I went with 20 inches per Joe Horton and several other recommendations derived from KR-2S operations. My aircraft is a stock KR-2 with Diehl tri-gear and Diehl wing skins. I measured the cg on my airplane using digital scales while climbing in and out, and also using sand bags to find the moment and tipping point. I could easily make the aircraft tip with less than my full 200 pound weight trying to climb on or off with the wheels at 17 inches. After playing with those data points on my Excel weight and balance spread sheet, I verified that 20 inches would be the optimum number. My KR-2 is still on the jack stands waiting for other changes. These wheel location numbers have not been tested in operation on my KR-2 yet. Your results may vary.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA -------------------------------------------------------------------------------- I'm about ready to drill my landing gear legs. Are we still at 20 inches aft of the leading edge for a tri gear? I just want to confirm. This is not a mistake that I want to make.? Paul Visk Belleville Il 618 406 4705
