Help!
KK Board won't arm - Tried everything!

I have a huge problem. I got this board here for my first Quadcopter:

http://www.ebay.com/itm/KK-V5-5-Mult...item256fb9c4bb

I loaded the 2.0 firmware from the KK site onto it. No problems there.

I am using 30A Dentrum ESC's and the FrSky D4FR RX (http://www.frsky-rc.com/ShowProducts.asp?id=89) using the PPM output on CH2 (all channels CH1-8). I connected the RX to the Elevator Channel on the KK board. It seems to work. I am using the Turnigy 9X with er9x firmware.

My channel setup is:

CH1 = Ailerons
CH2 = Elevator
CH3 = Throttle
CH4 = Rudder

So far I did:

1) Calibrated each ESC and also tested each motor. All works fine.
2) Turn on TX and Throttle to 100%
3) Turning YAW to zero on KK board.
4) Turn on KK board - LED blinks once and turns off.
5) Motor starts with typical 2 beeps and go to a constant 1s beep after that.
6) Now KK board flashes very fast about 2-3 times every 1-2s.
7) Push Rudder to 100% right while holding throttle at 100%
8) I wait a few seconds and the ESC beep 2 times
9) Throttle to 0% while holding the rudder still 100% to the right
10) The ESC's now respond with a kind of melody-type tone (de-da-du) after a few sec and than start beeping every 1s again.
11) I turn off the board
12) Turn it back on with Throttle to 0% and YAW on center.
13) The first time after I do this, the LED is on the whole time and the ESCs start to beep erratic like an alarm tone.

Whatever I do, I don't get the board to arm. It tried with +/- 125% on Throttle/Rudder and every combination that is possible. I also tried a 2.5 Firmware from another site. Btw I am using the X-Copter firmware.

I will upload a video shortly!

Once you program the esc's you need to unplug the power from the board then return the yaw pot to 50%.I have read there is no need for endpoint adjustment.
You should only get the normal first beeps then a short pause.the next beep you return the throttle to 0.
The reason you are getting rapid beeps is the throttle range isn't set or incorrect.

On some boards the yaw pot is backwards. You might try turning it the other way. To check, plug in the board with your tx on and throttle to zero. Turn the yaw pot one way and if you get a solid light, that will tell you where "zero" is on the pot. If it doesn't light up, turn it the other way. Also, your throttle end points on your transmitter should be 100%. 125% is too much.

Ok I just tried in the other direction and yeah the light stays solid but when I try to calibrate the board, I only get the erratic tones from the ESC. If I turn it the other way I get the 2-3 flashes per second from the LED...

Do I need reflash or is the board damaged? Or what else can I do? Extremely frustrated - trying now for 3 days.

Are you using the Lazy Zero Flashtool? That's the one that's always worked for me. When you got the solid light, did you try doing the esc calibration? If all else fails, you can do one esc at a time hooked directly into your receiver. I've done it both ways. Either one works.

Yep that's what I am using. I calibrated again the ESC's individually - no luck.

What firmware should I use?

In the end your esc's sound is do-re-mi indicating that esc's are in programming mode.

And set your throttle in mix screen to 100% not 125%.

You're using what X-copter firmware from who? You have from Kapteinkuk (v4.7x), Minsoo Kim (XXcontroller KR), Mike Burtons (XXcontroller from Mike Burton) and you have Nexcopter from happysundays.

9) Throttle to 0% while holding the rudder still 100% to the right - this is not right

You may need to reverse your throttle channel. It doesn't sound like you ever really completed throttle calibration.

The "alarm tone" from your ESC means your throttle is out of range from what it is expecting. This means you've never completed throttle calibration.

Lower your throttle trim on the Tx as low as it will go. Then try arming the board. If nothing happens, try reversing the throttle in your Tx and try again. Be sure not to have any props mounted when you try this.

I fly CC and am not too familiar with KK. Does the blue light mean the board has armed? If so, that's a step in the right direction.

Next, check your throttle subtrim and make sure it's set to zero. In fact, it's probably good to make sure all of the subtrims are set to zero unless you know of some KK reason why they shouldn't be.
