LT-40 CG location

My friend is refurbing an old LT-40.

Without a drawing or manual he needs the design
CG location... inches behind the leading edge.

I would appreciate any help

LT-40 CG location

Hey Ed,

"aerobat66 [C.G.] 3.5" - 4.25" behind leading edge of wing. Mine flew it's maiden flight yesterday, with the C.G. at about 4", and it was fine. I had about 3/4" of elevator throw (manual recommends 9/16"), and it was fairly pitch sensitive."

This is from a previous post from aerobat66 about the same question on the lt-40. Hope this helps

This from a previous post of mine.

Looks like the range is 3 1/2" to 4 1/4" from LE.
