Don't know about the Troublemaker (I've heard about it, but never seen it or flown one), but I do know the Miss Norway. I flew one from a fellow club member back in 1979 or so, and if I recall correctly, I think it was a swept wing design. RCM has the plans and there is a photo there also (looks swept wing there also, but from the angle of the photo, I can't confirm it).

Take a look; you might want to purchase this one from your friend also. If not, then I would be interested in purchasing it, if the price is reasonable.
