Well, it ran perfect for a half pack then the glue failed. The kevlar wrap protected the windings, so no damage done.

So, does anybody know of a glue stronger then JB Weld? It will take a couple of weeks to get a new motor from the states, plus nobody has a 1515/2d in stock, so I would like to try and fix the Feigao. I was going to wait until the Castle Neu's are out, but that won't be for a while yet.
RCM has the 1515/2.5d in stock, how will it work on 4s? The speed calculator says that an 18 tooth pinion will give me the same speed, but the motor rpm is only 23100, which seems really low. I would like to stay with 4s for now, as I just bought some new batteries.
Thanks
