First flight on my KR-2 was in 1984, built pretty much to plans including the original gear. Did not trust the mouse trap spring down lock latch. Norm Taylor of HAPPY ENGINES came up with the solution. a pin lock quadrant gear lock system. Over the years I had to make other improvements: 1/4 inch steel main gear hinges, and replace the 1/4 inch plate aluminum quadrants with 1/4 inch steel; plus 1/4 inch welded cold rolled plate gear legs.
Almost 1500 hours on the meter and hundreds (thousands?) of take offs and landings does take a toll on the retract system. I can supply copies of the quadrant gear lock system if needed. In closing I have to say that the retract system has saved me from probable injury and prevented serious damage to the aircraft by collapsing during a few excursions off the runway and into the ruff ,and on one occasion into a snow bank.
