Title: KK2 tuning help!
Post by: Adityaamg on May 26, 2013, 06:10:46 PM
according to this page: http://www.badlands-rc.com/kk-v2-0-guide/
we have to set the I-gains to zero in order to set the P-gains.
and how do i set yaw?? 8-)
still not sure about it, please help! :help:





currently my quad is flying okay, but nit stable enough for fpv. :headscratch:

First start tuning with P and then move on D and then finally for I

Haha, ya
proportional integral only.

Sorry - I don't know about KK2 but in general PID tuning takes place in the before mentioned steps...

yeah, but my question is, should i turn I-gain to Zero when tuning P-gain or not?

For tuning first you have to find optimum P gain and for that it is good to bring I gain to zero so that it can not interfere with P gain. Once you find the P gain you can find I gain. Less I gain will bring copter to the level automatically. If you increase I gain you will get your copter in heading hold position, which is good for learning. Keep the I gain same as P gain or 50% of P gain.

so while tuning I-gain, do i have to bring down P? so that it doesn't interfere with I????

can i fly with I-gain turned down to zero? and tune it that way rather than tying it down with strings

Once you find P gain you don't need to change it, just keep it as it is and find I gain.

Try flashing it with v1.5 or the newer v1.6. My quad flew good with the stock v1.5 settings. EDIT - In the RECEIVER TEST option, trim all the values to Zero before you fly.

Aditya, it would be wise to define your problem so that you can get some timely help.

my quad is flying, but not so great.

 i have issues upgrading the firmware from 1.5 to 1.6.
how do i set my yaw PI settings?
my quad is going forward and yawing on it own

1.What kind of 'issues' are you facing with flashing your KK2?
2.Have you trimmed all the 4 controls to zero in the RECEIVER TEST menu?
3.A video of your quad in action would probably help understand the actual problem...

Post photos and flight videos me your quad. Would like to have a look at it..

aditya-

"And I can confirm that the ESCs and servos, even those connected to M2-M8, (cause they load the outputs of the KK2) must be removed when using a programmer that supplies power to the KK2! Else it is a chance of bricking the KK2 due to low voltage during flashing."

Got it veloci bhaiya, even though I sold my kk2. :(

frame is flexing.. i am making another frame

Its a good thing to do but, the flex is NOT the reason for the uncontrolled yaw that you experience in your quad.
