Default R/C Glitches Heavily

Hi all,

For some reason, my car is glitching heavily. Basically, I cannot drive it b/c it glitches with throttle and steering. I changed the radio batteries and reset the ESC multiple times. What would cause this issue? bad transmitter? bad cyrstals? bad receiver? From experience, what is usually the cause of this issue b/c I don't really have spare equipment to test. I'm thinking about grabbing crystals from a friend..I don't want them to dismantle their car and borrow their remote and receiver though.

There are so many things that could be causing that, more information is needed. You could have the wrong crystals, have cut the antenna on the reciever, have the reciever too close to the ESC, have the motor and battery wires too close to the antenna...any number of things.

You can try moving your electronics around, rewiring, and separate any of the power wires from the antenna wire.

is your car shaft driven?? my buddy had this problem and it turns out his pack was rubbing the drive shaft and short circuting the battery and causing it to glitch

Interferrence can come from a multitude of places. How is your antenna mounted? close to any power cables? There are three items you never want to forget,
(1) Never overlap the antenna on itself. Shortens range
(2) Never run your antenna parrelle with power cables.
Capacitive coupling induces white noise.
(3) Always make sure you antenna base or holder is real
tight. plain old vibration.

If you are running a brushed setup you'll need to check your motor for the following problems
(1) Brushes arching on the motor comm.
(2) Motor capacitors broken or missing.
(3) wire connections to the motor. Bad connections will
make the motor pull highter current thus making more
(4) Check battery connections.
(5) Receiver location, how it is also mounted.
(6) Crystals are usually the last to create problems, unless
the cases are dented in or rusty looking.

Since I don't know your model Transmitter/Receiver you can at least check these items first.
What type system do you have? Give us some more decent info so we can help you out better.
