Hello, I recently bought a new castle creations mamba monster 2 combo with a sensored 1515 motor. I run in a lot of sand so I took it apart to clean it and put in some nice orange seal Boca bearings sense I have run them in the past and they are great. When I took it apart the shaft size bearing and the non shaft side are two different size bearings. No big deal I called Boca and they fixed me right up with the right one. (The sealed cap side was smaller then the shaft side) The issue is when I called castle creations they said none of their motors have two different sizes and I probably got a knock off. My issue is I bought it right from my LHS and it was sealed with a castle sticker pack and the coupon code you get for the link when you buy a combo. Has anyone here changed their bearings in a sensored 1515 2200kv motor from castle? If so please let me know if they were the same size cause this is making no sense. And if my LHS is seeking fake castle products I think I need to get this straightened out. Thank you for your time and I hope everyone can see the picture.
