hmmm you've given me much food for thought. Thanks.

I am still trying to figure out the different model numbers on horizons website. They have things wtih muffler J and muffler E but don't explain what the differences are , especially the differences for the price. Very ambigious website.

As for the OS 91 Surpass...like I said it is on tower for 229.00 and is available. But for the extra 50+ bux, is it worth the Saito black? That is my question. I think I want the Saito anyway because all the OS engines I see and hear seem to run underpowered to be honest. Or maybe they are just that silent. But they always have to me, a seemingly SLOW flight for the size they are. I've heard and seen different 4 strokes and they sound better and seem to fly more powerfully than the OS.

Anyway...any more info you have would be helpful bill and thanks so far! Like I said, Horizon carries the Saito..I just don't udnerstand the differences that are on there.
