Hi everyone!
I am very new to both the Arduino world and the world of electronics and RC control. I am a 2nd year Aerospace Engineering Student at University and would love some help with the selection of components for the electronics side of the 'copter.
Having studied Mechatronics I am aware of the back EMF phenomena. I am also aware that there is a need for a diode in the circuit to protect the arduino from it. I know that diodes allow current and voltage to flow in one direction (hence why they are useful for protection in the circuit). However I am unsure as to which diodes to use.
I will be using the Emax CF2822 motors, the data sheet can be found here:

however I can tell you that the motors have the following characteristics for quick reference:
Voltage max: 11.1v
Continuous Current: 14.5A
Max Current: 16A for 60 seconds.
I will also be using 30A ESC's with each of the motors.
These are the ESC's I have purchased:

I hope that someone will be able to give me an answer.
Kindest regards,
Nathan
