I have run my 6800 on a 4s lipo geared 20/55 in my 18T and all I can say is........... WOW! It never ran over 180 either.

One funny thing is that now I got a kyosho half 8 st and I put the 6800 motor in it and found out that it doesn't like bigger cars. Got the temps on the motor up to 310:005:. I think the motor is toast...
