4. Cyclic Response (Default 100%)
Higher cyclic response will result in a more aggressive
cyclic response.
Lower cyclic response will result in a less aggressive
cyclic response.
5. Tailrotor P Gain Adjustment (Default 100%)
Higher gain will result in greater stability. Setting
the gain too high may result in random twitches if
your model has an excessive level of vibration. High
frequency oscillations may also occur if the gain is set
too high.
Lower gain may result in a decrease in stability. Too low
of a value may result in a less stable model particularly
outdoors in winds.
If you are located at a higher altitude or in a warmer
climate, higher gains may be benefi cial—the opposite
is true for lower altitude or colder climates.
Entering Gain Adjustment Mode
1. Lower the throttle stick to the lowest position.
2. Power ON the transmitter.
3. Install the fl ight battery on the helicopter frame,
securing it with the hook and loop strap.
4. Connect the battery connector to the ESC.
5. Place the helicopter on a fl at surface and leave it still
until the orange receiver LED glows solid, indicating
initialization is complete.
Adjusting the Gain Values
If you are using a Spektrum
ter, the gain adjustments can be viewed on the Flight Log
screen. Refer to your transmitter instructions to locate this
screen. The gain parameter currently selected will fl ash

Once you have entered Gain Adjustment Mode, move the
cyclic stick right and left to select the gain parameter to
adjust. Moving the stick right will select the next parameter.
Moving the stick left will select the previous parameter.
The selected gain parameter is indicated on the Flight Log
screen above and by the lean of the swashplate on the roll
axis as shown in the table at the right.

6. Tailrotor I Gain Adjustment (Default 100%)
Higher gain results in the tail remaining still. If the gain is
raised too far, low speed oscillations may occur.
Lower gain will result in the tail drifting in fl ight over time.
If you are located at a higher altitude or in a warmer
climate, higher gains may be benefi cial—the opposite is
true for lower altitude or colder climates.
7. Tailrotor D Gain Adjustment (Default 100%)
Higher gain will improve the response rate to your inputs.
If raised too far, high frequency oscillations may occur.
Lower gain will slow down the response to inputs, but will
not have an effect on stability.
8. Tailrotor Adaptive Filtering
Higher gain will reduce oscillations during high speed
fl ight and when using large amounts of collective.
Lower gain will improve tail performance but may lead
to tail oscillations.
6. Move and hold
both transmitter
sticks to the bot-
tom right corner
as shown.
7. Press and hold the bind/panic switch until the swash
servos move.
8. Release the sticks and the bind/panic switch. The
model is now in Gain Adjustment Mode.
9. Proceed to Adjusting the Gain Values to make any
desired changes.
on the transmitter screen. If you are not using a Spektrum
telemetry-enabled transmitter, the parameter and gain
values are indicated by the position of the swashplate on
the helicopter.
