Hey there, Kram -

Thanks for the input. Indeed there are so many things that vary "how much throttle" is. I guess in fact it's not really "how much throttle", but actually "where is the stick". Not always the same thing. Apples to oranges, I guess.

I think both engines will do well, but I would rather only install one. I too have used O.S. and really like it, but then tried Saito for the .72 4-stroke and love it too! The Y.S. came as part of a trade, so I've not used it at all.

Are you personally having any loading-up with your 100 inverted?

Thanks!
