STEP III. Destructive test and robustness. 
These was the hardest and most expensive test as the test included intentional collision of the 
quadcopter on objects and making a crash from a height of 10Meters to test the compactness and 
rigidity of the material used, initial design included using a ply wood made frame with the 
measurement attached in the appendix, in the material did not withstand the test and they did

weight, the second material used was aluminum made of the same measurement as the ply wood, 
the aluminum had a shortcoming due to increased vibration with had an adverse effect on the 
Gyroscope used in the flight board as it made the quadcopter hover a lot. Finally further test was 
done using the HJ Frame made of carbon fiber and aluminum nuts. This frame was the most 
stable in its design and Aerodynamics design as it was well balance and gave the best motor 
angles thus giving a very smooth flight. In destructive the quadcopter was fitted with the HJ 
Frame and flight of 15metres vertically achieved, the quadcopter was crashed, after the test the 
propeller broke down, the frame arm did break but the rest remained compact.
