Hi Paul,

Very interesting data from Al on his 20b velocity. Thanx Al, could you
answer some questions?

1) What was your altitude during your 200 KTAS hi-speed run?

2) Do you use any sort of MAP enhancement? (ie turbocharge, supercharge,
nitros oxide, etc)

3) If you do not boost, are you using the stock rotors or some higher
compression rotors?

4) Your max speed is at engine rpm 6450, apparently you use the 2.17
gearbox, is the box ratio turning the prop at max acceptable rpm and
stopping you from turning the engine faster? In other words if you had a
3.xx g'box ratio would you turn the engine faster or is there some other
reason you limit yourself to 6450 rpm?

Thanx again, Al, for all the good info.                               Dave M
