Bloody interference!!

[Hog]

More of a rant than anything.

I've started getting interference at my local indoor track. A few weeks back it caused me to hit the wall sufficiently hard to snap my ZX-5 chassis in half

Now I have the KMC conversion in place - I pulled out of all 3 of my races on Wednesday night rather than risk having it happen again. Seems to be the same place in the hall, week in, week out, near an electric socket, but this is normally on a straight so going flat parrot. The interference is affecting the servo and the ESC making the car a real handful for a few seconds each lap.

It's odd because I've not changed anything in the car - apart from the addition of a PT. Wednesday night I tried different crystals, different receiver, and with the PT unplugged, as well as moving the receiver and PT around in the car - all to no avail

I suppose all I can try now is a process of elimination - will try a different transmitter this coming week, different servo, then different ESC. Current setup is KO Esprit Vantage II, Sanwa servo and Robitronics i-Cube ESC. Receiver is LRP but that's now been eliminated from the problem by trying a KO receiver. The dumb thing is I raced outside the other weekend and had no problems at all - so it must be something in the hall. Whether something in my equipment is starting to deteriorate and is now susceptible I just don't know

Why is interference so hard to track down! A broken wire you can spot a mile off - but interference is like

Oh well - rant over - please return to normal service...................

Just a quick "open" question for you all.

With the SMT technology on the stock motors we use these days - is it possible that the motor could be at fault? i.e the capacitor board on the endbell not up to the task of suppressing the comm if it needs a skim and some brushes?

Yes it sounds like the motor to me

Schottky diodes can cause interferience, try replacing that too.

Wouldn't that have shown up outside too?

Indoors we run 27T, but outside I was using a 10x1 V2. Might get the motor skimmed, new brushes, and solder the board on before trying anything else.
