A buddy of mine had a Wonder with an .18 on it and for it's size it moved out pretty good. Not anything extreme but sure has me wanting to get one.

I flew his a few times and they are so easy to fly. They are pretty predictable and very easy to land. His glided in for days before it would settle in. Cool plane thats for sure.

I think those Wonders and Shrikes are to cool. I have a few small .15 car engines and would like to see how it would work it it with a pipe. I have nothing else to put them in so should be cool to tinker with.
