The kit that gave me the most trouble was a Sig 1/6 scale J3 Cub I built. This is a stick built kit and the directions where terrible. The full size plans where just OK. I had to figure out how to do must of the finer things myself. Like how to build and attach the wing struts. This was not a good kit for my second build. It did turn out to be a very good flyer and seems to sign hang there on a windy day.

Thanks
