RE: Build Thread: New QQ-Yak 54 101", DA-85
Front pin from wing root to the center of the hole should measure 10.5mm. This is very important that you make correct measurements. I won't worry if you did 11mm but if you do less that can become a problem!
Rear pin should measure 8mm from the wing root to the center of the hole.
Here's what I did.
I measured this with precision ruler on my desk and marked it so when I apply epoxy to the holes and insert the pin, I won't have to worry about making measurement while epoxy is setting. I use 5 minute epoxy so I need to be fast on this as it set in 2 minutes if you work in a garage at 120 degree LOL
Anyway, apply a little epoxy to the root hole just a layer. Apply more epoxy to the hole on the second rib. Actually fill up the hole with epoxy! Insert the pin so the hole is vertical just like the pictures.
Then mix some micro balloon epoxy and make fillet around the hole on the second rib.
After all that is completely set you can hit it with some thin CA but I won't worry about it if you didn't. Just make sure that you DO NOT apply CA to epoxied area while epoxy is still setting! They don't get along very well!
