Default Motor cutting out

Hi Everyone,

I have a D413 with a Tekin 6.5T motor, Orion Vr10 ESC, Savox 1258 Servo, Airtronics 461 Reciever. Stock spur with a 23T pinion.

While running it up and down my street to get the steering setup correclty. It seems to cut out frequently.

My kids B44 with a 13.5T motor was leaving me behind.

What should I be looking for to figure out why it keeps cutting out on me? Would it be a setting in the ESC? Maybe the RX? Not sure where to even start.

Thanks!

Most likely a bad sensor cable if it's just the motor. A brownout if it's the whole car including steering going "off." Try a new sensor cable first followed by a glitch buster if that doesn't do it.

^^ Excellent response once again!

I would also just touch the ESC heatsink to see if the ESC is not doing any thermal shutdowns.

Thanks Mark!

I will swap it out tonight and give it a try. What is a glitch buster?

Last night I realized that the battery I used was not fully charged. It was a pack that was still at storage. Would that cause the glitching.

I ran the buggy last night with a fully charged battery. The glitching was gone.

Another thing i noticed was that i zip tied the sensor wire with the motor wires. Probably not the best idea.

You were probably getting close to the low voltage cutoff when the car was drawing power, or the ESC was not able to provide enough BEC current because of the low voltage from the battery, causing your issue.

Correct - you were "teasing" the LVC setting. Sometimes the answer is even simpler than the simple answer.
