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?
As the battery voltage drops, brownouts on acceleration become quite evident, voltage sag. It's my understanding that Spectrum receivers pull a little more than some others. As the esc heats up, it may be having problems maintaining constant current dealing with all of the draws. Install a Bec for reliable current and be done with it.
