This is an 8 channel PPM receiver designed primarily for quadcopters Spektrum users. Lots of flight controllers are compatible with PWM, PPM and SBus, but not with DSMX or DSM2, which is the modulation used by Spektrum radios. This Lemon RX receiver uses PPM and is compatible with DSMX transmitters. PPM makes for a really tidy install as it only requires one input for all of the channels, instead of a wire for each channel like PWM does. If you are using a Naze flight controller, by using PPM it leaves most of the input channels free, these can then be reassigned to other things like GPS, OSD and telemetry.

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 2.7g and it's about the same size as a postage stamp, so it is suitable for the smallest racing drones.

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

Setup Instruction
It is highly recommend to enable FailSafe as some quadcopter flight controllers do not have a fail-safe system implemented. If the quad copter is too far from the transmitter and the RF signal fades or is lost the failSafe allows the receiver to output a default signal when the signal is lost to keep the quad copter flying until the signal is recovered again.

Binding Setup
* Plug bind plug to the receiver.
* Provide power to the unit.
* Enable bind mode in transmitter and ensure distance separation of 2 meters from receiver.
* Upon successful binding and if FailSafe do not wish to be set, remove bind plug upon binding.

Setting Failsafe
* Start by binding the receiver to the transmitter in the normal way.
* Proceed as follows to set failsafe (see video: https://www.youtube.com/watch?v=FyW1v12dv_k)
* Ensure that transmitter and receiver are turned on.
* Insert bind plug into the receiver (Note: to set failsafe, bind plug is applied only when the receiver is turned on).
* Set transmitter controls to the desired failsafe positions.
* Press the side pushbutton to memorize failsafe settings.
* 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).
* Remove bind plug.
* Disconnect the power for at least 2 seconds and then reconnect the power again.
* Test failsafe by turning off the transmitter.

Pulse Sequence
* The PPM pulse sequence is in the following order:
* Throttle Aileron Elevator Rudder Gear Aux1 Aux2 Aux3
