Product Description

Optional Hitec signal booster. These boosters are to be utilized in applications where long servo extensions are present that could potentially degrade the receiver's output signal before it reaches the servo. Symptoms of degraded signal are random jumping or 'glitching', erratic servo movement, or unresponsive servos entirely. Use one signal booster per servo, plugged directly into the receiver.

HITEC SERVICE BULLETIN

HS-20110524 HS-7940/7945/7950TH Jumping/Glitching

In some cases, when using the 7940/45/50's in applications that require a very long extension, they may randomly jump (glitch) when powered by 2S LiPo/Li-Ion batteries. Although this may occur with many systems, it is most commonly found when using JR/Spektrum type RX's, especially the Power Safe versions. We have discovered that due to the resistance in long extension wires, the signal voltage drops, thus causing the issue. We recommend that only high-quality, twisted, 22-gauge, high strand count, gold connector extensions be used. In the event that this does not resolve the problem, there are a few options. The use of a signal line booster resolves the issue in almost all cases. Another option is to solder a .22 tantalum capacitor between +/- on the extension. These solutions are typically only needed when using Li-Po/Li-Ion batteries to lower the voltage below 7 volts and is not needed when using 5-cell NiCd/NiMH or LiFe batteries.

We are aware that these are high voltage servos designed to operate at the maximum voltage allowed for maximum performance. However, to accommodate some radio systems, steps may be required to assure the above issue will not occur. Hitec apologizes for any inconvenience this may cause.
