Quadcopter is a helicopter that is lifted and propelled by four rotors. Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counterclockwise (CCW). These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust.

Quad plane is a hybrid drone which is a combination of fixed wing and quadrotor. This combination gives it vertical takeoff and landing capabilities infused with a long endurance flight. This combination also enables the plane to hover at a given gps location and do a static payload drop. This configuration is best suited for post disaster operations where the availability of runway for takeoff and landing is scarce and the relief operation requires a precise payload drop.

Fixed wing drones are fixed wing planes with autonomous mission capabilities. Drones are equipped with GPS and compass modules that helps it to fly autonomously based on gps coordinate values. The second phase of the project was the inclusion of autonomy to the rc planes. This was achieved by using Ardupilot 

Fixed wing RC planes are small flying machines resembling a fixed wing plane which are controlled using radio transmitter. Broadly RC planes are divided into three different classes based on wing loading, which is the ratio between the all up weight and the wing area. The classification are glider, trainer, acrobatic and racer.
