GAIN SETTINGS
Basic gain determines the momentary reaction strength of the gyro. The momentary correction exists and plays an
important role in all flight modes except off mode. Basic gain is the basis of all gain settings and it will directly affect the
performance of the gyro in all flight modes.
Before adjusting other gains, you need to get an appropriate basic gain first. In general the higher the gain the harder the
plane will stop after rotation and the more stable and precise the plane will fly. But if the gain is too high the plane will tend
to oscillate at high frequency on the corresponding axis. If too small, the operation and stability will not be so good and the
plane does not stop precisely and overshoots. The gyro will be deactivated completely if you turn the basic gain to 0%.
For the first flight test it is recommended to start with a lower basic gain setting (e.g. 30%) and switch the gyro to normal
mode. In case the plane starts to oscillate in flight then reduce the gain of the corresponding axis. If the control feels weak
and imprecise and doesn’t hold position when stopping then increase the gain, according to this approach, fine tune the
basic gain until you get the best performance.
The lock gain determines the effect of attitude locking when operating in Atti-Lock flight mode. A lower lock gain can cause
an attitude drift of the plane when there is no control command sent from the transmitter during flight. However if the gain is
too large, the plane will become too sensitive and overshoot. A fine lock gain should be able to lock the attitude of the plane
all the time.
The attitude gain is only valid in Trainer mode. It determines the reaction speed of attitude with command stick input, the
larger the setting is, the quicker the reaction and sharper control behavior will be. When operating the gyro in Trainer mode,
the stick input will not be applied to the servos directly. Instead, the amount of the movement of the servos is determined by
the tile angle of the plane and the attitude gain settings. For this reason, you can’t set the attitude gain to 0 or a very low
value, which will lead to a weak control or even losing control of the plane. In the same way, the basic gain and master gain
will also affect the amount of the movement of the servos, so a lower basic gain and master gain are also not allowed when
flying in Trainer mode.
The level gain is only valid in Auto-Level mode. It determines the speed of returning level position when releasing the sticks.
The larger the level gain, the quicker the plane will be brought back to horizontal position. A lower level gain (e.g. 30~50%)
is recommended to let the plane recover to level flight more slowly and smoothly after you release the sticks. If you want to
use the Auto-Level mode as emergency rescue during flight, then a larger level gain may be needed to make the plane
quickly recover to level position when switching into this mode.
The hover gain is only used for Auto-Hover mode. It determines the amount of the correction which will always stabilize the
