Well, your wonderment, amazement, whatever (not really sure exactly WHAT you were trying to say) at the "newbies" with the expensive planes and motors can also be applied to the cost of "nitro-laced fuel". Again, I must assume here, but I'm guessing you're referring to the 30% nitro heli fuel that the larger Saitos thrive upon.
I ran this stuff for a while in my helicopters, but when my bulk-purchase contact left the business and I had to start paying regular price ($27 per gallon) for it, my enthusiasm waned rather quickly and I went back to 15% fuel.
I love flying the larger planes, but do not intend to spend a major chunk of my modeling budget on fuel. So I'm keeping a few small glow planes that don't guzzle the Cool Power 15%, and going to gas for the "big iron".
<<...OS was cheaper than Fox of K&B...>>
Man... that's difficult to imagine.

I realize you began the hobby long before I did. When I started in 1986, the LHS guy tried to foist one of those miserable K&B Sportster engines on me. I bought an OS 40FP mail order, and haven't looked back.
BTW, 7aso, I too have an OS 1.08 (in an H9 ShowTime), and I'll echo the sentiments here; it is a lot more engine than the 91FX of today.
