ihave some old electric rc cars about and was wondering if i could use the 7.2v battery sticks in my st2 for the power to the servos and would i gain anything by using them or would it end up burning anything out hope you can help thanks

you won't gain anything other than burnt out servo's and receiver..... besides, what were you trying to gain... the batteries are very heavy and the speed gains if any, won't outweigh the weight... Just get a 6 volt hump pack.......

yeah i thought that would be the case thanks for your reply
