sk450 banking to the right intermitantly

[paul82]

hi guys.

I recently changed my kk2 board because randomly during flights my quad would just bank off hard to the right for a while with no warning then after landing it would be OK again.

I thought everything was good with the new kk2 board but on the second flight it did the same thing again - banked hard to the right... Grrr 

so I changed all the esc around and still the same problem. Does anyone have any idea what is happening. I have 2 spare motors and am wondering if changing the right hand side motors would help

Check your bullet connectors for a bad solder joint,Marty. :scotland:

Bullet connectors all seem ok.

if you';ve swapped the ESC';s around and the problem is still the same u might as well try the spare motors u got to see if the problem follows, or swap them and round see if it starts to to bank left.
