You mention that you're not quite sure how I works. In a PI loop:
- P is the correction rate for the current deviation from the setpoint
- I is the correction for slow drift over time

You should increase P until you get oscillations and then back it off a bit. You should reduce I until drift becomes unacceptable, and then put it back up a little. Clearly whatever you're doing is working for you, but for others wondering exactly what the heck they are messing with when changing these values, this is what you're doing.

Are you building an army of these things? Should we all be worried?

Get them all tuned the same, put all receivers in bind mode and bind them all to the same model memory in your transmitter. Then, fly all three in unison.

uh...please post a video of it if you try. Sounds scary.

Thanks for the video, goes over quite a bit. I got a KK2 coming in the mail, still working on getting my KK tuned correctly.

I don't see why they wouldn't do it. It's a one way connection with Spektrum. The receivers are just picking up the ID when you turn on the transmitter in bind mode.

If you do this, you must post a video, no matter how disastrous the results. Auto level mode should make things a little better though, and should prevent them from getting too out of sync.

P controls how hard it tries to return to position from existing change, I is for drift over time, and D is resistance to predicted change (e.g. Inertia)
