Say WHAT ? 4 different vendors I know all use plastic.


I usually have to ask for some big guy with huge arms to put
the pins in. There must be some secret to this step.

It's very, very technical:
Line up the wings prior trying to insert the pins.
Look inside the holes and make sure they are lined up !
Adjust by height of fuselage and/or wings.
BEFORE trying to jam in the pins.

These tools are only useful if the wings are close
to properly aligned, and especially to pull the wings
together the last little bit.

Hope that helps,
Best Regards, Dave

PS: Use of incorrect grease (or none, or dirt) will
also make inserting the pins extremely hard...
