Exactly so running the larger pinion may not overload the ESC, but having a higher gear ratio (smaller pinion) could cause the voltage to rise above a point that could damage the ESC during braking. If you were doing a bunch of speed runs and hard on the brakes I think you could generate enough to damage it. The TVS could short and then open as they often (when they fail) do then you have little protection. I haven't tried to see how much a motor will generate at such a low KV (My lowest is 3300) but it's probably pretty high at the speed you would be braking from. Then once the componets aredamaged they could typically self destruct upon application of power.
Of course this is all speculation on my part.
