Its very unstable and uncontrolable.
In the setup i have:
Turnigy Multistar 4822-490Kv 22Pole Multi-Rotor Outrunner
•••••••••••••••••••••••••
Flycolor 20 Amp Multi-rotor ESC 2~4S with BEC
•••••••••••••••••••••••••
Hobbyking KK2.1.5 Multi-rotor LCD Flight Control Board With 6050MPU And Atmel 644PA
•••••••••••••••••••••••••And a Carbon fiber prop i know is fit for the job (t-mount)
•••••••••••••••••••••••••And a 3-Cell 1650mah 35c battery.


But please answer i would love to solve this problem!

Hi mate Ok all looks good I would say its the KK firmware , reflash with steveis1.8s1pro its super stable , after this we can set up again and make it run really nice for you
we will need more info on the set up with the transmitter also does it fly at all or flips before take off

Have you balanced the props? That made mine un-flyable.

 

[Johan Brann]

Holtniel; how do i reflash it?
Because it has no USB ports.

It's no problem with the transmitter and receiver; and it does fly but its bouncing in the air and on take-off its hard to lift it Off because its so unstable

Pardon me, it does actually try to flip on take off

 

[GJH105775]

It tries to flip? Does it take off at all, or does it immediently flip? Also you need a USB-ASP programming cable, the KK uses the 6-pin type

 

[holtneil]

Hi mate If it flips on take off its not right check the props are the right way up and on the right motors , motors are spinning the right way
front left ccw front right cw / back left ccw back right cw , also make sure the motor lay out you loaded is the right one ,once its flying if then its unstable you need to adjust gains but it will take off and not flip so address this first

With This

With This

That is an 8 pin version, for the KK you need one with the 6 pin converter.

You sure it won't work? Look close at the connector, the wires are only going to the first three pairs or 6 pins. The last pair, 7 and 8 are empty (not being used.)

Oh well better safe than sorry.

I see what you mean, it will work, they make a lot of 8 pin ones, BUT the one you listed is a 6 pin one where they just stuck a 2x4 connecter on. So I guess it would work, it even says for the KK board.

 

[holtneil]

Hi guys the first 6 pins are the same on the 6 and the 8 , but you need the 8 the USB end if you want the ESC flash tool to go with this
