After seeing some other folks do it, and having  done it with model airplanes, I'm considering attempting it.  Has anyone  else considered doing it?

  

 My two major concerns would be the  harmonics and the potential for asymmetric thrust (one blade pulls more than  another), but I've read plenty of accounts of folks making their own with great  success.  

  

 Thoughts?

I've not heard of anyone trying it on an RV10. I suspect it's because 

most folks opt to install a constant speed prop in order to extract the 

most performance. I'm only aware of one -10 that was/is equipped with a 

fixed pitch prop, and every time I see/hear of it; its for sale.

Andy,  

    Impressive thought to be willing to take on such a task!  However, aside from the design and construction issues which would not be small, the RV-10 seems to be the type airplane that really benefits from a constant speed prop.  IMO, the short takeoff roll and impressive climb followed by very nice cruise speeds would be compromised with a fixed pitch prop.  The constant speed prop also helps get the beast slowed down on approach so a fixed pitch prop would require a little more planning on arrival.  The great thing, though, is you can do whatever you want.

Andy –   

   

Dan Horton carved the prop for his bi-plane project.  It was a major ordeal.  He had an experienced old-timer carve a one-blade blank, built a duplicator, then had trouble getting a blank that was up to his standards.  After much time, effort and no small amount of angst, he has a beautiful prop that he carved himself…
