This was my first try to build a quad-copter kit.  This kit had an aluminum frame and carbon steel plates to guard the electronics.  For stabilizer, I used a NAZA with GPS module. 

 

Although this was fun to build, the entire rig did experience some high vibrations which caused a jello effect on the GoPro camera.  Technology advanced so fast that other lighter and drones were introduced to the market.  This drone had to be flown with line-of-sight (no FPV).
