The lower part of the saucer body has been built using high-density foam for greater stability and withstanding the torque from the motor. The upper part has been designed using low-density foam to decrease the weight of the design. A 2840 kV brushless outrunner motor is attached to the motor mount, at the bottom of the saucer. This motor creates a high lift for the saucer. The motor is connected to a 30 amp electronic speed controller, which is connected to a 2.4 GHz receiver. A 2.4 GHz transmitter is used remotely to send signals to the saucer. Different channels enable us to alter speed and change the direction of the saucer. The rudder, which is connected to servos, helps us to change the direction of the saucer.

WORKING

The receiver gets the signal from the remote transmitter, which turns on the motor via an electronic speed controller. The electronic speed controllerthat is connected to a particular channel on the receiver. The servos for controlling the rudders are connected to other channels of the receiver. The saucer is powered by a 7.4 V lithium-polymer battery. Once the motor is turned on, we can control the speed of the motor using an electronic speed controller. The propeller, which is connected to the motor, pulls the air downwards from above the saucer, which creates an upward lift for the saucer.

The RPM of the motor is directly proportional to the lift created. When the rudders, which is connected to the servos change its direction, it creates a pressure difference on either side of the rudder, which makes the saucer to move in the direction with the lower pressure.
