Converting a USA C of A from Standard to Experimental

New forum member, glad I found this resource!

I'm in the midst of purchasing an ASW-19 that has a Standard C of A...and am mulling over (because of some of the projects/instrumentation/maintenance/etc) if it would be beneficial to convert the certificate over to Experimental.

If the conversion is possible:

1. How much of a hassle was/is it?

2. Was the conversion worth the effort or are the FAA requirements onerous?

3. How difficult would it be to put the genie back in the bottle (go back to Standard) if needed?

4. Who do I talk to at the FAA to accomplish this and what's needed in the way of paperwork?

5. Anything else to make me smarter on this topic?

I tried to search this forum for the answer, but only found topics about going from Experimental to Standard. If there is a thread out there that covers "going the other way" a link to it would save typing and be much appreciated!

Thanks,

Rob S.
