- World smallest: Fully enclosed VTX + CMOS + OSD + 5.8GHz tranmission

- VTX with extremely high quality and sensitivity CMOS for ultimate realistics real-time video transmission. 712*562 pixels with 16V/Lux*sec.

- 25mW class video with extremely light weight antenna with very good matched design to minimize reflection and RF energy losses. Range is comparable to other branded 25mW VTX that uses the very heavy cloverleaf antenna.

- OSD (On Screen Display) that let you know the current settings with real text displayed. Knowing the manufacturer compatability and actual transmission frequency without guessing with the back LED display.
 
- Remote shut down. Save power for small plane during launches and activate VTX only when the plane is high up in the sky.
 
- Able to change manufactuer compatability and frequency with either pushbutton or servo signal (by toggling switch a few times on transmitter).
 
- 2 sets of cable: single cell LiPo opertional. For 4.8V to 7.2V 2nd set of cable is provided for direct connection to standard receiver header pins.
 
- Designed to best suited for hobby modification with standard connectors and antenna connectors
 
- Polycarbonate casing that can withstand very hard mechnical impact
 
- With Standard 65 degree lens
 
"After more than a year of R&D with many engineering challenges, we are able to do extreme miniaturization at an affordable price for the hobby market. A 0.05mm offset of imprecision during production stage will be catastrophic with very low yield rate. This is a project that we almost canceled. I am sure that this unit will set a new milestone for the RC industry of what a truly refined design and precision engineering are. If hobbyists are interested in supporting truly refined design at slightly higher cost, we will have a lot more exciting products coming in the following years." --Lemon Rx Engineering Team

User Manual re-direct link 
- To be organized. Please see below for website version of user manual

1- Cable set
   - 2.54mm spacing wiring set is for voltage between 4.8 to 7.2V
   - 1 wiring set for use with 1S battery such as Horizon Hobby’s E-flite 1S battery
2 - Compatability chart
   - See above
3 - Turns off VTX remotely
   - A servo pulse of 1ms, or -100% (for Spektrum transmitter) will effectively turns off both RF transmission and CMOS camera
4 - Display current settings
   -  Repower the unit or push the button briefly to display current settings
5 - Change manufacturer compatibility
   5.1 - Method 1 - via push button
         - When OLED display is off, hold the button until it displays current settings.
         - Before the display turns off, press briefly to change the “manufacturer” for compatibility.
   5.2 - Method 2 - via receiver
         - Make sure the VTX is connected to a receiver with supplied wiring set while also powered by the receiver. (eg. Connect VTX to Rx’s AUX1).
         -  When OLED display is off, toggle 0% to 100% as fast as you can (at least 8 time within 1.5 seconds) will trigger OLED to show the manufacturer is changed.
6 - Change channel / frequency
   6.1 - Method 1 - via push button
         - When OLED display is off, press the button briefly to displays current settings.
         - Before the display turns off, press briefly to the channel / frequency.
   6.2 - Method 2 - via receiver
         - Make sure the VTX is connected to a receiver with supplied wiring set while also powered by the receiver. (eg. Connect VTX to Rx’s AUX1).
         - When OLED display is off, toggle 0% to -100% as fast as you can (at least 8 time within 1.5 seconds) will trigger OLED to show the channel / frequency is changed.
