The first run i had it set on standard and got 18 mins constant running time

The second time i used the traxxas training mode noticed a big difference in performance but only got 12 mins constantrunningtime????

Just in from another fully charged 5200 mah lipo and got 12 minutes again.

I was running them constant up and down about 100m up and back again flat out, on wet flat mud surface lots of wheel spinning etc.I would imagine there to be less of a drain onthe batteries in a race/track enviroment, would i be correct?

I would have thought on training mode i would have got near twice the running time.

Both batteries were fully balanced charged etc.

Anyone any ideas?
