I had this prop on an VW 2100  and and the bigger version on the Sub 81. The 
small prop hit a wall at 140 mph. The Sub did not have enough HP to spine the 
big 1. The RV guys tried the large one and a couple of them lost blades and 
crashed. The folks at Ivo were VERY nice about taking the small one back. I did 
not buy the big one direct from them. I know if you tell them it is going on a 
KR with a VW they will not sell it to you.

That's very true, it does make sense to have in in-flight adjustable prop.
That way it can be adjusted, it's a good point.

I've seen this one as a thought but heard a few bad things about it, but the
bad things were based on years ago issues, would a company still sell
something if they hadn't worked out those issues (maybe I'm naive)?

Though not your standard type adjustable prop but lighter maybe?

Anyways good point and another item to think about when going turbo.
