Hi Guys, thanks so much for the great responses. I flew again today and borrowed a friend's 22/10 Mejzlik. Wow, differnt airplane. It did everything better. I was seeing 6700 rpm with the slimline and I think I can go a little more lean after I get a little more time on it. I should have known because I have a 28/10 Mejzlik on a 3W 100 and it really performs well.

I do need the weight of the stock G62 with spring starter. And I have everything as far forward as possible. Right now the Jug's performance
is very nice, and the high speed passes are good......but tell me more about Ralph???

Oh and the comment about the scimitar working well for WWI biplanes is
very accurate. I have a Polikarpov PO-2 (WWI technology used in WWII)
and it flies great. The radial turns the 20/10 about 6900 rpm. The scimitar
is also pretty close in appearance to the full scale original belive it or not.

Thanks again for all the good input. DWR.
