Learning to fly homemade mini drone quadcopter

this is the first video that I publish in dailymotion, coincidentally it has been a long time this video I save.

this is a video featuring a homemade quadcopter drone and I test it to fly. at that time I am very happy because my project assemble this quadcopter successfully. but for quite a long time I learned to make this quadcopter, sometimes I forget to eat even less sleep, but all the struggle was not in vain because I finally managed to make a quadcopter drone that can fly
