Description 

The Lemon LM0087 10 channel Stabilized Receiver is intended 

as a “

universal

” integrated full range 

DSMX/DSM2

-compatible receiver. It combines full-range telemetry functions

1

 with the well proven Lemon 

stabilizer technology to provide AS3X®-type stabilization.  

The slim line case, 10 channels and built-in barometric sensor will be particularly attractive to glider pilots 
requiring complex wing surface functionality in a compact package. Rate Stabilization 

(“smooth out the bumps”)

 

is optional and if activated can be switched on and off in the air; it is likely to be attractive to most users.  

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.  

The unit works with virtually any Spektrum or compatible transmitter with five channels or more

2

, including the 

first- and second-generation DX series, as well as the newer NX and iX transmitters. The receiver automatically 
switches mode between DSMX

 and DSM2

 as required. 

An eight or more-channel transmitter with voice capability allows use of all the available functionality, but 
configuration options allow operation with radios having fewer features or channels. The Lemon 10 channel 
receiver also works with open-source transmitters such as Taranis and Turnigy 9XR using an add-on DSM2 or 
DSMX compatible module, as well as with Multiprotocol transmitters such as Jumper and RadioMaster.  

Lower cost versions of the receiver with no stabilization function, or only 7 control channels, are also available. 

 

Connections 

The receiver has six sets of pins on each end of the case: on one end, channels 1-5 plus an optional isolated BEC 
(separate power source) input, and on the other, channels 6-10 plus another isolated BEC input. The channel 10 
pins can also function as a normal bind plug connector. In addition, there are connectors for an optional satellite 
receiver and an optional voltage/current sensor or simple voltage probe for telemetry. Note that channel 1 and 

 

1

 Essentially the same as those of the earlier Lemon LM0052, 7 channel receiver. 

2

 Exceptions include the original DX6 Parkflier transmitter and the Orange T-Six DSM2.
