Assuming it's just one vxl system, it will struggle - overheating big-style, unless geared to the moon (in which case it'll be tediously slow). I am told that it is possible to run e-maxxes with twin vxl systems if both are set up correctly. Generally, I'd steer clear though: if you want a brushless monster get a system that was designed to handle the weight of big trucks i.e. MMM.
