Lemon RX Stabilizer PLUS Receiver – Essential Instructions
10. Make sure you know how to find the Stabilizer Mode switch without having to look down at the
transmitter and that you know how to turn it OFF quickly if you get in trouble.
11. It is recommended that you set up Dual Rates on the transmitter with Low Rate being about 70% and
High Rate 100%. Use mechanical adjustments and/or servo travel (called Travel, ATV or End Point Adjust
depending on the transmitter) to set control throws to those recommended for the model.
12. You may also wish to add 20% Expo, or somewhat more, to soften control responses around neutral, but
keep in mind that stabilization has an expo-like effect.

Your First Flight

1. Power up first the transmitter and then the receiver.
2. Wait 20 seconds or so until initialization is complete, and the transmitter has control of the servos.
3. Once again check the directions of control and of stabilization movement, especially aileron.
4. Set Stabilizer Mode switch (channel 5/Gear) to the desired mode.
5. Take off and climb to a safe height.
If you have a two-position switch giving access only to Off and Autolevel, go to step 9 below.
6. Turn ON Gyro mode (Position 1 on a three-position switch). Expect Gyro mode to cause the model to fly
more smoothly, resist wind gusts, and be somewhat less sensitive to control inputs than with the
stabilizer OFF. If there are any unexpected reactions, immediately turn OFF the stabilizer (Position 0)
and land to trouble-shoot.
7. If you encounter oscillation on any control surface, slow down and land.
down (counter clockwise) 10 or 20 degrees. See the Complete Guide for advice on fine tuning the gain.
8. Switch to Autolevel mode (Position 2). In Autolevel mode, you should find the model much more
docile, with a strong tendency to return to level when you neutralize the sticks. You will still have
control, but turns may require significantly more input and maximum bank and pitch will be limited. To
increase control authority, you can use High Rate and/or change to Advanced Autolevel mode, which
allows steeper bank angles (see page 9). Be ready to switch to OFF or Gyro if you encounter a problem.
9. If the model (with throttle set appropriately) does not maintain level flight, switch to OFF or Gyro mode,
land and reset Stabilizer Level and Alignment and Stick Neutrals, as explained below.
If you are a beginning flier looking to use the Lemon Stabilizer PLUS to assist you in developing your
piloting skills, we recommend enlisting the help of an experienced pilot for the first flights.

Resetting the Stabilizer

Resetting Level and Alignment (Toggle)

The Stabilizer PLUS normally uses default settings when initialized, based on the assumption that the
receiver is mounted upright and level and accurately aligned with the flight direction. To compensate for any
variations, the receiver can be reset by performing a "toggle gesture" during the initialization process. This
is also required, for example, if the stabilizer is mounted upside down or on edge (e.g., on a profile
fuselage), or if the unit is mounted not quite level.

A flashing orange light in a receiver operating in DSM2 mode indicates that receiver power was connected without
first cycling transmitter power. This "Brown-out Detection" feature warns of power interruptions. To stop the flashing,
power down both receiver and transmitter and repeat power-up. This feature is not present for DSMX.
6
Only use stabilization for the initial takeoff if you are confident that you have set the response directions correctly.

Or turn down Master Gain slightly if channel 8 is available.
