hello everybody
I just received a Rctimer 433 mHz kit mounted on an APM 2.
The modules are communicating, the led is 
solid green, I can load the settings but when I want to connect in flight data mode, it does not work, I have an error message (time out)The com port (17) is the right com port, it's not the usb (unplugged). I tried to move the com port to 5, to change the com port speed to 57600.....
And the firmware are not the same: 1.7 local and 1.6 remote ......
Any suggestion?

Connect the remote air radio to usb via FTDI and update the firmware.
