PROP SIZE

[raby fink]

I forgot to ask in my last entry about prop size. I have a Brodak .049 going on a 1/2 Stunt Master. I also have a OS25 going on a Ringmaster, and a OS40 going on a Giant Stunt Master. Please let me know the proper prop size that I can use for each. I want to "tone" the Giant Stunt Master down some if possible because I realize that the OS40 may be a little hot for it. I think I will use Nylon props. Thanks again for the help.

   If you are talking a 25LA, I would suggest an APC 9-4 to start with.

Yup to what Brett says...
I am a believer that the OS .40 will run best with a 10 1/2 X 4 1/2 APC prop, or the 11 X 4 Thunder Tiger prop.....spin the thing up....
The .049 likes a 6X3....
Have fun!!!!
