Give a call to Tom Dixon, it is his design, if we are talking about the same airplane. I have a model called Charmer by Walt Brownell that was built from Charisma plans and that he said he made some changes to, but I don't know what those were. Hard to believe but that may be approaching 30 years ago.
Some where along the line we need to call an end for the Nostalgia 30 class. We are getting to an era where almost any model design can be competitive today. There is almost no point to it.
Type at you later,
