I flew both the regular and clipped wing version of the great planes .40-size J-3 cub kit, and I now have the world models clipped wing cub. I prefer the clipped wing. Although I mostly just cruise around with my cub, the full length wing made me uncomfortable in rolling maneuvers. It just took sooooo looong for the plane to roll over and return to level flight. You really don't need the extra wing area for the plane to fly well or scale-like, and it unnecessarily adds difficulty to transporting it. Besides, the sunburst pattern on the clipped wing cub looks better than the all yellow. At least it's not as common. I say go with the clipped wing.

I flew the GP cub with an OS 70 surpass, which is way more power than needed. I'm flying my WM cub with an OS 52 and a 12x6 prop - also more than enough power.
