Yes, the Lemon LM0086 has indicator lights for stabilization. The green and red Status lights show whether stabilization is ON (green and red lights) or OFF (red light only).

    The Lemon stabilizer is relatively small and light. Despite its low cost, it offers long range and high performance with its “dual diversity” antenna system. A Lemon DSMP satellite receiver can be added to further enhance signal reliability but is not normally required.

    7CH Essential Instructions R1.0 2022/11/08 As delivered, the Lemon 7-channel receiver has stabilization disabled and no internal mixes set. Out of the packet it functions as a standard seven channel DSMX/DSM2™-compatible receiver. To use the receiver without stabilization, the only setup you might want to do is to change the default No-pulse failsafe to User-set, as explained in Step 3 on page 3.

    7CH Essential Instructions R1.0 2022/11/08 To activate User-set Failsafe, proceed as follows: 1. Power ON the transmitter. Set sticks and switches to the positions required on loss of signal. 2. Power ON the receiver. After 3 seconds but within 60 seconds of powering ON the receiver, press and hold the Failsafe button F.

    ON or OFF. Those familiar with the previous Lemon RX stabilized receivers will recognize that the green Stabilization Direction LEDs are equivalent to DIP switches J1, J2, and J3, while the three red Programming LEDs correspond to J4, J5 and J6.

    7CH Essential Instructions R1.0 2022/11/08 Note that when stabilization is activated, CH8, if available on the transmitter, is used for the Master Gain function. It is not accessible for other purposes. Stabilization Direction If stabilization is active, it is ESSENTIAL that control surfaces move in the correct directions to counteract disturbances;...

    Given the dual diversity antenna setup of the Lemon receiver, a satellite receiver is not normally required, but can be used if desired for extra signal reliability. It should be well separated from the main receiver.

    7CH Essential Instructions R1.0 2022/11/08 The diagram shows how the surfaces should respond with a momentary pulse when the model is moved about each axis. When the model is rolled sharply to the right, the right aileron should go down and the left aileron up, briefly, to resist the displacement.

    7CH Essential Instructions R1.0 2022/11/08 10. Adjust the stabilizer gain pots As delivered the stabilizer gains are normally at the 12 o’clock position. For first flights set the three gain pots at about the 10 o’clock position. This is a good conservative starting point that should produce noticeable stabilization.

    7CH Essential Instructions R1.0 2022/11/08 By the time you’ve finished the initial flight(s) you should have a good sense of the model’s stabilization behaviour and have achieved flyable basic settings on the receiver. 13. Fine tune stabilizer gain Optimal stabilization occurs when gain on each of the three axes is just below the level where oscillation occurs at the highest normal flying speed.

    Note that the Lemon RSSI value cannot be directly compared to other signal indicators, such as Spektrum™ or FrSky™ RSSI numbers. Lemon RSSI will read at or close to 100 with the transmitter beside the model and fall as the model moves away.

    7CH Essential Instructions R1.0 2022/11/08 For detail on all these capabilities and more, see the separate document “Telemetry with the Lemon RX 7 and 10 Channel Receivers”. Factory Reset the Receiver A reset will cancel all programming and other settings, leaving the receiver in simple, unstabilized status. The transmitter is not required for this operation.
