MultiWii

Hi there,
i am new here and i hope that we can learn from each other and create great things. So we just startet with our tricopter and i think that we connected something wrong or even havent configuratet the multiwii code right. we hope you can help us.
So our Setup:
- A arduino Mega
- 3 NTM Prop Drive Series 28-26A motors
- a q brain ESC
- a turnigy 4.0 4000mah 11.1v 30c lipoly battery
- a mpu6050 Gyro/Acc/thermometer

we connected the escs to the pwm ports 3,5,6
the mpu6050 is connected like this: Acc -5v, Gnd - gnd, slc - Analog in 5, Sda - Analog in 4, int- pwm 2 (probably wrong)
we deleted the comment lines of #define GY_521 and of course set tricopter in the beginning.

so nothing works for now. can someone help us?

You deleted the line? I always thought you put 2 / in front of a line to deactivate it?

Did you. Run all 4 power wires to the FC? You should only need a single power input from the esc. I believe you can fry the board by running all 3.
