3. The sound from HP II is
more concentrated in a narrow spectrum which makes it easier for ANR headsets to
cancel but sound pressure readings in the cockpit are a good 5 - 8 db
higher.
This is bad. I like
quiet airplanes. Not so much from the pilots point of view but from the ground
observer. Too many pot-smoking beatniks trying to get aircraft banned from
parks up here.
6. The airplane is frighteningly fast
due to 4 & 5. Could not do an all out top speed run due to
airframe concerns. I backed off when airspeed exceeded Vne by 10
mph.
This is very good! So
good in fact, that I can almost forget about #3 above :-). I can't wait to hear
about the results of the Sun100 race.
Inspection of the spintech internals (easy to see through the inlet) showed
it was in perfect condition after ~ 300 hours.
The SpinTech design seems
to be pretty tough. Even my own homemade version looks as good today as when I
built it. ~30hrs.
