Read his posts is always quite interesting ...

I may transform one of my KK2.0 into a little digital OSC ... but ... too lazy for do coding on my spare time ... maybe HappySunday can do it for us .... who knows

My problem is that I got too many RC toy to experiments .... click on pay pal is too fast compared to do the rest

Thanks for your advice

I was using a HobbyKing Orange RX6 channel receiver.

For Spektrum receivers:
You bind your receiver first then you make changes to transmitter settings ( like reverse changes , servo travel changes , etc), so you should always after changing settings on DX6i for your model rebind your receiver so the fail save of the receiver knows the proper new settings !!

Here a flight video of my KK2.0 with HK DJI PCB frame i hope you like it

To all in the East Coast, stay safe! Keep those KK2 boards nice and dry at home.

Good thing my quad is acting funny, might be tempted to see how it flies in 40mpg gusts

I had this problem. NOT ALL ORANGE RECEIVERS ARE FAILSAFE EQUIPED. Look at the HK site and you will see a 7 channel Orange receiver that clearly states "with Failsafe". The others do not have the feature. Also the low end Spektrum (3000 series I think) Park Flyer receivers don't have failsafe. The only Spectrum receiver I have with Failsafe is the 7000 (maybe 4000) model with the remote receiver. It came with my transmitter.

I also don't see it mentioned here too often and I didn't realize I could ""SAFE" the KK2 (and the KK v3) by simply moving the rudder full left at idle. I have had a quad with all the props on go full throttle after I decided to see what would happen if I turned the transmitter off. I was of course holding the quad over my head. It takes a few seconds for the throttle to go back to idle after you turn the transmitter back on.

I suggest everyone try this on their models. I can't imagine watching my quad disappear into the sky on a failure. Or have it jump up in your face after landing because you bumped the throttle while walking with your transmitter on a strap.

Nice flying there MEX

New to the whole multi-copter scene. Bought the kk2 FC.....now much reading to do

Thanks for the info.. i have already seen this.. maybe it would be more interesting to see how this method is used on multicopters.. (which parameter reads what sensor.. etc...)

Im fairly new to the KK2, but I have flashed it and it flies OK, I am trying to tune it now and notice that when hovering say 4-5 feet high, it sometimes surges and thus climbs, it seems to not sit at the same level for long. Drift seems not so much an issue as the surging...

Is this settings, or vibrations (either in props or FC) or something else maybe? Currently I have "P"75/100 "I"40/40 Height damp 10/10 no auto level not used (on aux- switched off)

This happening because of height damp values... at least this happens to mine... and noticed that happens if you put sudden yaw input! Try to alter these values to get better results.. i am thinking also to adjust my TX throttle curve to find a better 'sweet spot' for stable height...

These setting you have now ,are they what you came to after tuning your P and I gain in the proper manner?
It could be just your movements of your Thr stick? Trying tuning like posted in the First page and check out the tuning video.

In a Nut shell

Turn your Hight damp and limit to 0 for tuning...

Turn your I gain to 0

Bring your P gain up 5-10 points at a time until your see the fast oscillation. Once you do, back it off until it smooths out.
Then start bringing your I gain up.Seeing you are at 0 start at 50%of what your P gain is. Then same as before start up'in ituntil you see the oscillation. But this time it is a slower, more like a wobble lol

So once there, back it off as you did with the P gain.

Then you can set your Height damp and Limit back to how you like.

That should workout the prob you are seeing ,unless it is your Throttle movements.
Video may help ;0)
