Loosing power

[Nic8]

I have a question, I am running 1/10th touring car 17.5 blinky and about 4 minutes into the race I loose power.
I can then be runing the rest of the race with full trottle but slower, so the question is, is it my esc, battery or motor.
The batteries have great punch to begin with and it happens to both, I did run a couple of meetings without balancing them, could it be they need a discharge and recharge to sort them out.

Cheers.

what esc you running. It sounds like you may have a dodgy censure wire. Some esc will run in censureless, this feels like a drop in power. It may be the wire or the censure board on the motor. Or the esc or motor is thermalling (over heating).

Cheers for the reply, I am using a hobbywing v3. I'll try a new sensor lead.

In my opinion it seems more a thermal or battery issue. Are you using a fan on the motor? And on the speedo? What ratio are you using? What lipos?
Best regards

I am using a fan on both, the esc own fan and a 40mm on the motor. I am geared at 3.43 FDR.
They are different batteries, one a gens ace 5000mah 50c and a Turnigy ultimate 6000mah 90c.
The esc has the 4 capacitor option.

What is your motor temps? 3.4 is low for some motors what is the EBT that may be your issue, I use G force motors and like them, they do not like 40* + timing and less than 4fdr so I work with it in 17.5 but I like the consistent feel. Some like more and less
