Nick Smith, used to have the Smith Supercub Kit. At that time Wayne Axelson was building the wings for Nick‘s kits. They were very well-built, perhaps a little on the heavy side, but true and accurate wings.
When Nick sold his company to Turbine Cubs of Wyoming, which was later to become Backcountry Cubs, Wayne Axelson went and worked for Backcountry Cubs. After a couple of years Wayne left Backcountry Cubs and returned to Canada.
I do not know if Nick is building his own wings now or if Wayne has resumed building them since he is no longer associated with Backcountry.
either way, I am quite confident that the wing is very similar, to what Nick and Wayne used to build. Like I said, it is quite strong, a little heavy, but a true and accurate wing. The only downside will be the weight. Probably about 15 pounds to 20 pounds heavier, per panel, than a stock wing.
This is just my opinion and I may very well be wrong. Perhaps someone else will chime in with better, or more updated, information.
