Futaba FU6A15501 Noise Filter Extension Cord 220mm 50-Strand  [FU6A15501]

Overview: filter extension for model electronics

This Futaba FU6A15501 extension cord is intended to extend the link between an in-line noise filter and the electronics in radio-controlled models. With 50-strand heavy-duty conductors and a 220mm reach, it provides a reliable means to reroute filter connections in constrained builds.

What it achieves: relocating the filter can improve signal integrity by distancing it from motor, battery, and ESC noise sources, while helping to organise wiring between receiver, servos, and ESCs. The product is made for standard RC electrical systems.

Fitting recommendations: avoid sharp bends and sources of heat, fasten the cable at anchor points using ties or tape, and separate signal runs from power cables where achievable. Confirm connector compatibility before final installation and inspect electrical terminations for solid contact post-fitment.

If interference persists: check earth/ground continuity, re-examine connector and crimp quality, trial alternate routing to maximise separation from noisy leads, and review the filter placement in relation to the receiver and main noise generators.
