Build up of the tail group...

Finished tail group build up. The kit does not call fro sheeting of the tail surface...but I was a bit concerned with overall strength so I went ahead and sheeted them with 1/16" balsa. Not necessary and weight fanatics won't like it but I prefer a solid airframe over the lightest possible one.

And tail struts are now in...made from streamline aluminum tube from Glenn Torrance models...much heaviere wall thicknedd than KS tubing you find at most hobby shops - this stuff is strong enough to be structural.

I think you did a good thing, that balsa don't weight nothing. And the strength added is significant.

NICE WORK!

Starting the pics for the bottom wing the bottom wing here. With the jigs provided by Jtec it is impressive how quickly these wings come together.

One of the mods I made to the kit is that the plans call for a Python style suared off wing tip. I prefer the more traditional design so I made my wing tips curved like the originals
