Brown-Out Issues?

By the way... all of this is still with the problematic 3C radio and 300 RX of orange RX?
I didn't read back to check but that may still be your issue no matter what you do at the track.
Is it ok in front of your house , but not at the track?
Does a buddy of yours have a better radio that you could pull the RX from and try in your Losi just to see if that's the issue?
Or do you have an old FM radio you could try... anything but spectrum?

Having problems w/my TLR SCTE 2.0
I was having what I thought were brown-outs. Anywhere from 2-4 minutes into a 5 or 6 minute race, I would start having issues. The truck would just basically stop. No go, no steering. Usually after heavy braking into a corner and then attempting to accelerate out of a corner. After a second or two it would start again w/o intervention.
I was using a cheaper Savox servo (SC0251MG). Added a glitch buster cap, no help. Went to a better servo (Savox SC1258TG), no difference.
Just for kicks, I removed the fan that was on my motor (Novak 4.5t 550). No difference.
Thought maybe my ESC (Novak Havok Pro) was having issues, went to my spare, no difference.
Thought maybe my receiver (Spektrum SR301) was having issues, went to my spare, no difference.
I'm back to thinking it's the ESC. I check the temps on it after having issues, but it's always in the middle of the 'acceptable operating range'. I'm kinda at a loss now. I don't have a spare motor to try, nor do I have another battery to try (using a new SPC 6500 mAh, 65c).
Anyone got any ideas?

The pic you posted (fq06) is exactly how I had it.
I also tried leaving the red wire to the receiver in place, per Novak's literature. For that arrangement, you turn the ESC on, the right back off, to disable the ESC's BEC.
I've had issues with these ESC's. It wouldn't surprise me if it was ultimately the problem.
I wonder what would happen if I put a resistor on the red wire from the receiver, and then ground it to the battery. Give that BEC something to do...

Not familiar with the Novak process, but the red wire from the ESC should not be used. The two Bec's will fight each other and the esc's bec will lose.
So you have to turn the Novak on the off then on again to disable the internal bec? I wouldn't trust that, you probably cooked the internal bec trying to run it that way.
When I used a CC bec with my savox TG servo in a SCT I used a super short servo extension wire and removed the red lead from that.

So if you don't run the CC bec its fine? Don't run the CC bec.
Maybe I missed it where its having issues CC bec or no CC bec.
I would start back at the beginning and try a buddies radio with no CC bec and see if it runs ok.

Yes, once the CC BEC is out of the equation, the throttle issue goes away. Don't know about the brown-outs. I bet they'll be back.

If you haven't tried it without the red wire eliminated, try that. The CC bec feeding back into the ESC may be giving you your throttle problem. Don't know, never tried the CC bec with the ESC also supplying power as well... that's a no no.
Try a different radio with no CC bec, your problems may be gone.

CC with the esc's red wire eliminated right? I would not trust the Novak turn off the bec deal.

May be worth calling Novak on Monday to ask them if a cooked internal bec could cause the throttle issues. Worth a phone call.
I wouldn't be surprised if the internal bec is cooked from using the on/off/on method to turn off the internal bec and it didn't turn it off.
I just don't know if a cooked internal bec would cause your issues or if it would just not operate the servo. Maybe besides powering the servo, it is not even giving enough for the rx let alone the servo.
