I have an old Sig Midstar 40 and lost the instructions to it. I need to reset the control throws and balance it out. Does anybody know the specs on it?

I would try calling Sig. I have called them before and they have always been super helpful.

If Sig doesn't get you the answer just set the control throws to TLAR specs. (That Looks About Right. )

As for the CG, you cn use this graphic to figure it out, or just start at about 25% of the wing chord (back from the leading edge.

Here you go, from the manual. These are recommended for test flying. No other measurements are given.

Throws:

Elevator - 1/2" Up, 1/2" Down
Rudder - 1" Left, 1" Right
Ailerons - 3/8" Up, 5/16" Down

I couldn't find the CG anywhere, except for marks on the plans. I measured them to be between 2 3/4" and 3 1/8" from the leading edge.

Hope it helps.

Thanks a lot guys, you were a big help! Now I can get started.
