yes if you buy it ''Traxxas.com"!!
overall stampede 4x4 or rustler vxl prob 4x4 stampede
yes
The best place to buy a traxxas bandit vxl would be at advantagehobby.com
NO!
of course
It depends which Mamba Monster you are talking about. The Mamba Monster 2 2650kv is faster than the VXL
3mm
the rustler is better for speed wise but the stampede is good for bashing but both of them are nice it just matters what you are doing with it
the stamped is brushed and goes 30 mph and the stamped vxl is brushless and can go 65 mph. the are both good but the stamped is good for beginers i know i have on and then put brushless on.
Buy a aftermarket lcg chassis
It can be, but I would upgrade it with some tape and filling just in the plug to water proof it. If its a brushed motor do NOT run in in mud or water. That just ruins the brushes then it won't work. Nor Brushless don't run it in it rather, or have fun buying another VXL system.
Electric or Nitro? If electric, I think the E-Revo Brushless edition or the Rustler VXL. If nitro, the 4-tec seems to be really fast.
