Leveling the aircraft
Since I have an interest in this product and there is quite a discussion going, I would like to add an opinion.
In full scale applications, which use individual scales such as this product - Leveling the aircraft is critical before taking any readings.
Each (full scale) aircraft has a means of indicating when it is level. It may be a plumb bob hanging in the cabin or inside the tailcone, etc. but we (Technicians) spend a considerable time jacking the aircraft to the level position. My point is, most of our model aircraft don't sit level on their gear, so I would assume shim blocks should be placed under each 'scale' to achieve level.
Personally I would use an incidence meter on the wing to find longitudinal (lengthwise) level.
What am I missing?
