A good source for answers would be the Experimental Aircraft Association
(www.eaa.org). They are very on top of the issues of certifying experimental
and homebuilt aircraft...owner and non-owner built...paperwork
requirements...and more.

You might ping this group about what you bought...type of glider etc. You'll
get a slew of opinions on what to look out for and what you may need to do.

And, be sure to visit the homebuilt glider website:
www.sailplanehomebuilders.com

Bought a built experimental powered glider and All I have is a bill of
sale from an individual who is not the builder and does not know who
he was. No data plate, plans or other documentation with kit number.
Is there anyway to satisfy the FAA's chain of ownership requirements ?
It only needs a sprucing up and some minor repairs to be flyable.
