You really need to watch the buildup of some of the older CL models. They are not very large, have quite large engines for their size, and very rugged (meaning lots of hardwood and plywood) structures (I'm also talking about a lot of designs from the '50's to late '70's when CL stunt was really popular). There are a few I'd like to convert, but they'll require a complete structural redesign to lighten them up so they will be functional as RC planes.

One plane I'm working on right now is a kit produced by Balsa USA called the Smoothie II (it's been out of production for quite a while now). It's based on the original CL Smoothie stunt ship.
