The esc can handle 6s yeah, but not in the flux- its too heavy and running 6s will cause too much current draw with that motor basically, thats why its limited to 4s in the specs. It may well work though given the old MM setups many people used to run, but it would be a warrenty void if nothing else, and HPI would be the ones to handle any claims- they may not have the same cheap non-warrenty replacement scheme in place..
