Not Vic... but I mentioned it.
After 10 hrs and a few logged items for both flight testing and the airframe, you can add an "Observer Pilot" rather than the "Qualified Pilot" who needs more experience via a points system.
Not too difficult and well explained here by the FAA -
https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_90-116.pdf
The last page gives details, but most of your pilot buddies should qualify.
☐ Have at least a recreational pilot certificate with the appropriate
category and class ratings for the test aircraft, and have received
all necessary endorsements, as required per 14 CFR part 61,
? 61.31, appropriate to the test aircraft. For light-sport aircraft,
have at least a sport pilot certificate and the appropriate logbook
endorsements for the category and class of the aircraft to be
flown, as required by ? 61.317.
☐ Meet the requirements of ? 61.56, Flight review.
☐ Meet the requirements of ? 61.57(a), Recent flight experience:
Pilot in command, in the same category and class as the test
aircraft.
☐ Have adequate vision forward and to each side of the aircraft.
☐ Complete this worksheet prior to the initial flight as the OP in
each test aircraft and attach it to the airframe logbook. When
acting as the OP for further flights in the test aircraft, prior to
each flight you must meet the OP criteria, but the checklist need
not be attached to the logbook.
The next to last page details the flight maneuvers and plane stuff you must sign off on first. They should be no big deal. I'm just waiting for some wind in the cooler mornings to do the crosswind landings bit.
I like the bit about the Observer Pilot must be able to see out. No sticking him/her in the baggage compartment...
