6. Tailrotor I Gain Adjustment (Default 95%)
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 10%)
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.

SAFE Technology
Always complete test fl ights and gain adjustments before enabling SAFE
Technology features.
Before enabling the stability feature, test the
operation by activating SAFE Panic Recovery
function in fl ight with the transmitter sticks
centered. The model should return to within 4
degrees of level.
NOTICE: High levels of vibration can lead to attitude estimation errors.
When SAFE Panic Recovery is activated, if the model is outside of 4 degrees
of level, evaluate the model for vibration and, if necessary, perform the
calibration step.
The SAFE Panic Recovery function is activated by setting up the following mix
within the transmitter:
Mixing
P-Mix 1
To activate the SAFE Panic Recovery function, move the collective stick to the
center position and press the bind button (switch I) on your transmitter.
The SAFE Stability function can be enabled within the forward programming
SAFE menu. All gains, fl ight mode setup, envelope and gain settings are avail-
able within the SAFE menu. To enable or disable the stability function per fl ight
mode set the FM Channel to the appropriate channel within the Setup menu.
