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 lbs Right Main 325 lbs Nose wheel 259 lbs Datum measuring point: Front side prop Crush plate Datum to nose wheel: 21.5" Datum to Mains: 67.5 Datum to leading edge stub wing: 46.5 Datum to Pilot: 65" with pilot weight 178l lbs Thanks for any help.
