I am trying to find out what is (normal) at power up.
I have purchased a 3DR Hexa kit with 850Kv motors and the 20Amp ESC's.
Upon powering up I get an escalating tone then 3 beeps then it sounds like 3 or 4 more beeps
but alot faster.
I can not get the ESC's/Motors to arm.
What am I missing? HELP!
Thanks in advance!
