You can’t do your “own work on” an experimental glider anymore than you can do on a type certified one. Either one requires an A&P or a Repairman to sign it off. Except for preventative maintenance which a rated pilot can do in either case.

As an EAA technical counselor, I can say that that's almost always wrong. The operating limitations attached to the airworthiness certificate have the final say, but in all cases I've ever checked, there are no limitations about who can work on an amateur-built or racing experimental aircraft; 14CFR43 does not apply to them. The only thing you need certification for is signing off the annual condition inspection, and that's what requires the Repairman Certificate or A&P rating.
