Help!
Tricopter stabilisation issue

Hi folks,
Well, I'm coming to you because i have an issue with my very first multi rotor (use to fly classic helos). Even though i watched multiple videos and read multiple threads, i'm still not able to make my baby fly. Enough speaking, here's a short and dramatic ending video that explain the problem.

Tricopter yaw issue (0 min 20 sec)


For more details, if you can't clearly see what is happening, M1 is running faster (or M2 slower??), creating a yaw spin that tail rotor is actually trying to compensate.

Since i'm using 3 CW prop instead of using 2 CW on M1 and M3 only, i'm guessing if this could have to be corrected in KK2 settings ?

Many thanks for reading guys.

BTW, sorry for my higly probable language mistakes, i'm french.

Hi.

The PI settings are way to high . You need to lower the Gains on both P&I settings .
Here is a good video on setting it up

We are quite lucky in France with the "drones" flying law.

Basically, there's two categories :
Commercial activities and hobby activites.

Commercial activities : you will need Civil Aviation authorisation and Ultra Light Motorized flying licence for the heaviests models. http://www.baptemedelair.fr/uploads/...eb9ce2ae30.jpg

Hobby activites, rules are :
Being able to keep direct eye contact (meaning that for FPV flight, you'll need a second pilot with trainer port connected to its own transmitter, ready to take control of the model in direct view)
Flying in a box of 150 meters.
No hovering of urban areas.
You can use cameras as long as you fulfil the laws on privacy. You may not share videos or pictures on social medias (actually, it's quite hard for law enforcment to keep control on this).

I think that's almost all there is to say. Do not hesitate to ask for precision if i'm didn't make myself clear enough.
