Fubar,

Isn't the CVA a Car engine? If so, That should be a very fast engine. Personally I wouldn't put anything smaller than a .15 on mine. When I ran a .15 it seemed very well mannered. But anything smaller other than a high performance engines seem like they would not have the vertical performance I would like to see. I am running a .25 HB on my alienator as well, and they aircraft only needs a light shove to get it in the air. My hand launch guy tells me I should be able to fly it out of his hand because it pulls so hard. The Shrike is lighter. I hope to be able to achieve somewhere in neighborhood of Mach.95 with a .25 on the 10 Shrike. Ok maybe a little less than Mach .95, but we'll see!
