Heavylift variable pitch quadcopter

It is my first drone

Motor to motor distance : 140 cm

Rotor diameter:70 cm

Maximum size:210 cm

Weight: 1.6 kg ( esc, motors and wires) without batteries

Motors are 4 pcs http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9021

White gears are from HK450 class helicopter with one way bearing for autorotation

esc 4 pcs http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11430

Tested in the house tied to that piece couch. At full thrust it tried to lift the couch which has over 14 kg

I tried to use Arduino to level the drone but using just the accelerometer is quite hard. I'm trying now using accelerometer wii motion plus gyro combo

I filtered the data from the accelerometer using a simple low pass filter. I'm currently trying to understand Kalman filter.

I tested it outside but it failed to level the drone and have a little crash. The damage was only visible on the pipes. So I bought a new set

Is the accelerometer sufficient for the job?

I also bought a lot of sensors (sonar, barometric sensor with 9 cm resolution, gps, magnetometer 1 axis, gyro, and KKcopter controller board to replace my arduino)

  • can you get the ratings of the motors, and then plug all of your variables into the formula found here to get an idea of how much this quad can lift

  • Accelerometer is not enought to stabilize quadrotor. Main reason is that because of vibration.

    And also accelerometer can't stabilize yaw.
