I hope he is OK and recovers. I hate seeing people hurt.
High speed taxi's on new airplane designs by professional pilots often reveal flight critical issues before actual flight. Things like good air data, braking efficiency, expected rotation speeds, etc could all prove critical to a heavy, fast, or unproven design.
None of these are critical to most of our homebuilt airplanes. We should have plenty of runway for our first flight so braking should not be an issue. If we lift off and don't have good airspeed data or even an altimeter, it should be no big deal, even to a nervous homebuilder turned amateur test pilot.
I have flown or been involved in over a dozen homebuilt first flights. These things are all briefed and practiced. As a Flight Advisor and CFI, I usually don't recommend high Speed taxi tests. If the airplane and pilot are ready, go to the end of the runway and take off! If you are not 100% confident, do what it takes to be so even if it means getting another pilot to help.
