Quad multiwiicopter spider x quad issue

Ok here is the problem I just put this quad back together. But now when I throttle up to lift off it keeps wanting to flip ovee towards the front.. all the esc wires are all in the right place all motors are spinning the right directions. .. anyone have any ideas?
 
I had this problem a while ago with my grandsons hubsan x4, I sent him loads of spare blades and he put the blades on wrong. 2 were pitching up but the other 2 were pitching down causing it to flip over....just a thought

Are you absolutely sure you have the board orientation correct and motor numbers right.
Have you updated the firmware on the board or changed any settings?
What does it do if you hold it (carefully) and bring the throttle up enough to spin all of the motors up then dip each motor.
The one you dip should speed up.

Post a video if you can, someone may see something you have missed.

I had the same problem with Camerons quad.Never got to the bottom of it:(

What did you end up doing with that quad. Maybe it's Naze32 time. :)

Flipping over will be either,
Aile Elev backwards.
Wrong orientation of the board.
Motors spinning the wrong way.
Prop on the wrong motors.

Or gains WAY out, my HK AIO Crius clone with megapirate broke several props before I figured this out.
Never did get that to work properly.

I am beginning to wonder whether the crash has damaged the FC board.
Can you run the motors from the PC software?
If so I suggest removing the props and run the motors one at a time and make sure the correct motor actually runs.
Maybe the servo wires from the ESCs are hooked up wrong to the board.

Is this the board you have, if so check it, then check it again just to be sure. :)

Everything is connected correctly and spinning the right directions.. question does the gps mag compass have to be level if it does and it isn't can that cause it to flip?

I cannot be 100% sure but I would not think it matters.
I think it would rely on the gyros/accelerometers for level.
Why not just disconnect it until you know it flys.

I think you need to CAREFULLY do the hold test.
Or maybe do it with the props off initially to see if the motors respond properly.

Rudder is working right but elevator n aileron were working opposite each other when I move elevator the aileron would move and vise versa . I switched the signal wires around between the two on the rx and everything is moving the directions it is supposed to now... only issue iam having now is the cg now

Does it still feel like it wants to tip with the hold test?
CG on a quad is generally just a matter of moving the battery around, what makes you think it is wrong?

First it was connections I fixed that. Now it flipped backwards and the pack was towards the back. Before I only had a 3s 2200mah pack now it is a 4000mah pack
