I've been waiting for AGES, finally got all the parts and got it flying. Just trying to dial in the PID settings, very confused though about what each of them do exactly. Ive got it up by adjusting the P in Acro-mode. Can you guys let me know what they do. :) Also i saw something about "Gyro Smoothing" or something, what is this and where do i find it? Cause my readings are quiet jittery, it rotates as if it was out of trim but after trimming it still rotates a bit...

Dont know if you guys will be able to see these but its worth a try:

First Test fly (no PID's changed):

A few later ( after changing the P alot):

which ESCs do you use?

the second fly looks controllable, lower the I term (I would try this)

 

"Gyro Smoothing" is from Aeroquad, you don't need this on Arducopter

im using towerpro 40Amp ESC's. and yes it is controllable. Could you explain what the PID settings do individually. I had a 10 sec flight today, best yet and then fliped it and bent 2 motor mounts so i'll be out for a bit...

sorry, but I can't explain it (ok I can, but nobody would understand it^^)

 

It is pretty good explained here:

I explain it as it tries to hover (so no RC commands in this example)

 

P is proportional -> the farther it is away from level, the more is it trying to go back to level

 

I is integral -> it adds up the error (so it will become more stronger if it can't go back to level)

 

D is deverative (I don't exactly know its meaning): this is the amount of dampening (it breaks before level, so it does not overcompensate)

 

afaik in stable mode the D value in configurator is in fact another P value (but I don't know it's use)

thanks man,  that sould help me dial it in perfect. I cant fly until Sunday now, i bent two motor mounts when i flipped it, my supplyer will only get them in then...
