Gain Adjustment
The main Forward Programming displays fl ight control adjustments under
Swashplate and Tailrotor.
Tip: Adjust gains per fl ight mode by setting the Setup FM Channel:
Function in the setup menu. Set the Channel Input Confi g in the transmitter
for the selected channel to Flight Mode.
After the tail gains are fairly close, use the transmitter gyro gain function to
adjust the gain for each fl ight mode.
1. Cyclic P Gain Adjustment (Default 50%)
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 will result in less 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.
2. Cyclic I Gain Adjustment (Default 50%)
Higher gain will result in the model remaining still, but may cause low
frequency oscillations if increased too far.
Lower gain will result in the model drifting slowly.
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.
3. Cyclic D Gain Adjustment (Default 7%)
Higher gain will improve the response rate of your inputs.
If the gain is raised too much, high frequency oscillations may occur.
Lower gain will slow down the response to inputs.
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 85%)
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.
