I have read quite a few posts about adjusting the CG, setting it nose heavy or tail heavy for certain planes, etc. I am in the process of mounting a small video camera on my NexStar. I have also removed the AFS module, and changed the receiver. When I go to check the CG, what (or where) exactly shoul I be measuring 'level'. The CG balancing points are clearly marked on the wing, but that is the CG pivot point, do I check the bottom of the wing? the bottom of the fuse? Rear stabilizer?
There are quite a few places that could be checked, and I just want to make sure I get it fairly close before I take it out with my instructor for it's maiden flight.

The level of the stab would be a good place to start, or the wing saddle, if it's a flat bottomed wing.

Or, just stand off a ways and see if it looks as if it's "level"!

Pettit is right on. It's usually just done by eyeball, "looks level? yeah, looks level. Ok, let's fly". It's really not a high precision thing at all.

It's usually taken to be the center line of the fuse, and like Pettit said, the stab is a pretty good bet.

And if you're uncertain as to whether it's exactly level or not. the rule of thumb is, it's better to be sitting 1 or 2 degrees nose down, than nose up.

Once you have flown it, you can tweek it from there. If it won't slow down on landings, you may want to shift some weight back. If it's too sensitive to the elevator, shift weight forward.

Great responses all! Thanks a million!
