The esc's have definately changed stock, but unfortunately they missed the boat big time in terms of keeping it a "stock" class. Now it has to run its course.... it will either just keep advancing and everyone will keep upgrading to the latest and greatest, or it will slowly start to die out as people either leave or go to mod where they dont have to upgrade there esc every 6 months. I think it will be the 2nd, it will die out and they will have to bring in new rules to bring down the cost of stock racing.

Just my 2c.
