Hi All..

I am really new in this rc (so please bear with me here..).
With lots of help from friends, I manage to assemble my first quad with following spec: HK KK2 board with LCD, ESC Turnigy Plush 30A and NTM motors with Turnigy 9X Tx and 8ch Rx.

Checklist before first flight:
* Sensor test and calibrate -> ok
* Load motor layout : Quad "X" mode and check motor rotation -> ok
* Receiver test -> ok
* ESC Calibration -> beep perfectly -> (assuming) ok with stock HK firmware

Then arming the motor and put the throttle 50%.. and got the problem below..

Problem Shown:
* 3 motors spin at same speed but 1 motor (R1) spin more slower then others.
* even if we change the motor and ESC from any motors (R2, R3, R4) to port motor #1 (R1) will give the same result as above, previous R1 motor & ESC will act normally on R2, R3, R4 port.
* Factory reset and re-checked above checklist end up with the same problem.
* Try to connect the ESC directly to the throttle ch 3 in order to calibrate one-by-one but got the annoying constant beep and not responding to throttle stick.

Suspect:
* Bad firmware loaded ?
"assuming" already got the latest one with battery level on SAFE screen.
* Bad soldering ?
How do I check the solder quality on R1 or other places?

Please help me.. any suggestion will be highly appreciated..

I haven't flown her yet as i was waiting for my replacement arms. So she is newly rebuilt! Weather sucks here the past few days! windy and cold

As for the P and I settings, i have to re-tune mine because i had the 1.2 acc mod FW and it was giving me grief in AL. So i had to re-flash and reset everything.

To tune your board, turn your I gain to 0 and bump your P gain up until you see fast oscillation. once to that point, back it down until it smooths out.

Now start bringing your I gain up until you see the (slower) oscillation, then also back it down till its smooths out.

I think mine was somewhere around 45 P and 60 I gain.

Also turn your height dampening off while tuning your P and I
All of this is done with self leveling off right?

What are your P&I limits set at?

I am going to fly my KK2 board for the first time this afternoon.

Until you can get the ESC and motor to work without the KK board I would would not presume its a bad board. Maybe map one of the knobs to an aux channel to rule out the Rx unit as well?

Yes with levelling off! as for the limits i cant remember now. Concentrate on getting the gains dialled in first. The limits are more personal preference as it is a lot like expo on your radio. I think i left mine stock except for the YAW I gain. I found that is was not responsive enough for my liking, so i bumped it up to 150.

Not sure if you have watched all the videos on the first page! But pay close attention to what he says in this one

LazyZero has always kept a repository of all KK and KK2 firmware versions.
These are all available via the flashtool.

Agree with Bontide you need to make sure this is right.

Did you try the connector to the Rx up the other way, ie switch black and white/orange, constant beeps means no signal usually.

Also check the ESC's are all programmed the same with Brake off, Nimh Battery and Low cutoff etc (standard for Multirotors), you should have instructions that came with them, either using Tx and beeps or a program card.

On the KK2 the wires from Rx and to the motors should all have the black wire to the outside of the board.
