Fast as can be on 2S, too fast on 3S! Great range, tough as a tank, this truck is a blast to drive around the yard or down your favorite neighborhood trail!Only complaint the included 1050mah hardcase batteries go quick! 15-20mins maybeProbably want to grab some 2200mah batteries about 33mmX100mmX18mm or smaller, some shorty 3S packs from Ovonics are supposed to fit but wouldn't under the battery hold down. The WL toys 2200mah 2S batteries have been shown to fit by others, will have to order some that size!
