I’ve long been suspicious of the current cat 1 record. Must have been VERY thermally in that site. Or...something. I would love for someone to come forward who actually witnessed the flight.

As a point of reference Jim Clem held the cat 1 record for much of the 1985-1995 period. We flew together often. Site was Bedford Boys Ranch in Texas, an excellent Cat 1 with peak height just a couple inches below the limit and very good air in the afternoon and evening (there was no cheater hole inside the 15M circle, though). Using black rubber we set Open and Senior records on the same night in 1990 of 9:55 and 9:56. Several years later and using Tan II Jim upped the Open record to around 12:15 if I recall. I remember thinking at the time that 12:30-13:00 would probably stand forever if anyone could do it. Then the Warren Williams time of 16+ came in from the west coast and blew our minds. Still don’t understand how it was even possible.

RIP Jim, a truly great man. Btw his son Mike has returned to FF and will be at the Indoor Nats in a couple of weeks!

I've yet to see anyone else come anywhere close to the Cat I record. Not only that, the plans for Skipper are missing several important pieces of information which render the model effectively impossible to replicate (Prop pitch, airfoils, incidence).
