Really?? Unless HK are bringing the products into the UK using black speedboats in the middle of the night and storing them in hidden caves I don't think anybody has anything to worry about

Im pretty sure duty is paid if buying from the UK warehouse anyway
On a serious note, the focus of the BRCA needs to be more on how people use their LIPOs rather than dictating which ones people can/can't use at regionals/nationals.
Personally, Im a club racer and haven't bothered with reigionals for some time. If I did choose to go to a regional I would hate to be turned away because my Turnigy/Zippy lipos (which are excellent BTW) weren't on some list.
I did scruntineering for 1 round a few years ago and some kid turned up with an EZrun sensorless motor - not on the BRCA list but I just turned a blind eye and let him race.
I've only witnessed 2 LIPO fires in the past, in both cases the LIPOs were on the BRCA list but they still went up because of mis-use and mechanical failure.
My club has strict rules on using LIPOs:
1) Max 1C charge
2) No discharging using the charger
3) Must be charged in safe container (sack, aluminium box etc)
4) Hard-cased varieties only
Although it is sometimes hard to do this, but we do try and enforce these rules every week.
There may be something similar in the BRCA rules but I would much rather "the list" would be relaced with something to enforce the above rules.
