X580 multirotor first build help!

[mfc123]

Hi!

This is my first build and I';m new in the world of RC and Quadcopters!

My current build is :

Hobbyking X580 frame
4 x HexTronik DT750 Brushless Outrunner 750kv
4 x HobbyKing 20A BlueSeries Brushless Speed Controller
Crius AIO Pro V2 with MegapirateNG
NEO-6M GPS Module
Turnigy 9x with 8-channel transmitter module DJT-II (V2)
8-channel receiver D8R-II Plus

I have mounted all and flashed the MegapirateNG with arduino and configured all.

Tested the motor rotation and corrected all like in the arducopter tutorial.

Then installed the Mission Planner and connecter to test the sensors, all are Ok including GPS.

Next I have done the auto calibration of the ESC...

The next step was to finally test how it flies... It';s when it all gone wrong!!

My quad on the take-off was flying real bad and I lost it for 10 days...I searched it for 10 days and found it :) lol

Can you please tell me what went wrong??

Here are some pics of my quad and the crash video :/

First thought is your PID';s are out ... when I used MPNG I had to use P=0.07 ish and D=0.004 ish (If I remember right) ... but I';m sure that some more experienced people will be along soon :)
