I am one of the guys who responded "over there". Some of us have chosen to extend the wingspan by not clipping the ends of the LE and TE pieces. If you do this you will need to make some modifications to the center section, four additional ribs, and new fixed flap pieces.

The rest of mine is box stock. Here is a comparison. The lower one is standard powered by a slant plug Fox .15, the upper one has extended wings and is powered by a Thunder Tigre .10 CL.
