The storage capacitor can be plugged into any vacant servo socket at the receiver, and eliminates voltage spikes which could cause interference to the receiver. High-performance digital servos generate extremely high peak voltages under load, which may damage the receiver or have an adverse effect on the receiver's micro-controller under certain circumstances. Receivers and servos are fitted with reservoir capacitors, but they are often too small to filter out these unwanted voltages. The storage capacitor effectively protects the receiver and servos from severe voltage spikes. Brief collapses in voltage are also effectively bridged by the capacitor. The storage capacitor is a sensible precaution for any airborne system, as it enhances the security of thereceiving equipment. It is recommended for use with receiver batteries as well as with electronic receiver power supplies. The storage capacitor is particularly helpful with 2.4 GHz receivers, but is also a useful adjunct to conventional receivers.
