines ??, I thought I would start there

thanks guys !!, keep them flying

Jim
