2 blade to a 3 bladed prop
Is there any reason I could not use a 3 blade prop on my Piper Arrow than I am building. Top Flite calls for 11X7. How do you do the conversion for the size difference?
Thanks for the help.

RE: 2 blade to a 3 bladed prop
If you power at the lower end of the power range, you will have problems with a 3-blade, however if you are using recommended max power, a 3-blade should be fine. Just drop 1" in pitch, or diameter from your 2 blade that flys the model best. Do not start with a 3-blade unless you really know what prop you want.
