There are Ultimate LRS users accross the globe and I’m very happy to receive their kind messages. This page is dedicated to the creativity of ULRS users and I’ll post their videos and other projects such as 3D printed cases, antennas, trackers etc. Thanks to all of you, and I’m preparing bumper stickers and goodies for you 🙂
- 1 User videos
- 2 Antennas
- 3 3D printed
- 4 Other projects
Notice that the telemetry is always turned on with ULRS, the ranges obtained in the example videos below are thus with telemetry enabled.

Moxon antenna for Ultimate LRS
Rcgroups user Beemond made a very nice Moxon antenna, check this post for the full description.

Home made RC transmitter
It use an Atmega micro controller and read 6 ADC that connect to potentiometers for channels of 1,2,3,4,6,7 and ch8 use simple switch for digital input.
For mode selecting at channel 5, I prefer to use 6 Momentary switches for different modes, so when press any of 6 switches new mode is selectable, of course in my previous version, I used 2 switches (2 and 3 state) for 6 modes.
This program get 3 times sample for each potentiometer, then use average value and for digital input simple reading pin is used, then sends all values as ppm signal to specified ppm output at timer interrupt, each 20 ms.
It also uses one of ADC channel for reading battery voltage and 3 levels are defined for different blinking the battery Alarm Led.
Because different models of potentiometer have a little different behavior, it needs at first to calibrate each potentiometer that give the best range in 1000 to 2000.
In this version the “exp” or “end point” for sticks is not defined and I think that for Arducopter it’s no needed.
I used this program about 2 years with your ULRS versions 1.06 and 2.xx and hadn’t any problem .
Integrating an APM inside the OrangeRX case
User WinerS did something apparently impossible, integrating an APM board inside an OrangeRX case !
