I have a Hog Bipe waiting to be built. The kit was cheap and the design is straight forward. Basic r/c airplane details all around. You won't have to mess with a cowling, inverted engine mounting, etc. Of course, nice results can be had with a round cowling from Stan's.

I still have nostalgia for the CG Ultimate. I have never flown a plane that can go from mild to wild so easily and still look like a real airplane. I am going to build the Hog with no dihedral and a larger rudder to try and make it handle more like an Ultimate.

I vote for the Hog Bipe.
