Normal Power up?

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!


 See attached video.

Thanks in advance!

  • It looks and sounds like the PWM signal from your transmitter isn't low enough. Try and move the trim on the throttle all the way down and if that doesn't do it increase the throttle travel volume (down) to 110 or 125%.

    I had the same problem at first.
