CMP P26 Peashooter. Undercarriage wire. This was redesigned once by the factory after the landing gear legs in the 1st release kits were found to be too flexible.
The Mk 2 design with the added rear brace has gone to the other extreme and ithe legs are now not flexible enough. The current design will not allow the u/cart wire to torque and absorb landing shock. The shock is therefore transmitted into the rear wing mount and causes errosion of the mounting hole in the rear of the wing.
Also, quality control on this same part. The slots/holes for the wire, in each wing, do not match up with the supplied undercarriage wire legs. ( they didn't in the 2 P26's I have anyway.)
So I had to have a friend bend up some new legs and in doing so, we redesigned them to allow the wire to absorb landing shock. A rough diagram is attached.
The inverted "V" shape allows the front leg and the brace to flex back and forth, therefore absorbing shock caused by landing and taxiing around.
