Quadrocopter - first measurement of lift force

(Deutsche Version) Today, I measured the lift force with a motor from ebay and propellor. I used this motor (the price was 9,75) and this control unit. The propellor is a 10x4.5 propellor. The result: 238 g lift force.

The specifications of the motor are: 1200 kV, 25 A max, 18 A continuous. The specifications of the control unit are: 25 A max, 20 A continuous. This should provide some kind of general idea of how much lift force is possible with which equipment.

The measurement is the following: The motor is mounted on a frame of Lego and this frame is glued to a scale. The speed of the motor is set via an ATMega (see ), with a potentiometer connected to an analog input. The ATMega sets the speed depending on the measured value of the potentiometer. The measurement setup is the following:
