To adjust the Throttle Curve and Servo Exponetial turn DIP switch #11
ON
, making sure that #10 and #12 are off. Remember to match your
head speed to how much pitch range you have set; low head speed with
more pitch, high head speed with less pitch.
NORMAL FLIGHT MODE THROTTLE
CURVE ADJUSTMENT:
Make sure that the Flight Mode switch is set to the Normal Flight Mode
position. You will be using the V1 dial to adjust the throttle curve. In the 0
position, the throttle will be at 50% power at half stick. Turning the V1 dial
to -100 will shift the throttle down to only 40% at half stick, while turning
the V1 dial to +100 will shift the throttle curve to 80% at half stick.
3D FLIGHT MODE THROTTLE CURVE
ADJUSTMENT:
Make sure that the Flight Mode switch is in the down position to select 3D
Flight Mode. With the V1 dial in the 0 position this puts the throttle setting
at 60% power at half stick. Turning the V1 dial counter-clockwise to -100
will shift the throttle curve down to 40% power at half stick. Turning the
V1 dial clockwise to +100 will shift the throttle curve to 80% power at
half stick. Running a higher head speed is good for flying aerobatics, it is
more responsive, though you will get shorter flights. Lower head speed is
great for just general flying and getting long flights.
IX. THROTTLE CURVE & SERVO EXPONENTIAL
SERVO EXPONENTIAL:
Servo Exponential adjusts how linear the movement is as you move the
elevator/aileron stick. This is done to desensitize the area around the
neutral position making for smoother flying. It is possible to dial in both
positive and negative exponential. Positive exponential makes the servo
movement less responsive to stick movements around neutral. Negative
exponential makes the servo movement more responsive to stick
movements around neutral.
- With the V2 dial in the 0 position, servo movement is perfectly linear.
This means that if you move the stick half its movement, then the
servo will go half its travel. The VNR 3DXL™ comes factory set with
no exponential.
- Turning the V2 dial clockwise to the +100 position, will give you
positive exponential meaning most of the servo travel will not actually
occur until you go towards the limits of the stick movement.
- Turning the V2 dial counter-clockwise to the -100 position will give
full negative exponential. This setting will magnify small stick inputs
around the neutral stick position. It is not recommended using
negative exponential unless you are a very experienced pilot.
To save the adjustments, turn the #11 DIP switch back to
OFF

pitch at half stick, and full positive pitch at the
throttle up position.
With the V1 dial at the 0 position (12 o’clock) the pitch curve is perfectly
linear. This means that pitch starts to be introduced as soon as you start
to throttle up. With the dial rotated all the way counter-clockwise the pitch
curve is shifted causing most of the pitch to be introduced after the 50%
point of the throttle stick. This is for pilots that want to do much more
aggressive flying. With the dial rotated all the way clockwise, the pitch

curve is shifted causing most of the pitch to be introduced before the
50% point on the throttle stick. The helicopter will lift off the ground very
smoothly as the pitch gets introduced at a much lower head speed setting
while the head is still spooling up.
We recommend as a starting point that you test fly the helicopter with
the factory settings and then adjust to suit flying style or ability. Once you
have adjusted the helicopter, put the #10 switch in the
OFF
position to
save these settings.
