Hey Guys,
I've seen it set up where a string is tied around the nose, string goes up to a hook on the ceiling and back down and tied to the tail. The plumbob is set at the hook at the ceiling and hangs down to the top of the fuse. Now do I set the pitch attitude of the jet to "0" pitch/incidence and read where the plumbob points (CG)?
Is there a ballpark recommended distance from the plane to the hook vertically?

Is there any link at all to this method of locating a CG with a diagram??
Any help would be a big hit. Jet is a JL hawk to be balanced.

Thanks guys,
Mike

I think you are referring to the pendulum method......slightly different that what you discribed. you need a longitudinal bar so the airplane can tip back and forth until it is stable.... a plumb bob (or in this case, a handy screw driver) will point towards the cg....

Try this:

Thanks Wayne,
The pic you show seems a little more accurate with the horizontal bar than what I've seen (less resistance in pitch attitude).

Spar, Thanks for the link! I have a clear idea now of the mechanics on the set-up.

Thanks guys
Mike
