I have one that I bought off the other stunt site that had all the covering removed( I called it nekked) covered it with silkspan and dope, started out with a Brodak 40 on 58' lines, also had a Fox 35 on it.
I like the way it flies. To be such an old design, it still flies very well..
But 58-59' line seem to work best, and keep it light.. (40-43) oz...
