-Battery
-ESCs(4) (one for your motor)
-Control system (Arduino, with gyro)
-Propellers(4) (Depends on size of frame and weight)
-BEC (5V for Control System)


-And, don't forget those blinkies
-You put those together and you have a UFO when flying at night!

I'm going to add that brushless motors are a must. The way a brushless motor operates makes their speed much more controllable than a brushed DC motor.
There are also ESCs with a BEC built in that provide power to your flight controller.
