Re: Wooden repair
When Ken built N34KP he used the Superflite covering system, whichever version it was in the late 90's. I've been on their site and they also have a 2 part epoxy varnish. I'm not sure what Ken used to varnish the structure of his Piet. When I was removing the finish in the repair area (with a block ...

On the weight and balance aspect. When finishing Ken Perkin's piet it turned out to be tail heavy. Not wanting to tilt the wing back we moved the engine 7 inches forward by extending the mount. It's work well for over 18 years now. I also think it looks better.
