Thanks for pointing that out. I missed that.
From what I've read though, a brushless motor shouldn't be hitting over 80 degrees c/180 degrees f. Is that right? If that is the case I'm at the limit now even though I'm running longer gears (I assume because I am running 0 motor endbell timing (As I have no idea what I am doing with it I haven't touched it) I haven't blown the motor).
I just want to take it down a notch to keep things safe before I do any damage (hopefully I haven't already). I want to try to keep the ratio of 4.2 as typically people run 3.9-4.2 at my track. So I want to work around keeping the ratio of 4.2 or maybe push to 4.3 at most if I have to.
Obviously it is cheaper and easier if I can play around with the esc settings instead of buying more pinion/spurs/cooling if I can drop temps as effectively.
What I don't understand though is what out of all the settings should be the first thing I should look at to drop the temperature of the motor?
I know I can go to the track and try find this out through trial and error but I have hit 80-82 degrees twice now after 5 minute runs and I don't want to further risk damaging the motor.
At least then if I change some esc settings, if I see the car lose too much performance by the change I can look at extra cooling/gearing to see if they might drop the temps down while not reducing performance as much.
Also I feel I'm very close to that sweet spot right now given that the car didn't feel like it faded despite the high temps. So I think I just need 1 more change. Just don't know what.
