Hello Matt,
The five hours of test flights is a formality. You can see the details in my Airworthiness Certificate (six page document) on page 3 article 19 in the airworthiness folder on my Google drive.
In the same airworthiness folder above, I included all of the docs that I sent to AIC, a third party company in OKC that helps the paperwork process along. The use of this type of company isn't required but they know what the FAA wants and can help avoid silly paperwork delays. Their fee is worth it.
I recommend that you get in touch with a DAR, Designated Airworthiness Representative, soon so you know what he/she expects. Since you live in the northwest (I think?), Lynn Wyman would be a good contact to learn about his DAR experience. The DAR will need to see your glider but you also need to get a Condition Inspection from a different mechanic before the DAR visits with your glider. The DAR can also give you advice on the paperwork timeline. The DAR will expect you to have the FAA registration related paperwork done before their visit and this can take a few months. One of the first steps involves reserving an N number.
In the event of a Houston/Galveston delivery, I think that we already discussed the use of DAR Chip King in Uvalde. Here is his contact info again:
