Are there still any line contorl model pilots?

[Bill Greenwood]

When I was a kid there were a lot of flying model planes and some were a lot of fun.There were a few soaring gliders, a few free flight models, but most were line control or U contrtol where the pilot stands in the mddle of the area and the plane which is on the end of a fine line flys a circle around the pilot , perhaps 100 ft radius. The line is connected to a U shaped device so that as pilot tilits it up you get up elevator and tilt down for the opposite. Some of these are pretty sensitive especially the fast ones, and they can make you really dizzy quickly. They sound like a real airplane, not an electric one.
I have 2 brand new planes fully assembled, still in the original boxes, never opened, just a little dusty, and I am not sure where is a good home for them. They have some sentimental value to me, I dont want to see them just wrecked, They are COX .049, one is a Spitfire and one a P-51, I think the Red Baron maybe. Im told they are fast , espcially the 51 and therefore need an expert pilot. I have flown a little line control with a basic traineer , but a long time ago and I m not up to these though it woud be fun.
Any offers to buy or otherwise good suggestions? Does EAA still fly the model behind the museum at Pioneer Airport during EAA? These are probably too fast for kids, but might be fun for demos?
