Capacitor - Voltage / Brown out Protector

If you are suffering from radio problems, this maybe your answer. A voltage protector helps to prevent your receiver / flight controller (FC) from dropping below its required operating voltage and smooth out voltage spikes. This helps to eliminate "brown outs" and prevents your receiver / FC from rebooting. It will also help reduced the load on your ESC's BEC and reduce the likelihood of glitching. Simply plug it in to any spare channel on your receiver or if you use the APM FC, any of the 5V [+] and GND connections.
