Rubber bands?
My LT-40 ARF wings were bolted on with two nylon bolts.
I think the kit LT-40 uses rubber bands.
Don't think you need them unless they're for something other than wings.

The original run of LT-40 ARFs used rubber bands. Current run features bolts. I got an email from Sig saying they found a stash of early LT-40 ARFs (w/rubber band attached wing) in their warehouse and were offering them at a steep discount.
