Fabrication and Testing of Scaled Prototype of Hoverbike

Published on Nov 30, 2023


The Hoverbike prototype is one-third scaled model of full sized Hoverbike (manned). This is an attempt to develop a prototype having propellers that are driven electrically incorporating tilt motor mechanism, wherein servo motors are used to manoeuvre the model. The objective is to fabricate a light weight prototype that consists of a payload bay, achieve longer endurance and range, decrease the cost, utilise less power to achieve lift, provide longer battery life, reduce programming steps and be simple in design compared to the existing drones. Based on the idea of existing four propellers, a research based on trial and error methods was made to develop two propeller Hoverbike. The fabricated Hoverbike prototype had a weight of less than 1kg. It could fly at a range of around 800m within the range of remote control. An endurance of maximum 5-10 minutes was obtained. The payload obtained in case of two blade propeller was 0.3kgs and in case of three blade propeller was 0.5kgs.


A Hover bike can be defined as a combination between a motorcycle and a helicopter. That is it has the simplicity of a motorcycle and the freedom of a helicopter. Ideally, such a vehicle would be able to allow people to navigate the earth in a new and unique way. The Hoverbike flies like a quadcopter, and can be flown manned or unmanned, while being a safe level - low level aerial workhorse with low on – going maintenance. It is easy to operate and can be applied to various purposes because it does not need a runaway and is capable of hovering from any terrain. For this reason, the military has shown continued interest in hover vehicles. A Hover bike is mobile and can be deployed rapidly. Also, it is aerodynamically efficient because the lift generated by the duct can create a thrust force that is higher than the other VTOL (vertical and/or short take-off and landing) vehicles, which have no duct and therefore no hovering flight mode. In the case of the ducted-fan type flying bike, its rotor is covered with duct which lowers the risks of rotor damage caused by tiny bugs and foreign object. To date, there are no commercially viable Hoverbike being built, though some test prototypes do exist and are in development .

Devices and Specifications


Standard of Equipments

Flight Control Board

The control board controls the automatic regulation of Hoverbike balance with the gyroscope induction system. The KK2.1.5 is packed with new found power with updated sensors, memory and header pins.


An ESC is an electronic circuit with the purpose to vary electronic motor speed. The throttle of each ESC is controlled by a separate channel and has a gyro between the receiver and ESC.

Electronic Speed Controller


A “Universal Battery Elimination Circuit” is an external electronic circuit that taps power from motor’s battery pack and regulates the voltage down to the necessary 5 or 6 volts for the receiver and servos.



Frame Design 1

Figure 3. Initial fabricated prototype Based on the calculations, a CAM sketch of the prototype was designed. Assuming the weight of the model, initially wooden strip was selected for frame and rudders. Four servo motors were connected to each rudder. During the first test, model didn’t lift from the ground as the weight of the model exceeded 1kg.

Frame Design 2

For the second design, two servo motors were used to reduce the weight where two pair of rudders on either end was operated by just two servo motors with the help of linkages. During the test the model used to flip towards either left or right and would crash just after takeoff because of instability. This was due to the lesser surface area of the rudders. 7.3.

Frame Design 3

For the third design test, to increase the stability, the surface area was increased by providing ultra light plastic duct which increased the weight of the model by some amount. The flight was unstable again so we dropped the idea of rudders.

Frame Design 4

For the fourth design, to gain better performance, the concept of tilt motor using servo motors was used. Two servo motors were used to tilt the DC motors on either end for the desired angle during flight. These servo motors were connected to the DC motors using linkages. Reprogramming was done. The stability slightly increased. In order to improve the stability further, we tested for many trails, each time implementing new changes.

Frame Design 5

For the fifth model, to provide safe landing, an inverted T shaped stand with certain length and height from the ground was fixed to the prototype and was attached to the frame as shown in the figure which lifted the model by 10cm from the ground. The stand was made up of aluminum and thermocole was added at its bottom for the smooth landing. During flight there was oscillations created by the stand which used to increase for each cycle which caused the model roll uncontrollably and crash.

Frame Design 6

For the sixth design, to achieve better stability and smooth landing, a stand made up of wood with larger length was directly attached to the wooden frame without providing any vertical distance from the frame to the ground which is as shown in figure below. Sponge balls at the ends were used to obtain smooth landing. The payload bay was created using ultra light cardboard material. The required stability was almost obtained.

Advantages and Disadvantages

The most obvious advantage of Hoverbike is its low cost, because it is significantly cheaper to purchase, fuel, and maintain than regular airplanes. Hoverbike is significantly easier and faster to deploy than most alternatives. It can perform precise, repetitive and hard tasks and can also fly in hostile conditions. Most importantly, it is smaller and can fly lower than traditional airplanes, therefore reducing the risk to military hardware. Unmanned vehicles may not have the same reaction time as manned vehicles. The flight actions are more difficult when using a camera and remote system. Battery power could be limited. Also the camera footage is not as reliable as the naked eye.

7. Environmental monitoring.

8. It has the ability to carry supplies if extraction is impossible.

9. The full scaled model could be used as a future mode of transportation.


The designed light weight Hoverbike could successfully achieve lift and stability during flight. It could fly at a range of around 800m within the range of remote control. An endurance of maximum 5-10 minutes was obtained. The payload obtained in case of two blade propeller was 0.3kgs and in case of three blade propeller was 0.5kgs. According to our model the fabricated design was suitable for general purpose and hence this fulfilled our goal.
