I started by completely stripping all covering. Had to use dope thinner to get all the film glue off. It sure was not MonoKote. The covering’s glue was very sticky and had the pigment in it. It was a bugger to get it all off.
I removed all the control surfaces, as I intended to replace them with larger ones anyway. I also intended to install flaps.
After clean up I enlarged the vertical both wider and taller, and a bigger rudder.
New elevator, bigger.
Made wider ailerons but only the last halve of the span. Flaps inboard of them.
It should be rather quick on the controls. But that is what expo is for.
New wingtips, the original were plastic and badly cracked.
The wingspan is now 54. 12” inch chord. 648sq” of wing.
