One night each wing
two nights for teh fuse
one night for the tail
two nights covering (or more, depending...)
One night to set up, balance, etc...
One night to ensure everytihgn is OK, and set up from teh night before (spread out over the nights..)

8 nights...

It took us about 10 nights for ours... about 3 hours each night. It is a really really easy build!

And...
One night to take the wife / kids out to dinner, to prove you are still there..
