In some cases, when using particular servos in applications that require a very long extension lead, and when powered by 2S LiXX batteries, the servos may randomly jump (glitch). Due to the resistance in long extension leads the signal voltage drops thus causing the problem. Accordingly, where long extension leads are required, it is recommended that only high-quality, twisted, 22-gauge, high strand count, gold connector leads are used and, in the event that this does not resolve the problem, this signal line booster unit will provide valuable peace of mind and, in most cases, will resolve the issue.
