IF YOUR LOOKING FOR A FAST ELECTRIC BOAT--[TRAXXAS-VILLAIN 4] WILL SUPPRIZE YOU. BOUGHT THE BOAT PUT IT IN THE WATTER RIGHT OUT OUT OF THE BOX AND IT DID WELL BUT FOUND IT A LITTLE SHORT ON RUN TIME. I BOUGHT THERE SPEE SHAFTS AND PROPS- IT WASNT MUCH. AND GOT SOME MORE SPEED OUT OF IT . I ADDED FOR LONGER DURATION RUN TIME TO 9 CELL [10.8V 3000 MAH. NIMH PACKS] AND IT GOT SO FAST I HAD TO RE TRIM THE PROPS AND ADD TRIM TABS. ONE OF THERE TECH AT TRAXXAS TOLD ME THERE COMING OUT WITH EVEN A HOT ELECTRI BOAT. HAVE FFUN --SID.
