 :hi:

Installed the KK2 board and everything seems to be fine, however I have a lazy motor and that makes the quad spin. New motor has been ordered and should be here anytime. I also had the same problem with this same motor using the KK4.7, do you think it's because this motor's ESC is the one that provides power to the board?(this is the only motor's ESC that has the red wire connected, the other ESC had their red wire cut)  :132:
Thanks

According to the manual, cutting the wires on the other esc's is not necessary, as only the motor 1 connection powers the board.  I haven't cut any of my wire and have no problem.

I'm gonna try joining the cut wires together and see the results. I'll keep you posted  :130:

 :hi:

Got the wires back together but the problem is still there. I'll only find out what the problem is when I get the new motor, propeller and ESC, that way I can determine the faulty component, but I believe the problem is the motor. Now I have to wait for it :212: :215:

I am sure it's the ESC.
What is your ESC setting? such as, battery type, start mode and timing.
If you have the USBASP wire, you might try flash the ESC with SimonK fw.

Glad you mentioned flashing the esc.  Have you ever done that?  I've been reading the pros and cons, and I'm not sure I want to do it.  I think I have what is needed to do it, just not sure if it is worth doing.  What do you think?

 :hi: guys

I changed the motor and apparently everything is working, but it is still spinning slowly clockwise, do you know how to solve this? Also, how can I make it less agile and more stable?
Thanks

Just use the trim on your Tx for the spin, to make it less agile and more stable I guess you can use =>

"Stick Scaling"
Here you can adjust the response from the stick to your liking. Higher number gives higher response.
Similar to the endpoint or volume adjustment on your transmitter. You can also adjust your
transmitter to adjust the stick response and use the stick scaling if you want even more response.

Thanks Mav, I'll try the stick scaling and some dual rates to tame it down. Do you think I could use subtrim to stop the spinning?  :132:

No, I haven't done the fw upgrade. I am afraid to fail. Because some people flash 4 ESC, and one of them doesn't work.
But I am tempted to do it. Maybe one day when I can't solve this wobble problem.

What's on your receiver test screen? If you don't get 0 number, use sub-trim to zeroed it. But before you do that, make sure your trim is zero. Hopefully it will solve your drift. What is your rudder P and I gain?
Use stick scaling to make it less agile. Agile also can cause by to low I gain. What is your aileron P and I gain?

 :hi: Pinguin

I got all the numbers to be at zero and drift is better now(going to add some more to stop the drift. I use the default settings for the gain:

Roll/Pitch P-gain: 30 (For a small 25cm size set to 20)
Roll/Pitch P-limit: 100
Roll/Pitch I-gain: 0
Roll/Pitch I-limit: 20
Yaw P-gain: 50
Yaw P-limit: 20
Yaw I-gain: 0
Yaw I-limit: 10
I'm gonna try the stick scaling to tame it down  :130:

What I experience, with zero I gain, the multi is so wild. Increase your I gain. Start with 10.
Don't change the stick scaling yet.

I'll try that tomorrow and I'll let you know how it goes. Thanks :130:

Papa, how about a little video to let us see what you are experiencing?

I wish I could upload a video, but today as I was testing it I crashed and now one propeller is broken. I do have spares but they won't fit, so I'll have to drill it to fit the prop adapter. I'll see if I can get the job done by today and video as well
