Eddie,
I haven't given up on the 3 or 4 blades quite yet , they are noticeably much quieter than any
of the 2 blades , just need to find the correct size and pitch. Dave Shadel suggested a 16x6
but this size had extremely loud prop noise and let the engine rev too high. One of my flying
buddies has a few Graupner 3 blades I am going to try but they sure have some wide blades ,
don't really look too efficient and the prop slot in the Tru Turn spinner doesn't fit . This is a
challenge , we need to figure this one out.
