Default lots of glitching. need some fast help

i have a scx 10 ae 2 esc, hs-645 steering servo, small traxxes servo for shifting and a old traxxas 27mhz 3 channel radio.. wires are all over.. still trying to get it all to work right then i will put wires into place.. had a hard time calibrating the esc to the radio.. finally got it or so i thought.. put it on the floor go a few feet. things glitching like crazy.. any ideas??

Running a 27mhz system is the first issue. The old am/fm radios are well known for picking up sporatic signals and causing crazy glitching. A cheap investment in a 2.4 would be my first suggestion. Also look at all the wires themselves and check for broken casings and frayed areas that may "ground out" against other metal components and cause the glitching issues you speak of. I have also noticed that when I run my AE-2 it will glitch like crazy in NIMH batteries but function fine with a 2S lipo. A couple ideas anyway. Good luck. If it ends up bieng a radio issue I have a couple spares for sale if you search my name in the for sale section.

Could it be your servo making it glitch? I know my mmp loves to glitch with most servos, but I don't know about the ae 2.

Is this with the motor running? If so, do you have motor caps installed (a MUST HAVE for AM/FM radios).

Did you try with both servos disconnected? A bad one can cause glitches.

Since it's not 2.4ghz, keep antenna & servo wires away from the ESC & pack wires.
Also, is the antenna stretched out, or wadded up? It should be mostly out and away from the ESC.

Sometimes having the motor & battery wires with a few twists on the free length (vs. straight runs) can reduce RFI/glitching.

If it is ok till you drive away it is probably a broken antenna wire. You really should get a 2.4 radio

No motor caps is likely the major issue.

Why not use one of your spare GT3B's??

Yes, caps on a brushed motor are caps, no matter if sealed or rebuildable.

You have questions, you have my cell #.
