I don't think you'd see more than about HS3000, since under load, there will be about 3.8v per cell - but it's still pretty hot gearing.
Bear in mind that Align warn against any more than HS2650 for the regular 500, and maybe it's the tail rotor that's the limiting factor. HS3000 would represent an overload of approximately 30%.
