14. Restrict Master Gain (if applicable) 

Master Gain is very useful to allow for 

varying wind conditions. But you don’t want to accidentally set it to 

very 

high gain, which can cause disconcerting oscillation. Hence, once 

you’ve set up the receiver pots with the Master 

Gain knob or slider about the middle, you may want to limit the maximum available Master Gain. 

The simplest way is to use Travel on the Servo Setup menu to limit the throw on channel 8 (Aux3) to, say, 20% 
on the high side, (numbers -100, 20). 

Another way is to use Channel Assign to change channel 8 (Aux3) to control by a switch, then use Digital Switch 
Setup to set it to, say, -20%/0%/10%. Adjust the values as required to give a suitable choice of three settings. 
Note that those particular settings are good for flight but 

don’t allow Master Gain to be used to effectively shut 

down stabilization and thus should probably not be used together with Always-ON. 

Using Telemetry 

Telemetry is independent of stabilization and can be used with the receiver in stabilized or unstabilized 
configuration. 

A separate document 

Telemetry with the Lemon Rx 7- and 10-

Channel Receivers” 

[LINK] 

explains in detail how 

to setup and calibrate the Telemetry function. This section just mentions some highlights.

 

The Lemon Telemetry Receiver sends data on receiver voltage, temperature and RSSI (signal strength)

8

, plus 

altitude and vertical speed (vario) information from a built-in barometric sensor. Flight battery data can be 
provided by a voltage sensing wire or the optional V/I (voltage and current) sensor; the latter enables the 
transmitter to calculate battery capacity-used (mAh). Lemon telemetry is displayed using the existing display 

screens and, where available, the transmitter’s voice capability.

 

The transmitter can set alarms, in some cases just tones but often voice 
announcements. For example, an alarm tone and warning can sound when 
the flight pack voltage drops to a preset value or if the models exceeds a 
certain height above ground. 

To utilize this capability on a telemetry-enabled Spektrum

 transmitter, turn 

on the radio and power ON the receiver. Go to Telemetry. You will see a display of parameters potentially 
available from the installed sensors. 

Run “Auto

-

Config” if they do not appear.

 

The Settings item allows selection of either metric or US units.  

To determine how the various parameters are used by the transmitter, go to 
any one of the items and double click. You will then see a screen offering 
several options, which vary from one item to another. Typically, the choices 
allow maximum and minimum values to be set for purposes of triggering 
alarms and voice reports to be made at regular intervals or when a switch is 
flipped. Note that not all of the parameters displayed on the Telemetry screen will turn out on inspection to be 
functional and useful.

Note that the Lemon RSSI value cannot be directly compared to other signal indicators, such as Spektrum™ fades or an 

FrSky™ RSSI number. Lemon RSSI will read close to 100 with the transmitter beside the model and fall as the model 

moves 

away. Even at the minimum reading approaching 20, the signal should be adequate for control.
