If you think you are sticking at 4S and with a buggy a MM / UBEC and extra Cap will work fine... However new this will set you back 115+20+10=145 a MMM is due (fingers x'd) EOM and should be 180-200ish and you won't need the BEC/Cap...
The Duo's pretty pricey maybe easier just to get a smaller charger - ATB
Not a problem on the price of the MM but is there any info on putting the extra cap on it?? also If I recall isnt there someone on here that will mod them for you??
THanks!
Also do you think I am better off gettin the Hyperion EOS 610i NET charger. I really just want something that will be able to charge as quickly a s possible
