The BEC is the 6volts that the speed control (tekin rs pro in your case) supplies to the receiver down the 3 wire cable that you plug into your receiver. This power is used to power the receiver and the servo. Sometimes the servo can draw to much power under use which makes the voltage drop and the receiver turns its self off which causes the car to stop until the power recovers and then it it starts up again. The capacitor (voltage protector) that you can plug into the receiver stores a small amount of power so when the voltage drops the capacitor unloads its power into the receiver and stops it from turning its self off. The receiver capacitor is only needed if the car is stuttering or briefly losing connection with the transmitter.
Hope this helps
