Are Zippy Lipos safe with a Castle MMM Speedy?

dont know about you guys but i find my E-revo geared for 45 is plenty fast for bashing....then again im not one to just drive in straight line. to each there own but i am simply uninterested in trying to get my E-revo up to 80 mph as the only i could do with it is drive in a straight line a couple times before bringing it in to cool down....Ill take my 25-30 min of playtime as a reasonable speed any day.
