Quad Flipping On Takeoff (Newb School Project)

hey guys I'm in high school and for my engineering project I'm making A quad.

I'm using 1000kv motors, the hobbyking tx and rx, a 5400 mah battery, 30a escs and the kk2.1.5. I calibrated the escs and heard some music so I think it's all synced together but I noticed some stuff when trying to take off. Bottom right motor is spinning faster and when I turn one of the knobs on the transmitter it slows down but I don't think they're all the same speed. Then when I takeoff the quad is stronger on one half than the other so it flips over. Any advice the project is due next week :/ .


Thx

Props, check that your motors are spinning the correct directions, and that the props have the leading edge going forward. If this is not the case message me and using skype, or google hangouts I can help you troubleshoot it.

Just checked and they're in the order you said. One thing I keep noticing is that two of the motors are spinning faster and that side is the one that's flipping . Maybe I'm not calibrating the escs the right way?
 
Hi mate if you go into mis menu on the KK there is a min throttle setting this is default set to 10 if you up this till all motors start and stop the same time max is 20 , also make sure the quad is 100% level when you calibrate the sensors as this is what the KK uses to know what level is
Hey i did that and calibrated the acc again I'm gonna try to fly it
 
Hey I zeroed out roll and aileron in kk settings and now it's taking off!
 
So after the first takeoff I played with the trimmers on my transmitter and now the quad isn't taking off anymore. I also messed with the pi editor. Could someone tell me what their pi values are for the kk board ?
 
The KK has a factory reset this will put it back to the start,
I would do this and set up again but this time go into monitor screen and use sub trim to zero the channels out
If you can get the flash tool re-flash with Steveis1.8s1pro frimware its much more stable to fly on
I don't think I can flash it but I can reset it and try again
