Scott,

I was also looking closely at the RCV90 as it appears to be a perfect choice for slim cowled planes. How has it been for ease of starting & tuning, as well as power compared to a "normal" 4 stroke? Cooling idea looks good also. *LOVE* those exhaust stacks! Where did they come from? I promised myself that this would be a "fun" build & fly bird, but I just seem to get sucked into the "detail, detail, detail......"


Raston,
OS .91 was also up on my list because of the popularity. Will a TF muffler have enough volume for it or should I look at something aftermarket?

Speedster 1919,
I never really considered the ST as the only experience I've had with them was some old Formula 1 .40 stuff years ago. Anything special to know about this combo? Which 3 blade prop are you running? Could be a good option as it is certainly one of the lower cost ones....

Also considering one of the "Jett" motors, although hiding a small pipe would be difficult.

Thanks again,
Bob
