i know i should only run 5s, but 6s is just so tempting. i have read over at rcz of one person running 6s without any problems. also i called quark and they said that if i have any problems that i could send my 125b in for repair/replacement. BTW i have never overheated my 125b or had any other sort of problems with it, so i think i'm good to go on 6s..................

also, in mikes quark durability test ( http://www.rc-monster.com/forum/show...urability+test ) he ran 6s 2300mah a123 cells.................... check post #6
