I have a Slash 4x4 ultimate with 1410. and MMP and have it geared 15/54 and its setup 15/54 in the program. And I have hit a max of 60mph on 3s with body on. and 39mph on 2s. Does anyone have any info on how accurite this might be, has anyone had gps on board and telemetry? Im gonna gear up to 17 or 19 next. I know people has already said im flirting with death of my motor but I have not let it get past 137 deg so far. Do they normally have to get hot before they smoke or can it just happen when not hot?
