Although it might be "fat" it's built light. I don't think it's meant to be a fast plane... so I would go with a 120. But then again, I was the one that originally had purchased a DZ140 for that plane.... Honestly, I wouldn't have used it. I think that plane would be beautiful with a nice 120 fourstroke but not 3D. The plane is surprisingly light.

Forgot to comment on the Cooper - The plane will fit... but it wouldn't fit in one piece. Even broken down, I'd have to use the entire car to fit the plane. 61 wings would go above the fully forward passenger seat!!! THAT is why I eventually sold it... :-(

This (below) does not a good plane transport make!
