A friend picked up a used Monarch. V-tail only, no flaps, wooden wing tips.

Can you advise on best location for CG?

Wow! That's a really old one, either a '93 or a '94. The 'C' came in '96 and had wood-skinned wings with fiberglass tips. The 'D' and Wizard had glass-skinned wings, and the later versions had a closed saddle for the wing and tail, with the tailboom on top of the vee instead of on the bottom. If you can give me the serial number (written in the bottom of the fuselage under the wing saddle), I can probably look it up in the old shop logs and tell you exactly when it was laid up, what version it was, who made it and the serial number of the mold it was pulled from.

It took some major archaeology, but I managed to find a copy of the plans drawing for the '94 on my old 486 computer that I could import into the old DOS version of CadKey. It shows the C/G at 2 11/16" to 3" aft of the leading edge at the root.

Most of the later versions were close to that, typically 2 3/4" to 2 15/16" aft of the root leading edge on the 'D'. In general we found that all versions liked to have the C/G near the aft end of the range, typically the 2 15/16" number worked about the best for Joe and I.
