Revo and 1515 2.5d

[E-Revonut]

I assume that you mean two of those packs in series for a total of 6s. Thats pretty conservative gearing, less than 35MPH. I have run that motor in my revo on 5s geared higher and it's fine. That setup should give you low temps on everything. I would gear it up a little higher though, either step up the pinion or get some smaller spur gears, I'd recomend getting a bunch of different spurs since they are so cheap. Anyway you do it it will run just fine, it's an awesome motor
