Alright so I've finally built my quadrotor and I really want to fly. The problem is every time I try and take of it flips forwards (/pitch)...correct me if I'm wrong on the terms. Anyway my setup is as follows, Dji 450 frame, 1450k motors, 8x4 props, kK 5.5 with Xcopter v2.5 pre loaded, hobby king 30amp escs , and a 40c 3s lipo. I've tried messing with the gyro pots but I still can't get it to just fly up instead of forward and most of the time upside down on the ground I know these things don't fly themselves..but I'm very new to this and could use some advice. Thanks

I'm sure others will chime in soon. My personal recommendation is to move on to a KK2 board as quickly as possible, it is MUCH easier to setup, flies much better etc. Pretty much foolproof. I own a lot of flight controllers and I had huge issues with trying to get a simple KK board to work on two small multirotors. They flew, but they never flew well.

The way I see it, KK boards have become obsolete and for just a little more you can get something far more capable. Anyhow, that's just me, so I'll let others help you with this one.

The KK2 is a much better board, but the Old KK board is still a good board. Most likely you have either, a motor plugged into the wrong spot, motor rotating the wrong direction, or have the FC pointing the wrong way. Can you post a picture of the quad from the top? Use the link below to verify everything is installed correctly.

Thanks for the replies so far.

Heres some pics




I'm fairly sure the motors are spinning the correct direction. I verified this while building it, but I can double check just to be sure. The white arms are forward

I'm going to try the directions in the link you posted livinlife. I'll get back here tomorrow to update what happened.


EDIT: Verified that motors are spinning the correct direction and are plugged in the right spots on the board, also props are on the correct motors.

My guess would be the props, perhaps the ccw is mixed up. I did it once where had two props mixed up and it would flip forward and grind the props into my hardwood.

My favorite is when I accidentally put all 4 in the wrong spots and when I increase throttle the quad just sits there, spinning away.

There is something wrong.
On your first pic, we clearly see a Rx cable on connector M6.
All Rx cables must be connected on the same side, see picture below.

Thats the battery cable for the rx, that shouldn't cause any problems right?

The reciever is powered by the fc which is powered by the esc's if I'm not mistaken so you shouldn't need a servo lead going from your reciever up m6

Ah ok..well thats a noob mistake The question is, would that cause any issues?

"would that cause any issues? "
Of course, you need the 4 Rx channels to be connected at the right place.
Aileron, elevator, throttle and rudder.

Your FC is not in line with your quad's axis and is not rigidly attached.
That could also cause later problems.

The 4 are connected. The one in M6 is plugged into the battery "channel" if you wanna call it that. Aileron, Elevator, Throttle and Rudder are all connected to the correct spots on the KK board. I know its kind of hard to tell from the image I posted

That is a problem right there....centre the FC, and fix it securely and try again.

Ok I'll try, I used double sided tape and its really on there. I couldn't move it earlier, was scared I was going to break it. Thanks for all the help guys/gals
