I already have a Maxamps hardcase 5s and I'm coming from a Tekno D8. I'm actually using all of the electronics from my D8. Mechanical brakes aren't needed with a Traktion Drive setup (it's not the same as a nitro clutch setup), but I'm not worried about not being able to use it. Two more questions... Should I worry about filling the diffs and shocks out of the box, or is it good to go? Also, what's the gearing in the Inferno GT2? I'm going to aim for a 60mph bashing setup using 5s and an 1800kv.
