OpenLRS is an Opensource RC and i'm the developer of that system.
Stop the video on 1:08 and check the receiver.
And check the pinout or something. http://www.flytron.com/openlrs/146-openlrs-receiver-v2.html
Only the difference is 6 pin ICSP. We don't need that because of our production procedure.
Now the question is "What can i do?"
If i cant find an answer about that, i will stop to designing open source hardware.
