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)
