I just bought a Giant U-Can-Do and was wondering if the new ZDZ 40 RE-F3A engine would work good in this plane.

Its proabably a good power combo,not sure if the narrow fuse and cowl will take well to it though.

Actually I wpuld go with one of the DL 50's, they are strong and not too big for the U-can do. there are a few of the second generation ones in the market place and the brice is a little better than the ZDZ.
