gotcha...did you ever get a PM from me, I thot i sent you one Ryan.

i went ahead and got the graupner 3 blade 40mm RIGHT propeller....it's 4m thread, hope i can find the proper propshaft & whatever else I need to attach it... at one of my local RC hobby stores. i was expecting the 40mm to be bigger then it is....i would gotten 45mm isntead, but they didn't have any....they skipped and went to 50mm....oh well we'll see...hopefully the 40mm is big enough.
