A quick overview of the setting in side the KK2 multicopter controller board.

Hi there,
could you tell me please what does P and I stands for?
Maybe then I can figure out my the best settings for my quadcopter.
Thanx mate. Log In to reply

I don't exactly know what the letters P and I stand for but, I do know what they do. The P gain is how sensitive the gyros will be and how much movement they will correct for. The I gain is the same only with the Accelerometers. The limits are how much the gains will compensate for the movements they detect. Leave the limits as default (100 P limit, 20 I limit) and increase the gains, one at a time until you see occupations, and then back the gains down a little, and it will be as stable as it possibly can be. I hope that helps! Log In to reply

Thanx mate, that helped.
I found out yesterday that if I trim my quad in self-leveling mode so it flys to my satisfaction, and turn off self-leveling it flys like a dream. I switched it off by acident and was surprised how well it performed, even in strong and gusty winds.
Originally I am a heli guy of all sizes and noe my quad flies like a heli with a V-Bar stabilizing system.
I love the KK2 board. Its just a fantastic piece of work of Rolf Bakke. Log In to reply

Proportional Integral Derivative.
P = something like pitch/roll gain
I = something like gain for correcting for wind.
D = attempt to dampen oscillations by predicting what it will need to do.
I notice you do not mention the need to solder a connection to the board for reading voltage output...
Kapteinkuk himself said in his KK2 Q&A http://www.rcgroups.com/forums/showthread.php?t=1675613 that it is necessary to connect to an un-populated hole in the PCB to monitor battery voltage. Also, Youtube user ( dhdsracer ) made a video how-to on soldering to that hole.
Yes, I did have to solder the connector onto the board, I can't believe I forgot to mention that. Dhdsracer's video is a very good reference and that is what I used to setup my board for voltage check. Thank you for pointing this out :) Log In to reply

At least - that's how I understand PID.

Did you have to do this?
