Hi,

I have built a x525 hobby king quadcopter and this is my first quadcopter. My transmitter is not getting armed with kk2.1 flight controller. I have checked "Receiver Test" menu in kk2.1 flight controller. It shows all the signals fine. I calibrated each ESC individually in throttle channel. All motors are spinning fine if I calibrate them individually.

But once I plugged all the ESCs in kk2.1 flight controller. None of the motors spins. I tried to calibrating all ESCs in a single shot (refered ).

If follow the above procedure I found that FSCT6B is not getting armed with kk2.1 flight controller.

Please help, I am trying it for last five days not able to find any solution.

Thanks & Regards,
Surojit

@surojit_salt,
Did you do ACC calibration?.
You'll find it some way down the menu list. Just press Enter and follow the instructions.
I think the KK will not arm till this is done. (Has to be done only during initial setup, or after factory reset)

@k k Iyer
I did acc calibration after factory reset. I have done all those procedure mentioned in youtube atleast for 10 times. Not able to understand why it is not working?

also if your CT6B is new then go through given link and Calibrate your radio using this software.

Option 1) Factory reset your kk2.1 i had the same problem after resetting the control board it was all fine.
Option 2) Make sure you switch on your transmitter first and then your quad.

Remove dual rate settings on Tx.
Set EPA to 100% on Tx.
Check rudder movement on KK display.
Will not arm if rudder throw inadequate.

Also check mode shows Aux or Stick as desired.

Dont worry. It will work!

Edit: Also check if rudder channel needs to be reversed!

Haha.
I may be old, but i'm a real newbie!
Learn a LOT of stuff in the last three days of experimenting.
Now able to hover indoors for 5 minutes at a stretch, between 12" and 24" height, over a 10'x6' carpet!

@satyagupta of quadkopters
Thanks for the ST360 for 5500

@vishalrao of kinetic hobbies
Thanks for the Haiyin 3s that you sent me free. Its getting 5-6 cycles daily now with my quad experiments

I see one new member asking for cheapest, cheapest, cheapest.
I wish he would realise that there are GOOD HONEST sites right here in India...

@K K Iyer

Thanks for the manuals and suggestion, But unfortunately I have not able to spin my motors. My transmitter's current setting screen shot is attached with the mail.

Here are few questions
1. It would be great if you can point out the section I should refer to resolve this issue.
2. How to find out whether rudder throw is inadequate for my transmitter.

Eagerly waiting for your response.

What is the method that you are following to arm your quad ??

first, check each channel direction is correct - through receiver test menu . reverse channels as required.
then see whether max. and min. endpoints for aileron, elevator and rudder channels are 90 to 100 and -100 to -90 respectively (this can also be checked from receiver test menu) - if it is not, you have to adjust endpoints of each channel on transmitter configuration .

Read "Reply #3" Again, will solve 99% problems in CT6B

I  used above url for arming transmitter.

@akhilzid
I tried to install the software you mentioned. But it is not working in my machine. I am having Windows7 home Basic 64bit OS.

@akhilzid
I have attached the screen shot whenever I am trying to open the T6Configuration App.

The following prerequisites are required:
Windows Installer 4.5
.NET Framework 3.5 SP1

@akhilzid

I able to open the T6Config software only after installing MSChart.exe. How to setup my transmitter? Do you have any manual?

I have not able to spin my motors.

Let us proceed logically step by step.
Before you can spin the motors,
The first step is: is the kk2.1 lighting up and going to 'SAFE' screen?
If not, this has to be tackled first.
If yes, next step is: is it getting armed?
If not, check that display shows 'right' rudder when you move the rudder stick to the right.
Otherwise reverse rudder on Tx.
Also in your LOW rate on dual rate, change it from 50% to 100%.

Let me know when you reach this stage. Then we will calibrate the ESCs.
Sorry for delay. Got a call from Sooraj. His quad fly away, but was later found!

nothing complicated

just select comport
click connect
click calibrate
move all sticks to their max and min position
click ok on the popup box
done

@akhilzid
here is the screen 1

@ K K Iyer
I have performed the steps you mentioned. Now What should I do???

@surojit_salt
Is it getting armed now or not?

Armed mean if I move Rudder on right then in kk 2.1 flight controller LCD display should show "ARMED" in screen? Right. This is not happening.

Yes, screen should show ARMED after moving rudder stick to bottom right.
If it doesn't work, try bottom left (incase rudder needs to be reversed)

But first are you getting the SAFE screen?
