For your information, recently we asked Rick = Schrameck,=20 president of Aero Supercharger Solutions, LLC., if he would flight test = our=20 3-bladed, constant speed AeroComposites propeller (72 inch diameter) on = his=20 supercharged Lancair Legacy aircraft which he agreed to do.

During all = flight tests=20 there were two pilots on board, takeoff was with full fuel load with 50 = lbs of=20 baggage on-board. The gross weight of the aircraft during test was 2420 = lbs at=20 takeoff where the dry aircraft weighs in at 1440 lbs. The flight test = results=20 reported to us by Rick are impressive.

With our propeller, Rick reported a shorter takeoff = roll, a=20 climb rate of 3100 ft/min from 3,000 to 15,000 ft altitude at constant = 160 knot=20 airspeed. This represented an increase of 1100 ft/min in climb rate for = his=20 Legacy. At 15,000 ft altitude, the high speed cruise was recorded = to be=20 345 mph, which Rick said represented an increase in cruise speed of 21 = mph for=20 his aircraft at that altitude.
