I have spent 3 hours trying to get the new IRIS to arm... without luck. The sequence is simple and all appears to be fine until the arm with the rudder right, which just does not work. Here is what I do:
TX on (switched in stabilise mode), plug in battery, tune plays, press top button, goes solid red+tune, (wait for fix) green flashing LED. Hold throttle bottom right (for 30sec) nothing, no arming no throttle ...
In mission planner (USB connection) the virtual horizon shows correctly, but the radio calibration shows no green bars at all. Terminal -> radio shows zero for all channels. It looks to me like the receiver isn't working or is not bound. No instructions mention binding RX, and I don't want to start dismantling the case it in case it is something serious that needs replacing.
What do you suggest? I have had no problems with many APM2.6 in fixed wing and quads, but havn't had a PX4 before. Is there something obvious I have missed?. I cant find anything on the forums and I thought the IRIS was supposed to be ready to go out of the box.
