RE: Sundowner 50 with a YS110??
I'm very interested in what you did to that 1.10 to get 11,500 with 14x14. I can't get that out of mine on a 13x13N, on 60%. That porting you did must be magical. Did you check that with more than one tach?
Also, like I said above, ,I believe the Sundowner would be faster than the Dago Red. The Dago Red has a thicker wing.
