After almost 2 years of on going development since 2016, we have put variometer, energy meter (mAh, V, Curent) and just about every major telemetry parameter in one tiny package. LM0052 is the world smallest, true full-range telemetry system with build-in sensors along with diveristy receiver shrinked in the smallest possible package.
- Very high accuracy barometer built-in to the receiver to provide altitude and vario information
- True Full-range diversity telemetry provides plane information in real-time as far as you can fly your plane with any DSMX or DSM2 compatible transmitter
- Energy metering system (mAh, V, Current) are included with the provided V/I sensing unit
- 2-stage failsafe best suited for gasoline / electric application (Selectable failsafe for pre-defined position as throttle only or all channel failafe in the event of signal absence)
- Diveristy extended antenna receiver with state-of-the-art RF circuit providing umatched performance of reception
- Real time RSSI output as analog voltage / displayed on transmitter A parameter
- Glider may use the inlcuded wiring for battery voltage sensing only if energy metering system is not required for absolute weight reduction
- Optional diversity satellite maybe used to provide total of 4 receiving antennas
LM0052 telemetry range comparsion with Spektrum and Orange
The outstanding telemetry range of LM0052 are tested with Spektrum and Orange telemetry capable receiver as a basic performance benchmark. Please note that for fairness of this testing as the other receiver may not contain diveristy antenna unlike the LM0052, the setup is performed such that diveristy will have no advantage of any range improvement during this test.
Below listed telemetry reporting are available with the purchased package. No additional purchase is required.
- Included sensors / interface: Alltitude, Vario, Energy meter (Receiver voltage, Battery voltage, mAh consumed, Current), Temeprature (Internal automatically selected when the inlcuded external temperature probe is not used), RSSI out (3V to 0V) and displayed on transmitter A parameter
Telemetry receivers' feature
Comparision of Lemon Rx full-range telemetry capable diversity receiver.
- LM0051U and LM0052U will soon be available for purchase
- For (*1) V/I sensor may be required to purchase seperately on LM0051U, LM0052U and LM0041 if mAh consumed / current measurment is required

Quick start-up guide / tips
V/I sensor calibration
- V/I sensor would normally not need calibration with the LM0052 bundled unit
- V/I sensor can be calibrated following section F of LM0041 user manual
Step for setting failsafe
Fail-safe activates when the receiver no longer receivers signal (Eg. Transmitter is off / signal loss). There are 3 possible setting which are:
- No signal output to servo
- Output predefined throttle signal only
- Output predefined signal for all channels
1) Insert bind plug
2) Provide power to the unit and bind the unit but do not remove bind plug
3) Set your transmitter to the perferred position as failsafe default output and hold it to this position.
3) press the button briefly will cause the green light to be in the following status. Press the button while maintain your perferred position of the channel:
- Green LED status - none: No pulse to servo with the absence of correct reception
- Green LED status - flashing: Throttle-only preset. Throttle position had been acquired as failsafe default output
- Green LED status - solid: All-channel preset. All channels' position had been acquired as failsafe default ouptut
4) Remove bind plug
5) Turn off the transmitter now while power is still provided to receiver. You can now observe the failsafe status when no transmitter signal is present to the receiver. Please becareful that your propeller may turns if you set throttle channel above 0% in the event of signal losses. Failsafe can be useful as a last rsource to save plane for unexpected situation when the receiver is no longer receiving signal from transmitter such as interference problem.
