Engines - long

[Rcmaster199 at aol.com]

Jerry, we have some pretty good carbs so the idle and mid range shouldn't be 
too much of a problem, as long the timing is appropriate. I was even thinking 
of something along the Koger belt drive reduction unit powered by something 
like a 120 or 145. 

If Nat can turn a 17x10 in his OS 90 straight out at 7.5K, then it should be 
possible to reduce the output of a 145 down to about 6K on a 22-24" prop and 
keep the engine happy. It's times like this that I wish I had a real machine 
shop around. I can only do so much with hand tools.

The webra 160 is a nice rig but it will not turn the large dia I want unless 
it is reduced.

BTW did you put the electric on the back burner?

Matt
Matt,

You forgot the 400 rpm idle.   : )

BTW - I'm currently flying a motor just like the one Bob describes 
below (and it's not made by OS).

Thx, Jerry
