Well, binding in the drive-line is the same for your BL combo as too tall a gearing.
If it's enough to fry an ESC is another question. Could well be, though.

I once got a pebble into the chain-drive of my TF, pushed the throttle only for a second, and the ESC thermaled. Afterwards BK told me I had a 130 amp peak on it. (seemed strange to me, was only running a 9L on 14 cells)
