Cristian,

Mate, the only way you will fix this problem is through trial and error, or more simply put, swapping out parts one at a time as ben73 has suggested..

If you have a different radio, ESC, servo that you know works, then change them over one at a time and try it.. What have you got to loose...?

One more thing.. Try removing the covers from the ESC and receiver and clean them out, especially if you race on carpet.. It may be something as simple as a small stone / piece of dirt rolling around inside the case shorting things out on the bottom of the PCB..

Ben, do the same issues occur if someone used the low profile futaba? also would lipos cause the issue? just wondering as i'm about to buy some gear and have a similar setup, except i'd be running a 10.5 brushless with the TC. Im currently deciding what servo to use, either the futaba LP or the KO LP.

Tom

I have not personally used a Futaba LP however I have tested JR, Hitec, Sanwa/AIR and have not seen the problem. Have not heard of anyone else having the issue with FUT either.

Lipo will not cause it because the voltage whilst consistent across the discharge does not hold the initial peak.

My testing will also differ slightly as I have been doing it in offroad - however I have been running the cars on carpet inside to simulate huge traction and hence high current draw.

Its a pretty easy decision though. If you run spektrum dont run a KO servo and if you run FM then you are fine to run whatever gear you want

Ben

Have you tried changing the lead between esc and receiver?

Is it only happening when you punch the throttle hard?

Does it happen more when you turn and throttle at the same time?

Thanks guys, Ive spent the last 2 hours trying to solve the problem, things Ive tried are:

- Clean motor wires and re solder. no luck

-re position the receiver including inspecting the wire for exposed wire (none), open receiver and clean....no luck

-raising the spektrum antenna and reposition: no luck

-Put in a brushed motor............It worked no glitching.
Doesn't help as I need to use a brushed motor.

try the servo like Ben said.

if you have a mate with the same reciever i would see if you could borrow it for five min a try it out. one of the guys i run with was having glitching and he went through all the wires checking etc, when he got near the antenna wire it actually fell out. baught a brand new one and hasn't had a problem since.

thanks too twisted, Ive been suggested to try this out as well, Ive never done this to my previous motors, but its definitely worth a try tomorrow.

thanks everyone for your help, when I find out what it causing this problem I'll let you all know.

swap the servo like Tom and Ben said,
I have had this prob with my nitro cars running a spektrum a few times and once with one of my EP cars (rx switches to fail safe mode where you still have steering but no throttle) Prob has been fixed by swapping the servo with a new one
