Lemon Rx DSMX / DSM2 Spektrum Compatible PWM 6-Channel Diversity Receiver with Failsafe

Lemon Rx DSMX / DSM2 Spektrum Compatible PWM 6-Channel Diversity Receiver with Failsafe


In Stock

Lemon RX

This is a 6 channel Lemon RX receiver which uses standard PWM servo pins. It is compatible with DSMX and also backward compatible with DSM2 transmitters. 

The Rx has diversity antennas, which can be positioned differently to help ensure a secure, and reliable connection. It's a full range receiver so range shouldn't be an issue, but in the unlikely event that you do lose signal, the Rx also supports a failsafe. Without a failsafe, if RX signal is lost the last signal command continues i.e. full throttle! With a failsafe you can configure it to default to a zero throttle, so at least your drone will crash-land rather than flying off into the distance.

The receiver weighs in at only 4.5g and it's barely bigger than a postage stamp, so you should be able to use it with even the smallest of racing drones. 

Unlike some Spektrum compatible products, Lemon Rx products aren't inferior to Spektrum products in terms of performance or reliability.


  • Spektrum DSMX full range receiver
  • Backward Compatible with DSM2
  • True diversity dual antennas with independent processor for monitoring singal on both antennas
  • Antennas extended for carbon fuselage / metalic structure installation
  • FailSafe supported for all channels
  • DSMX Satellite port

How dual antennas work

An independent processor monitors an incoming signal and choose the appropriate antenna for reception. This allows 2 different locations for installing the antennas along with different orientation. Satellite is no longer needed for receiver diversity. This greatly reduces weight with increased overall reliability in comparison to the use of a primary receiver with satellite receiver.

Binding Setup
1) Plug bind plug to the receiver.
2) Provide power to the unit (LED flashes quickly)
3) Enable bind mode in transmitter and ensure distance separation of 2 meters from receiver.
4) Solid LED light means binding is completed. Remove bind plug.

Setting Failsafe (see video)
1) Insert bind plug into the receiver.
2) Power on transmitter and receiver.
3) Set transmitter controls to the desired failsafe positions.
4) Press the side push button to memorize failsafe settings.
5) Observe that the green light at the end of the receiver turns on to indicate failsafe is set. (Repeat step 4 will cause the LED to turn off which means failsafe is disabled).
6) Remove bind plug.
7) Disconnect the power for at least 2 seconds and then reconnect the power again.
8) Test failsafe by turning off the transmitter.
