any member please help me ,  HK Quadrotor control board is allredy programed (redy to use) or requed programming before use. i held two hk quad board both is same problam, gyro is not working on tilt and ailron, elevetor ,rudder not working but throtle is working
 i want some help please help any member via pm or my no.09982162538

Hey bro hk board comes with + configuration preinstalled.

Check if you have set the gyro gains properly.
Have you followed proper instructions for setting it up? if not then follow this link http://www.kkmulticopter.kr/index.html?modea=manual

hello Sir..
i hve the same problem......i hve a new hobbyking multirotor controller board and only throttle is working...
do u find any solution...pls reply me as soon as possible....i will be thankful to you.

First check your connection. Refer manual for correct connections and procedure. Put all gyro pots at around 50% and then arm your board.

sir do u think that this is due to not properly arming the board??

are u able to arm the board?
ie by taking stick to lower left?

some time it get in programing mode which just turn motors.... i guss is the prob.

u following manual mentioned in above post?

I am not saying that. Most of the problem arise because we don't follow proper procedure. So I just want to say recheck if everything is correct and proper and then try to identify what/where is the problem.

Also try to be be precise about your problem. Identifying only throttle working cannot lead to possible solution. So if possible post what procedure did you follow, position of gyro gain pots, behaviour of gyro etc.

I too am using the HK 2.1 control board right out of the box in a + configuration quad. While setting it up using the manual, I see that I have to reverse a couple ( rudder and ailerons) of Transmitter channels.

Am using the HK/Flysky transmitter and receiver. But dont have the programming cable. Is there any alternative way to reverse the channels?

Or any source besides HK (backorder right now) that one knows of where the cable is available?

Thank you.

I guess you are talking about hk/flysky 6ch radio. You will need programming cable to reverse the channels
Checkout following link I think it is available

hi friends,

i am facing problem with my tricopter.

when i connect battery red light on HK bord blink for a fraction of second and then goes off.
All ESC beep like they are in programming mode.

none of my radio inputs work.

Can any one help on this?

if i connect each ESC individual (without HK bord)then it works fine.

If you have build tricopter then can you please upload image of wiring.

thank you,
Atul

my problam is solved , check your radio throttle on minium and then move throttle stic  left or right for few second and check your board led is turn on and then redy your quad rotor for flying (my english is weak for more help please call me 09982162538)  :bow:

Thank you Spitfire.

For future reference, could you post the names of all the online or offline RC shops in India you know of?

It is already listed

hi friends,

i am facing problem with my tricopter.

HK bord is flashed properly for tricopter 2.5 firmware.

All ESC are programed with programing card.

if i connect each ESC as individual (without HK bord) then it works fine.

When i connect battery (with HK bord in place) red light on HK bord blink for a fraction of second and then goes off.

All ESC beep like they are in programming mode.

None of my radio inputs works.

Can any one help on this?

If you have build tricopter then can you please upload image of wiring and connection.

I doubt that i might have mess up with wiring

thank you,
Atul

Moderator Note: Merging your question in this thread for better visibility. Lets keep all HK board related questions in this thread.

What radio are you using? You might have to reverse the throttle channel.

See the image below for wiring.

(http://www.kkmulticopter.kr/multicopter/images/black_tri.jpg)

Make sure all the connection are correct. Ground wire should go to ground and singnal wire should go to signal.
Then put all gyro gain pots at 50%. Lower your transmitter trim. and then connect your battery. Red light will blink for once. Now if ESC are still making noise then lower trim further untill sound stops. Now use your rudder stick to arm the board.

SLS : I am using Hitec Optic 6 sports radio.

Thank you spitfire !

ok, let me confirm my understanding and then ask the query.

So, my current wiring is something like the attached image.

as per your diagram:

Motor 1 should be connect to board where M1 is written.

Motor 2 should be connect to board where M2 is written.

Motor 3 should be connect to board where M3 is written.

Yaw servo should be connected to board where M4 is written.

And seems like i have done everything properly till this point.


Now I should:
A) Set all gyro gains to +50% and
B) Lower my transmitter trim.


A) is pretty clear to me but not sure about B)

Can you please explain which trim you are saying ?

I am using Hitec Optic 6 sports redo. There are 4 trim buttons (throttle, rudder, aileron and elevator )

which one should i lower or all of them?

also, one basic question i have is why the ESC's are beeping?  and how the A & B will help?

Thank you,
Atul

Opps my bad :banghead:  That should be Throttle trim. Lower your throttle trim. Keep all other trims to neutral.

ESCs are beeping because they are not detecting min throttle signal. We lower the trim so that ESC can detect min throttle signal and stop beeping. Zero value of any pot leads you to change settings of the board like gyro reversing. So if you want to arm board them make sure no pot is at zero.

Read link below for more details. If you follow ESC calibration procedure as mentioned in link then you dont need to lower throttle trim. But in most of cases lowering trim does the job without calibrating ESCs on board as mentioned in the link. Ideally one should follow the procedure mentioned in manual.

Thank you again spitfire !

I will try it tonight and let you know.

Lowering trim did not helped.  when i tried to trim it show me 0% till -50% but still did not start motors.

I tried the ESC calibration as follows:
 

turn on the transmitter
set the throttle full
set yaw gain pot to zero
plug in battery to ESC's
Red LED flicker on board
beep sound from ESC
Red LED flicker on board
beep sound from ESC
I set throttle  to zero
i get
beep .... beep,beep
beep .... beep,beep
beep .... beep,beep
N times

not sure if its done so tested it with yaw pot set to 50% and it did not worked..

i tried it many times but no luck.

one time after setting throttle 0 i tried to increase it and motors started sniping.

but then next time same beep beep from ESC

do you know what i m doing wrong?

thank you,

sorry for the background noise video quality ..but hopefully this will give you better idea of my problem.

Ok, so finally i found the problem.... i did not ARM the board

just in case you dont know (like me ) Arming board is procedure that you do by holding rudder left/right on start up.

I think this activate the board.

now the only problem i have is Ruder control does not work.

any help on that?

Thank you,
Atul

What exactly do you mean by rudder control does not work? Are you able to arm the board?

yes, board arm properly.

when i open throttle it response properly

if i tilt my board i can see the motor speed is changing

but then problem is when i move the ruder control on my TX tail servo does not respond.

any help on this?

Thank you,
Atul

Put your throttle around 30-40% and then check rudder response. When throttle is at zero, servo does not move.

oh ok, thank you spitfire.

I will try it tonight and let you know.

Regards,
Atul

one question though... why?

I mean why Yaw servo does not work at 0 throttle as normal plane servos work, right?

beacuse it is such programed in tricopter kk frimware...

more the throttle more sensitive the servo responds to yaw...
which is must....

so at 0 throtle it is 0 sensitive....

oh ok, make sense...

thank you Karan

spitfire you Rock!

When i open throttle around 30-40% rudder started to work.

Thank you,
Atul

ok, now next problem. :)

Motor 1 seems to run slow.

when i try to give 40-50% throttle M2 & M3 goes up but M1 sill touching to ground.

M1 is spinning opposite to M2 & M3 as per attached diagram.

My question is do i need to put M1 prop inverse of M2 & M3?

or do i need to adjust trim ?

Thank you,
Atul
    

motor M1 and M2 must rotate opposite...
direction of rotation of M3 is your choice...


and yes... you will need "counter-rotate  prop" (or tracker-pusher in other lang)... inverting prop wont help... it is same on both side... 

u can try it b4 posting...

and one more thing...

as tri has servo to stabilize yaw...
it can fly with all prop rotating in same direction...

but a servo will tilt more to stabilize yaw... so a quite large component of thrust from tail motor will go in balancing yaw...

u can tilt front motor to certain angle... to minimize load on tail motor...  but then also u need to compromise with power, stability, and tri may hover few degree tilted.


i tried in my tri, it didnt workd so well

I use all props in same direction.
If one motor is running slow then just try to increase response by adjusting trim.
You will have to use trim so that when tri leaves ground it is leveled.

got it, thank you.

one more question.

For testing I removed all props and hold tri up in air.

Now if I tilt it on right then  then right motor speed up for few seconds and then all motors come to same speed even if tri is in tilted position.

My question is: is it right behavior ?

I was expecting that KK board should have keep the right motor in fast speed compare to other motors till the point i bring it to level position.

I can think of 2 reasons why it only speed up right motors only for few seconds when tilted right:

1)   Its coded that way
2)   Gyro forget the initial value and consider new tilted angle as 0 after some time

I don’t think gyro will forget initial value and not sure why they might have coded firmware such that it will only speed up one motor for few seconds only?

Thoughts?


Regards,
Atul

Yes. This behavior is right. Gyro do not remember initial value of angle. it just measures change in angle and not the value of angle. For measuring value of angle you need accelerometer and magnetometer.

i was at trimming stage and battery went off.. so i change the battery and now my board do not arm...

i tried
1) throttle trim ..
2) ESC calibration by setting yaw gain 0

any idea why my board do not arm?

thank you,
Atul
