I picked up a mostly built 40 size stik kit for cheap. I have a couple of questions, if you don't mind.

The previous owner was going to use rubber band to hold the wing on, but he has the mounting spots for bolts, any tips for tapping wood for the nylon wing bolts?

When he cut out for the hinges he mad the openings very large, the ca type of hings very very easily slide into the openings, should I replace with some other type of hinges like pin hinge?

One more question, I am going to do my first covering job in more then 18 years (long break) do I need more then 1 6' role for a 40 size plane for the main covering

I am going to make it a tail dragger or a float plane, anything else I should do when doing the final setup of this plane?

It also came with a older OS 40 SX engine for the plane that needs a bit of cleaning.

Thanks
