Voltage is not the problem. The motor could handle 12 volts without problem if the load wasn't too high. It's load (amperage) that burns things up. If the motor is getting hot, go to a smaller pinion.

The problem has nothing to do with the battery. The titan motors don't have a spring to hold the brush against the comm like a normal motor does. There is very little pressure for the brushes and when you get the motor really hot it fatigues the metal and it looses tension so it can not make the brushes contact the motor properly. I've seen people do it with 6c batteries also. You must get the gearing right to keep motor temps down or you will continue to do the same thing regardless of what battery you run.

The ones i have seen fail were from not following the instructions and running the crap out of it the first pack. I dont remember the exact wording but your supposed to take it easy the first pack to break the brushes in. If you dont break them in then what happens is that the sharp edges of the brush get to bouncing into the com and eventually pulls the brush off the spring that holds it in place, no brush = no go! It was said above that it has nothing to do with the battery!

Sounds to me like maybe it was over geared The part where it says the motor got really hot kind of gives it away.

it handles 7c just fine. In fact, most of the folks that race at our local track runs 7 ( www.ocrcraceway.com )

Yes, everyone at my track too, except the guys running LiPos.

I have heard this kind of "the sky is falling" warning so many times before. It is amazing how it never occurs to these people that maybe they are the ones doing something wrong.

when you say 6c and 7c are you referring to "number of cells in Nimh" or the "C rating" of a Lipo?

Just about everyone at my track runs 7 cell in their Slashs with no problems and they been racing them for a few months now , twice a week .


Maybe the title of this thread should be , Warning - User error will ruin the motors .
