Heard a roumour today that the brca are concidering making 10th off road 5 cell and that 7.4 v lipos wont be allowed ( unless of course you devise some kind of restrictor circuit ?)
aparently it was in radio race car although I haven seen it myself.
getting a bit miffed though as I've got one of the brca aproved lipos and now I may not be able to use it at even club level if the decisaion is made to run 5 cell.
