The day came, what does she weigh?
First the task of getting it in a flight attitude, on scales, and balanced. Fortunately, Scott was along to help and give advice. Everything in is, cowlings are on top of engine, fairings are taped in pace.
Once she was in, I sat back and took the readings. Then Scott says ok lets go, got to move the scales. Move the scales? Well it turns out in the real aviation world of Delta, they move the scales around and take average readings due to the inaccuracy of the scales. UGHH!!!
So we did. As it turns out, there was a serious difference between scales. Here is my chart. Scales on 3 readings showed 20lbs difference. WOW!. Numbers shown here are from the average readings.
