I have a KR-1. Last summer I built a set of folding wing brackets, similar to the design presented, out of aluminum U channel. My design involved removing the wings then installing the brackets and reinstalling the wings on the brackets. You need a longer bracket at the aft than at the front of the wing if you want the wing truely perpendicular when it's vertical. The wings tend to rotate toward the tail when they're vertical, so the brackets need to account for that rotation.
I can safely say that the wings will touch above the canopy. I ended up putting some padding on the canopy that keeps the wings apart. Also, something to consider if you're storing the plane outside is that the wind will blow the wings down if they're not secured in the vertical position. I ended up running a tie-down strap around the wings through the aeileron slots and then to the wing spar anchors. Hope that helps. -- Lance
