Stability in Pitch- Step function improvement, 10-15 % increase
Stability in Roll- Step function improvement, 10-12% increase
Stability during roll entry and exit, 5% increase
Stability during and after stall turn- 20% increase
Stability leading up to a Spin entry 5-7% increase
Stability during rolling loops and circles- 3%-5% increase
Amount of up rudder- to up-elevator mix- 2% decrease
Slower speed on down-lines 3% decrease
25% less rudder deflection needed during point rolls (but see stall turn below); from more lift of center of fuselage.
75% less wiggle during entry and exit of rolling maneuvers, and correspondingly reduced fuselage deflection during rolling maneuvers. (fuselage deflection with respect-to-track of aircraft)
Drag to top of aircraft during maneuvers- 1% increase resulting in 1/4 degree additional down thrust required, and 3% more down elevator to low throttle mix on down lines (at 67% offset)
Additional rudder inputs needed for stall turns- 15% or more, particularly near center-stick.
Additional rudder needed during first 15% of rudder stick movement during rolling
25% more throttle-to-rudder mix during down lines (an additional 2 % mix) and 1/4 degree more right thrust on up lines required.
More control inputs during rolling loops and circles (as a result of less fuselage deflection with respect to track of aircraft) This was most surprising.
All findings are preliminary.
