Have been working long hours at work, but tried to keep up with changes in the ArduPlane source code but it looks like nothing has change after jan 8th.
I have built two Telemetry sensor stations base on Arduino Pro Mini board that gives me one RPM, one Temp, all gps data, and voltage and current on the transmitter display.
I also added total current used (displayed in RPM 2 field on the transmitter).
