RE: Which Cub Builds Easiest ??
No, but the standard thing to do is to mount it sideways, let it stick out, and install the dummy engine on the other side.
Once it's airborne, you'll never noyice it (Unless, of course, you're a real scale buff)
Looking at Rednecks original question - Which was, "Which Cub BUILDS the easiest" I would recommend the Goldberg.
Build-wise, it's on a par with the GP, but I think it's a notch up when it comes to flying
