Where to put CG?
 
Hi,
If you could put your CG anywhere you wanted on a fuse where would you put it? Why?
Thanks,

I've noticed that the c.g.s on my fuselages tend to come out just aft of the trailing edge of the wing.

I tend to favor a static margin of about 2-5% [sm=devious.gif]

Use a better grade of tape -
I put my CG's on with 3M and they stay in place ---

I don't put it anywhere I want; I mark where it should be for convenience.

I balance my airplanes at 30% mac with the wing on, and then remove the wing. I then see where the fuselage is balanced and then mark that place.

Why? So I can check the fuselage CG in the event some of the internal components get moved around, or a fuselage mod was made, or I need to deviate from the 30%mac.
