Wing pin grease

My observation is that grease makes a difference in reducing lift pin wear from fretting. It’s pretty much impossible to get the wings to fit tight enough to avoid the lift pins sliding in and out of the bearings when yaw forces are transferred between the fuselage and wings. It isn’t much movement, but over time it’s a significant cause of wear. The movement should be reduced as much as possible by inserting shims, but getting to zero movement makes assembly difficult. No free lunch.

Most of the dust is near the ground, you should try flying a little
higher...

Lol! Ive seen dust devils past 10k agl! But as 6K used to say "All I ever find in dust devils is dust"
