Long servo leads can function like an antenna, picking up electrical noise and interferance. This "Noise" is carried directly to your receiver! This device blocks all noise and amplifies the servo position pulse signal. Micro sized circuit. Just add your plug to provided wire or splice into your extension/Y harness. Great for long runs to reduce glitch and interference problems. 4.8V systems only.
These Toroids are intended to be used as shown in the picture. They will reduce or eliminate high frequency pulses (radio noise) from a wire. Wrap at least 3 times. Uses about 1 1/18" wire per wrap so order your extensions to allow for an extra 3 3/8 to 4 1/2".

Radio Plugs and TX Power Jacks
Powering and charging a transmitter through its DC port takes the correct plug for the brand and jack size, and this category collects radio plugs, TX power jacks, and matching sockets for the common systems. Matching the connector to your radio avoids reversed polarity and loose fits.
Futaba and JR/Spektrum Fitments
Plugs and sockets are offered in Futaba J and JR/Spektrum styles, in 2.1mm and 2.5mm sizes to suit the DC charge jack on each brand. Both inline and panel mount versions are listed, so you can wire a lead or build a port into a case.
Charge Connectors
Dedicated charge connectors, such as a Futaba transmitter charge and power port plug, round out the selection for keeping a radio topped up between sessions and ready for the next flight without hunting for the right adapter.
