I would check CLI also to make sure.
I think setup - frame.
When I had the issue I enabled motor logging to see what was going on. I had output on motors 5&6.
Checked the frame and Bob's you uncle.

On the first MP hardware screen you select the quad.

Then on the second screen you select if it is a + or X.

That's it.

Carefully check motor spin direction and order.  Do not use super simple mode.  To test, hold the copter above your head and turn on (you don't need hover speed to do this).  Wear eye protection, thick clothing, and gloves.  Apply pitch forward to see if it points down.  Pitch back to see if it pitches up.  Roll left to see if it leans left and roll right to see if it leans right.  Yaw left to see it it goes CCW and yaw right to see if it goes CW. 

Then if it still acts funny then it is probably tuning and post a photo.  You can also start a new topic so people can directly reply.

Is there actually a way to distinquish a quad vs hexa vs octo  copter? I just saw that you pick the frame type then it has X configuration and all three fall under there. Your suggestion does make sense, but how do I set it in the CLI? Man, if this is the only problem I can start flying this thing right now. THANKS in advance! --mark

I had this problem before exactly in you video.
Copter was config for hexa instead of a quad.
Check the configuration in CLI.

yeah, I just went back to the soldering board and tried to solder it again. It looks find and I am almost certain that the TGY 9x is pushing it out. It works with a KK2 as AUX. Anyway, I took it out again with high hopes and it just dug into the dirt (same sas below only I actually let it go). Sold have filmed it but didnt have the camera ready. Anyway, not sure what to do now. Thanks guys.

make sure you have define aux-ch at your radio, and do radio calibration again.

Well, here is my first attempt at doing a hand test. I dont have anyone to help right now so I am trying to just demo this by watching what it does from the ground position.

If I was to give it more power it would just fall to its back side and grind into the dirt (this is what happened several times yesterday)

I am assuming that it defaults to stablize mode as I dont have a channel 5 switch working at present... lemme know what you think. Thanks in advance.

That may be old I think, this is new:

This is the Wiki page for Arducopter! You will find systematic and clear instructions here.

Thanks all!
