Glitches with Steering

 

Have you had unusual glitches with your steering? This may require additional information to troubleshoot.  Below is a couple things that could be causing the glitching.

A “glitch” is any type of interference that reduces (or eliminates) your ability to control your car or truck. This interference can come in many forms; it might be a slight hesitation to respond to a radio input, or a severe glitch that causes your RC car to twitch. Hunting down the cause of a bad glitch can be frustrating, but don’t lose patience; the glitch “hot spots” are well known, and most can be eliminated by methodically checking them all.

  1. Check receiver and transmitter voltage.
    • First things first: does the transmitter have enough juice to pump out a strong signal? Always keep fresh batteries in your radio.
  2. Check and Adjust your Trim Settings on your Radio
    • One of the first steps would be to adjust your ST.TRIM buttons.
  3. Protect the receiver from vibration.
    • When it comes to preventing glitches, vibration is enemy number one.  Keep the receiver away from the motor or engine. Receivers are great “listeners,” so keep them as far away from electric motors as you can. It’s also best to mount the receiver on its side with the antenna side facing upward.
  4. Use grommets!
    • Like receivers, servos are also prone to glitching because of vibration-induced damage, Whenever possible, install the rubber grommets included with your servos to reduce the vibration that is transmitted to the servo case.
  5. Route servo wires away from danger and check the plugs.
    • Exposed servo-lead wires and broken connectors are easy to overlook. Over time, the insulation around the servo wires may be rubbed off or torn if the wires rub against the chassis (and if they’re in contact with moving parts, they’ll be shredded almost instantly). Check the wire harnesses for wear, and carefully inspect the plugs; sometimes, the internal metal sleeves that interface with the receiver’s pins may get pushed out of the plug. If this happens, they’ll make only intermittent or partial contact with the receiver pins, and this will cause glitching.
  6. Inspect the receiver and transmitter antennas.  
    • If the receiver antenna is cut or damaged, have it replaced.
  7. Try Your Transmitter With Another RC.
    1. If you have another RC of the same frequency as your transmitter, try using the transmitter with that RC to see if the problem is in your RC itself or in the transmitter. If it works, the problem may be in the original RCs receiver.
  8. Try Your RC With Another Transmitter.
    • If you have another transmitter of the same frequency as your RC, try using it with your RC to see if the problem is in your RC or in the original transmitter. If it works, the problem is probably in your original transmitter.
  9. Check Your Servos.
    • The problem might not be in the radio system at all. It could be that one or more of your servos have stopped working. One sign that the problem is in your servos is if the RC responds only to some commands from the transmitter but not others — for example the wheels will turn but it won’t move forward. Try unplugging your servos from the receiver and plugging them into a receiver that you know is working (be sure to match the frequency of the receiver and transmitter). If the RC still doesn’t respond then your servos, not the receiver or transmitter, may need repair or replacement.
