In my club, it is legal to run at 8.5volts ! I only pointed out that I ran my M03 at 8.4volts because my charger can't go beyond that. When I get my new charger(capable to charge up to 8.48volts), I am sure I will be able to match and surpass my buddy's 14.5sec fastlap M05..... Nowhere did I make any statements about people cheating by running with overvoltaged lipos ! The poster that keeps bringing that up should stop it ! After Hurricane Sandy, it is not time to pick on people on Rctech..... Ok...pal.....
