Pete1burn... It's been a few years since I put mine together, and it's still together...
But I epoxied all the surfaces... It may not be needed, but I also glassed the wing
joint... I have put a ton of flights up til this day, and loads of stress... And she's still
hanging together to tis day, just about 3 yrs later and 250+ flights

I only glassed the bottom of the wing... Sorry... Here's some pics..
