Applying poly glue

Scott,
Use light wood and no more than 1 pound density foam core. Make sure the  
sheeting for a wing weighs in at around 40 grams but no more than 50 grams each.  
Be very fussy about the sleeve fit into the foam core; glue makes for a  very 
poor filler.The lightest sleeves are probably the PBG glass. I capture  mine 
on the top and bottom with 1/8" balsa spars, full length plus 3 inches,  
rather than with a vertical lite ply piece at the end of the tube. Lighter and  
stronger when finished.
 
 If you don't go hog wild on theglue, the typical 500 sq inch panel  will 
come in at around 8 1/2 to 9 ozs. I use no balsa tip blocks on my wings,  just an 
end plate of lite ply that adds maybe 5 grams. Of course wing panels are  cut 
with that in mind. Lite ply has proven far more durable on inevitable  runway 
scrapes and more accurate than balsa tip blocks since there's no  shaping.
 
As far as removing some of the foam via honeycombing, I've done that too  and 
saved another ounce or so per panel. However at 9 ozs the wings will fly  
great. These will typically finish out at around 12 1/2 -13 1/2 ozs each ready  
for equipment. There's nothing wrong with that weight. If more weight loss is  
desired, one should look elsewhere. There are plenty of places to remove  
weight.
