  • the beeping would indicate that possibly there a problem with the connection to rx unit and the apm or esc cables to apm.

  • Well i am no expert by any means on this but i had a lot of problems similar to this with my first quad, double check the connections then with no props on the quad try the throttle up to full throttle see if they arm that way try one unit plugged directly into the APM by it's self to see if something is taking all the ESC's down hope this helps.
