Default Bridi 4 Seasons 40 CG location

A friendgave me an old 4 Seasons 40 that I trained him to fly with in the mid 80's. I got it all setup for flying but it seems t0 be tail heavy. I 'm guessing that the CG location is on the wing spar? Anyone have a set of plans for this old plane?

Is the wing straight chord or is it tapered either leading, trailing edge or both?

Jeeper, if it's a constant chord, put the CG 30% of the chord behind the leading edge. If it's not, use this website. Dan.
