I was helping a friend do a W&B on his RV7A today. We jacked the plane up, zeroed the scales and slid the scales under the wheels. We were having a problem getting consistent results. After scratching our heads for a bit, the builder who had done a W&B on his 6 when he built it remember an important fact; the person who was helping him stated he needed some sort of material under the wheels to allow the main gear to slide outward as the weight was put back on the wheels. We put some heavy weight oil between some pieces of aluminum and placed them under the main wheels. When we lowered the plane back down, the wheels moved out about an inch on both sides and low and behold, we got consistent results.
If you are using ramps to get the plane on the scales, you will not require these slip plates.
Hopefully this info can eliminate someone else from experiencing the same problem we were having.
If this a repeat subject, my apologies.
