 Here is the first balsa HLG I've made in maybe 20 years. 17" wingspan, 10 1/2" LOA . Main wing is  3/32 soft balsa, canard and vertical fins are 1/16 soft balsa, fuze is two laminated strips of 3/32 medium/hard balsa. It weighs 13 grams all up. I designed it with the TLAR method, and It was just a whisker off in CG, I only had to add the tiniest dab of clay behind the main wing to get it trimmed out. Since I only had shellac on hand, it's sealed with a single coat of that thinned out. I need to get some good brushing lacquer or dope for the next ones. It flies flat and slow out back, haven't had a change to take it to an open area and let it rip yet. I think this basic config might make a good cat launched plane.

Put a hook in the nose!!

Exactly where did the CG wind up.  Always interested in canards.

 CG is about 1/2" back of the leading edge at center. I probably could have sanded more off the nose to bring it to trim, it was that close.

A very pretty aeroplane but I suspect you will need a lot more distance between the main wing and the foreplane for successful catapulting.  Like Flydean I await test flights with interest.

 Hi John, could you elaborate on that a bit? What might be the issues with this configuration on a cat launch?
