I have an M18 that I'm trying to wring a little more speed out of... It's fitted with a Tamiya sherman DMD and MF currently. I know people that know people that have run them on 12v in 1/6 scale vehicles, but what I don't know is whether the extra voltage gets passed on to the things that the 1/6 scale guys might not have used - i.e. the flash, TBU and IR LED. Has anybody experimented with this successfully, or should I be nervous about things going pop?!?

(Secret option B might be to try El-Mod - I don't have a problem with blowing up a $15 HL flash unit in the name of science, a $50 Tamiya flash unit is a different proposition...)

Should probably add: I'm thinking of 7 cell 8.4V or 8 cell 9.6V NiMH packs, no more than that.
