NEED HELP :( F18C Ducted 70mm jet

Ok so I got a new jet and have flow it for a while. I recently played around with the esc settings and set the engine to CCW just to see if it worked, upon setting it back I noticed a nasty bearing like noise.

Does anyone have any idea where I can get a new brushless engine for it?
2836 Brushless Motor

Also, a bit of other information. I'm also getting a new battery because one of the cells on my 4cell pack is dead. When I tried it, it was hooked up to this half/working battery. Here is what the included speed control is

Just to be clear, it is a 14.8 volt 4S 18C battery pack that is used

Check the thread in the foamy forum on this jet - lots of info, and different set-ups.

I have a 68mm Haoye fan and a Walkera 380M in mine. The fan cost about $10.00 and the motor was $35.00. The Walkera motor would probably fit into the stock fan.

Also, Hobby City has all kinds of different 28mm inrunners for not a lot of $$.

Re: the battery - what capacity is it? If it's a typical 2100-2200 4S, and it's only 18C, you'll be lucky to get more than a few flights from it.

Most 28mm inrunners in the 3000-4000 KV range in typical 68-70mm fans draw 40-50 amps, so even a 25C 2200 pack will be working very hard, and won't last too long.
