The original Firestar never had a 7 rib wing. That came along with the KXP and the Firestar II, probably around 1990 according to the Kolb website

As I recall, Kolb had a test pilot go up and intentionally break the wing on a Firestar by overspeeding it and doing a sharp pull out. They recovered the wreckage with a ballistic chute, then strengthened the parts that broke.
I may be hallucinating again, but this is what I recall. I'd have to drag out my old copies of Glider Rider from the attic to confirm.

That did happen on the Ultra Star.... some young and crazy guy(Dennis
Souder) flew the US to the point of structural failure...The drag strut
came out of column and required some beefing up..as is seen on all Kolb
wings today.. Herb

Don't believe Dennis Souder intentionally flew/tested/stressed the US to
destruction, but he did accomplish it. The goal was to prove the aircraft
would tolerate the advertised G loading of, I think, 4+/4-. Dennis exceeded
advertised g loading, I'm guessing 5+/5-. Decided to see what it would do,
when a drag strut failed.
Dennis was flying with a hand deployed parachute, not a ballistic parachute.
I hadn't covered the wings of my Ultrastar yet. Kolb Company sent me the
drag strut braces, 31 years ago this March.
When I built my Firestar, I installed a G Meter, later installed in my
MKIII. Was very difficult to pull 5 G's with the Firestar. Most aerobatic
maneuvers could be performed pulling 2.5 to 3 G's. My MKIII has never
performed an aerobatic maneuver, but has pulled a lot of G's, positive and
negative, flying in severe turbulence.

At one point I had a video of of Dennis Souder doing aerobatics in a Kolb. Very impressive.
Dennis told me later on the Homer Kolb sat him down and said Dennis you don't need to be braking any more of our factory planes we have a new customer that is intent on pushing the limits of our planes. Seems like he said it was John Hauck.

Homer Kolb often told me I was his best "test bed".
The factory did a lot of testing, but I don't believe they were able to put the hours and loads on US and FS that I was able to do. I loved flying both these aircraft and flew nearly every day. Both aircraft flew long cross country flights, heavily loaded, through a lot of adverse weather, made thousands of landings on all types of fields, mostly rough unpaved strips, and a lot of aerobatics.
I broke both my airplanes while flying. Both were scrapped.
I learned stress was cumulative. Every time the aircraft is stressed, a little bit is subtracted from 1.0. Eventually, you will ask it to do a job and it will respond with a failure.
I was lucky, was trained to use parachutes in the Army, was a paratrooper 9 years until I went to Army flight school to fly rotary wing aircraft. I knew parachutes worked, I trained for a catastrophic failure, should it happen. I used the same hand deployed parachute twice, I practiced deployment every time it was repacked. My Brother Jim repacked my parachute one week before I used it the first time. He sat me on an air conditioner unit and I actually threw the parachute down and to the left, same as I would, should I need to.
I paid $500.00 for a Jim Handbury Hand Deployed Parachute. Best $500.00 I ever spent. Saved my life twice at 250.00 a pop.
Getting a little long winded here. Search the Kolb List Archives. I think there is info on the cause and save of both aircraft, and me.
