WOW!

Everyone,

Thanks for all the advice and assistance. There is a lot of good information here!

I'm partial to 4-strokes (I'm an energy engineer, and like the energy efficiency and engineering involved). That, and the high pitched whine of two-strokes kinda' irritate me--or was that just the sound of heli's?) LOL.

Anyway, I expect that the engine I use here will eventually find itself into another bird, so I'm not shy about investing a bit more up front with that in mind. However, the power/cost/weight ratios given by the 2-strokes can't be beat and it takes a lot of fuel to pay for the difference in cost vs. efficiency. There's a lot to think about. But the field is much more narrow than it was. I like the 4-stroke OS .56, but they are a bit too proud of that one! LOL.

Now for the second plane....hmmmm-----hahahaha (I can tell I'm about to get addicted again!)

THANKS AGAIN EVERYONE!!!
