The fuse is fiberglass. The wings are foam, covered with balsa and 55 inches wing span.I believe this is an old CMP plane arf but I don't know. Any spec, control setup, and CG will be appreciated.Also anyone with flight experience feedback would be welcome.Thanks.

Hi sorry I can offer nothing as to the original manufacturer. Even if it was a CMP what little info they had at least as far as CG they were often very poor CG suggestions .
With the almost elliptical wing mid span averaging works quite well. Measure the chord from the leading edge to the trailing edge mid way between the wing tip and the fuselage side, half way out there. Now take this mid way chord measurement and divide by four. this sum is the distance back from the leading edge that will give you 25% MAC or the quarter chord. All that is left to do project this point back from the leading edge half way out there on the wing straight inward to side of the fuselage and this is where you use your balancer or fingers, whatever.
This works very well for most warbirds and the quarter chord is an excellent starting point l for most warbirds.
