I would have expected those batts to cook a bit, but if they are staying cool then perhaps you are not stressing them too much. Maybe.. Could be linc is right too. IDK from the provided info.
If you back down on the speed/gearing a bit, your setup should be fine. Pavement is a pretty easy place to drive. Grass driving gets things really cooking. Use trug/maxx sized tires and that will help a lot as well. If you want more, something will have to change.
The only muggy I drive was still nitro, and it was a big fat bitch. Takes alot to get those moving. As linc describes his setup, just for mid 40s it takes a ton of power, and it works the system pretty good.
If I was doing a Muggy for mid 50s reliably, i would go 8S (30C 4000mah+), 1521, and an MGM. I like to over-engineer FWIW, but I don't blow my $hit up either. Good luck trying to keep that hellcat under control tho  |
My runs are always on a smooth parking lot - no grass or dirt (I intend to get it on dirt someday). Not running 40 series, as I don't know of a tire that can take this level of abuse in that size. I'm running HPI phaltlines, which are street tires slightly larger than standard truggy tires. I'm running a 12T pinion - 18T simply doesn't work. I can't go smaller than 12 though, it won't reach the spur. The motor temp is very dependent on weather. If it hits 170, I stop, but that only happens if the ambient is 70+. My battery has never gone past 115, and the MMM fan is almost always on, regardless of outside temp.
