  1. its a 3900kv motor which is different that what Castle offers. Also, it can only handle 2s lipos. Looks also to be smaller

  2. no point in getting all worked up over something you cant control. chill out man.

  3. it’s not a clone it is made by castle.and bet it doesn’t come with the fan that the castle comes with, so it lowers the over all cost .


    1. OEM is found in full-size auto too. Why is it costing less a bad thing?

      1. Why? Cuz it sucks when you spend $$$ for R&D and someone clones it for 1/4th your R&D and sells it for half using communist work slave camp peasants and your sales drop below projections. You’d like to innovate something else for the industry and try something else but you give up on that idea since you fear it will just be cloned again so why try. Then as sales continue to drop with your new clone competitor you try laying off staff but your unionized electricians wont let you, so you consider cutting everyones pay instead and the Union boss thugs rough you up in the parking lot. All the while your politically demonized for being rich by those who did less than you in life and being taxed to pay for huge social programs, again by the same group of people. Thats why?

        Welcome to the industrialization of America.

  5. So how many companies are actually using Castle’s esc’s now?
