Glitching Slash - RC-Monster Forums

Just installed a MMMv3, Medusa 36-050-3300v2-3f and 3 cell Lipo. I am using the factory radio and reciever. It ran fine stock with a 7 cell nimh and now it glitches really bad. Especialy when I give it full throdle, it takes off for about 2 seconds, then locks the tires up for 2 seconds and then takes off again. Also whin about 150' away it starts to drive its self. This is in front of my house with on others on the same fz as me.

Factory radio system is AM. That's most of your problem.

I can only gather that the interference wasn't strong enough because the NiMH cells can't produce much current. The LiPo allows the motor/ESC to draw much larger pulses of current which reach out farther from the wires and interfere with the AM radio signal. It happens especially on acceleration because that's when the motor draws the most current. Am I right BrianG?

You could try to relcate the reciever as far away from the motor/ESC as possible. Try putting it behind the front bumper just for kicks. If it doesnt help then you may consider wrapping the motor/battery leads with aluminum foil to help shield the reciever. If neither one helps then I think you need to upgrade the radio system. Either FM, PCM, or 2.4GhZ (DSM) will be pretty much immune to this type of interference.

Did you mean "with out others...."? If there are people on the same frequency then that will definitely cause bad interference.

Edit: Is the throttle trim at "0"? I did that more than once when I was using the stock TRX radio. My Rustler would go zombie on me.

Yes, I meant there are no other people running other vehicles.

The trim is at zero...I think your first post sums up the problem. I will get an fm reciever to use with an fm controller I have.
