Resetting Stick Neutrals (Toggle) - Lemon RX Instructions Manual

Lemon RX Stabilizer PLUS Receiver – Essential Instructions
Toggle Gesture
Move the Stabilizer Mode switch on your transmitter back
and forth as quickly as possible through its full range for at
least 2 seconds. This procedure applies to both 2- and 3-
position switches. At a minimum the stabilizer needs to see
six changes of switch position (see diagram) within 2
seconds, but a few more changes are desirable to guarantee a
successful reset.
To reset level as seen by the stabilizer:
1. Set the model up in level flight position on the bench.
2. Turn on the transmitter and apply power to the receiver (bind plug not required).
3. When Indicator 1 (Green/Blue) starts flashing, immediately (within 8 seconds) perform the toggle
gesture explained above, flipping the switch back and forth continuously for 2-3 seconds.
DO NOT MOVE OR DISTURB THE MODEL during this step.
4. After 2-3 seconds, the Red LED of Indicator 2 should come on for a few seconds. After a further wait,
the Green LED of Indicator 2 should flash four times to confirm initialization.
If you do not see this confirmation, repeat the process until you do. This is necessary to ensure correct
initialization. A possible reason for failure is movement of the model during initialization.
5. Power down the receiver.
If you observe any unexpected responses from the model, on the ground or in the air, perform a reset as
described above.
If you perform this procedure, it's REALLY important to verify that the "toggle gesture" is successful, as it
resets the Stabilizer's orientation and Autolevel values. Be sure you see four Green flashes on the
Indicator 2 LED (near the pins). No flashes = no fly!
The Stabilizer retains the values generated, so the procedure does not normally need to be repeated unless
you want to adjust the Autolevel attitude or you change the stabilizer's position in the plane.
Also, don't forget to also reset the stick neutrals, as described in the next section, as they can have an
important impact on the model's behavior.

Resetting Stick Neutrals (Toggle)

To ensure optimum stabilizer performance, after any major adjustment of the trims or subtrims it's a good
idea to use the toggle gesture (as defined above) to reset the stabilizer's values for the stick neutral
positions. This is an entirely separate process from resetting level and can be done at any time after the
stabilizer has completed its initialization, even in flight. During the reset, the aileron, elevator and rudder
sticks and the corresponding trims must not be moved.
With the transmitter and receiver ON, and leaving the sticks and trims untouched, move the Stabilizer
Mode (Gear) switch as quickly as possible back and forth for at least 2 seconds.
The Stabilizer PLUS performs best, especially in Autolevel mode, when trim and subtrim settings are kept to
a minimum. Where possible, use mechanical adjustments to eliminate the need for large trim offsets.

The model may need to be a few degrees nose-up to maintain level flight at a normal throttle setting.
