RE: GP Extra 300S 60size Build
Here's an update what I've got done so far. Put the DB together with epoxy good to go, got the pin anchoring bracket in and glued with epoxy, started the top sheeting - got the back part of the left wing sheeted then found out I am short a 3"x36" piece of 1/8" balsa DANG!! now I have to run to the hobby shop and pick a piece up to finish the right side of the sheeting, so I sheeted the leading edge portion epoxied the spar part and going to CA the ribs like I did the bottom side. Fitted my mid section sheeting to make sure everything works good, so far not to bad.
Most important part I believe is that the dihedral of the wing worked out though I have a small 1/16 almost to 1/8" gap on the bottom side of the wing in the center though everything is tightly joined when I put the dihedral braces in. So, I just made a sawdust+wood glue filler and filled the gap then sanded that smooth, that should do the trick for now. Last pic is my filler job
