Yeah thanks mate, I told you not to mention that
The cells went off toward the end of the race, but it's understandable with all that drag - the ESC got to 11 flashes which is three less than I've had before, so it got HOT.
I was running 35t black pulleys front (oneway) AND rear that day - so I guess that is 11.8 overall looking at the chart, which sounds slightly over geared to me - I will double check to make sure I've not got a 15t on there instead - but I have swapped out the larger rear pulley for the smaller one, which has effected it I guess.
