Live & learn
Trouble with savage Flux guys is that they are mainly noobs who've just spent ~$600 on an RTR BL MT; no prior experience usually of how to care for these large scale, heavy MTs and 1/8 BL systems, and no realy knowledge of suitable lipos. I've seen the rather small SMCs recommended by HPI themselves since they fit nicely, and are a well known 'American' brand... its scary stuff.
If you went over to HongKong or South Korea maybe, Im sure you'd see the hobbycity lipos being promoted for use in all manner of RCs....
