Quadcopter Project Exploration
What started as an Arduino computer-programming class project, later became a passionate and obsessive flight performance improvement-project.
MK1
 
 
MK1 (Ardunio Quadcopter) was programmed by me with a simple code, no gyros were used, and the accelerometer was disabled for the flight on the day of my final. The entire object was balanced so it was able to hover without getting out of control with a couple of inches of clearance from the ground.
The flight time was very poor (under 2 minutes) yet very exciting since it was the first project I built that was able to fly, and considering I had no previous experience with either quadcopters nor programming.
MK2
 
MK2 was a later version that I made using a kk Board. I used the same components but the frame changed completely making it a more sturdy design and reinforced arms). I brought down the weight dramatically by getting rid of the extra (for the Arduino), some unnecessary and . Yet I included a "landing gear" which brought some weight back.
I was getting around 3-5 minutes of flight time.
MK3
MK3 is my latest improvement. I removed the landing gear and replaced it by bending the extremities that were earlier useful for training (to prevent the propellers from braking every time I crash-landed). I also upgraded the 3 cell 11.1v battery from 1500mah to a 2500mah.
These improvements translated into longer flight times: 7-8 minutes
The Goals:

Originally the project goals were to build a quadcopter and make it hover. The goals later changed as I became more familiar with the technology and available parts.

The new goals were to improve flight time gradually without surpassing the $200 overall average price range (including parts, frame, battery and radio), to reduce the weight as much as possible, and to maintain a stable and agile flight performance.
