Comes with a 1300Mah NiMh 7.2v and mains charger woudl take a few hours to charge, but I would recomend a bigger capacity battery as that one will last less than 10 minutes of high speed running - I am currently running on 2s
Comes Ready to Run with transmitter - plug in a battery and off it goes.
Straight from the box I would recommend adjusting the ride height (4 screws on on each wheel that need to be tightened down to give more travel)
Would then look to block the hole under the motor, as the brushes are exposed and the way the motor sits - dust and even the slightest moisture go straight up and cause problems. then block the holes under the battery....
I am looking putting a sheild across the whole bottom of the tub, probably the thinnest aluminium sheet I can find.
