RE: Checking CG?
Em - and how about a mid-wing? Now, is that a setup or what?
BTW Gene - thanks for the idea of doing a CG test before covering!
Oh yea - I have a problem with determining "what's friggen nose up or nose down" when I'm balancing the plane on my finger tips. One technique that I have found simple, cheap and effective is the use a string level to make sure that the plane is level. I place the level on the horizontal stab and shim the plane on my bench using whatever you have available. This sets the plane at level "flight" because most of the planes have the stab set a 0 (zero) degrees incidence (aka - level). Then when I put my fingers under the wing and lift I watch to see which end drops - front drops - nose heavy. This works whether your plane is upright or inverted.
Yea, I've tried a bunch of "devices" including dowels with erasers and the Vanessa rig. This is pretty simple.
