Yes, I've traced signal on main board with oscilloscope - I can see pulses right on the ATMega328, and if I move controls - they are changing, so it must be something with firmware. Any ideas how to fix this?

If you connected the APM and receiver up according to the Wiki then you will have routed your receiver Control channel to channel 8 on the APM. and receiver throttle/elev/aileron/rudder to channels 1-4 on the APM.

I had the same problem yesterday. Try to calibrate radio in cli-mode. It did seem to do the trick for me. I didn't have time to find out the reason for this though..

For me the fix was to upload firmware few more times - and then it worked...
