As standard the Hammer comes with a 2.4Ghz wheel type controller, a high precision 540 motor, waterproof speed controller and 7.2V 1800mah Tamiya type rechargeable battery pack. This setup gives more than enough power and speed for any serious racer but if you are the kind of person that likes to take things to the extreme then you can upgrade your model with a brushless kit. With the brushless motor, ESC and Li-po battery the truck will go even quicker and will take some real skill to control. You can add these upgrades above but please note they will not come fitted so you will need to fit yourself. The upgrade kit contains 1 x high power brushless motor, 1 x brushless ESC, 1 x 11.1V 2200mah LiPo battery and 1 x LiPo battery charger.
