BEST PROP FOR 3W85 TWIN?
I just acquired a used 33% H9 extra 330 with a 3W85 twin on it. No prop. This is my first gasser over 50cc and i not sure what prop to use. I like the TBM props so that is what i will buy when i know the size. Thanks for your input. Also does anyone know where to get the original manual for this engine?

Hi,
In 3w props, you want a 24 x 10 and your engine will turn 6700+ rpms. If the plane is draggy like a pitts, you may want to use a 26 x 8 and the rpms will be in the 6600+ range. I have two of these engines and they run sweet.
If you send me your snail mail address, I will xerox you a copy and send it to you.
