I don't know if it got through but I calculated 56.07"... Assuming his station measurements and weights are correct.

What are you getting for a calculated CG for the aircraft in flying configuration? I would hope that it is 54.5 to 60.5 based on your Datum for your leading edge.On Wed, May 20, 2026, 10:05 mark jones via KRnet <[email protected]> wrote:--HELP......I am so confused. My new KR WunderBird is ready to fly except for the weight and balance. I have made many runs down the runway and on one run I lifted the nose and she shot straight up to about 100' and I could not push the nose down and she stalled on me. I was fortunate enough to cut power and get her flat before she contacted the ground very hard. Bent the main landing gear brackets and had to make more. I did some w&b adjustments, repaired the gear and tried again. Still tail heavy. I am very lucky I did not destroy the plane on that first flight attempt. So, here is my challenge to anyone who wishes to figure a weight and balance on this bird. I just want to compare others with my calculations. Here are the parameters.Weighed with FULL FUEL: 12 gallons each wing.Left Main 319 lbsRight Main 325 lbsNose wheel 259 lbsDatum measuring point: Front side prop Crush plateDatum to nose wheel: 21.5"Datum to Mains: 67.5Datum to leading edge stub wing: 46.5Datum to Pilot: 65" with pilot weight 178l lbsThanks for any help.
