Ok, My buddys has Slash and has ben having a nagging problem with it.
It's a intermitent problem, the truck just dies for a couple seconds and then suddenly resumes normal driving with no apparent reason ? When the truck dies there is no steering, no F&R nothing, act if the battery is unplugged.

I've got rid of the stock AM in favor of a TRX 2.4, ditched the Velineon ESC for new Sidewinder, The Velineon motor was next and was replaced with a brand new Turnigy 2300kv running on 3s 5000mah ThunderPower 28c packs. Everything runs ambiant temps never any heat. On a hunch I thought maybe the stock servo? I replaced it also with a JR650 and STILL the problem persists ??? Slash Poltergeist

When the truck craps out I have yet to be able to catch it in time to see if the ESC has any lights on, it only stays dead for 2-3seconds. Can't duplicate during bench testing.

Any body have any ideas ?
The only thing I can think of is it could be is one of the Deans plugs are bad.

Sounds like probably a bad solder or connection somewhere. You would think if the esc was taking a dump you would still have steering. Sounds like power is completely cutting from somewhere.

are u running the battery pack everytime? check all solder points to ensure good joints were made

One of the first things we examined when this problem started.
Thank You

I really examined the AM system he had in there and the antena wire was really busted all to hell so I'm gonna look over the RRX 2.4 wire as well.

Are you using the same lipo every time?

A-HA !
There is a cut on the 2.4 RX wire also. VERY HARD TO SEE. The TRX 2.4 RX wire is designed like a COAXIL cable with a super thin 5-6strand center wire with the outer wire braided with a semi hard exterior coating that cracks when bent excessively.(junk) The exterior wire was cut very cleanly and my old eyes needed a magnifying glass to see it. It's repaired and working normally. Was a serious bastard to solder, now the antenna wire is on the outside of the tube with a couple layers of heat shrink to protect it. Gonna half to run inside under the body now,but it's all good.

Thanks for the effort guys !
