RE: Magic 60
The one I built from a Hobby Barn kit would pitch down badly in knife edge. It would do about a 250' circle without corrections. I changed the incidence of the wings a lot and moved the CG and it got better, but I never flew the model in a contest.
I think their were Magics, and then there were Magics. I have heard the ones built from the MK kit were good fliers. But I never saw one from a Hobby Barn kit fly well.
