3top, if you want to get down quick then just roll inverted and pull, it always worked well in the Lynx!!! Seriously you must ask why you would want to fly at 100 kts in auto as any increase in speed above the recommended auto speed for min RoD brings with it an increase in RoD - at 100 kts in a robbie your RoD would be very impressive and would probably not take you as far as if you were at 75 kts and 90%Nr.
