I had ordered some 48" lenghts sheets from balsa usa. Not very light, but not bad quality. These sheets are for the center section, but only from the CG forward to the LE, to help with the strength of the wing and the weight of the engine nacells. I am going to buy the rest of the sheeting from lone star balsa. The 4 - 7 lb bundle and AAA bundle. I want to keep this model light. Around the 15 lb mark. 12 lbs would be better. I'm also using only on the center section .6 oz glass cloth, everywhere else will get the .5 oz glass cloth. All 1/4" ply will be replaced with 1/4" composite end-grain balsa panels. ie, fire walls and wing mounts. This stuff is 1/2 the weight of 1/4" birch aircraft ply. I like to build light but also strong. If I build too lite, I can allways add balast weight. If I build too heavy, I'm stuck with it.

Thanks,
Gunny
