Yes I'm using douglas fir and the weight is not that great,to figure the difference you just figure total weight ofwood used probabaly not over 175 to 200 lbs now figurethe difference by calculating the cross products of a proportionsare always equal.spruce= 28lbs per sq.foot total weight of fuselage,tail,wing =200 lbsdouglas=33lbs per sq. foot total weight of fuselage,tail, wing=unkown33 X 200=6600 6600/28=235.7 you probably could cut down on dimension example=longerons from 1"x1" to 1"x7/8 and get the weight dwon to the same as spruce----- Original Message -----

I'm using a steel tube for my 'stick'. I plan on turning a wooden handlegrip out of cherry for the top two grips.Looks great and isn't all that hard to do. Lasts longer than the foam orplastic grips.I made one for my Kolb ultralight and it worked well.Greg YotzFit wings and control system. Looking at fabric.....-----Original Message-----
