RE: A123 Power Setup
ricomari ..to answer your question if it is in re guards to the a123 batts system no regs are necessary in any part of the system at all
I use a standard futaba 3004 servo on my throttle and a manual choke with a ignition kill switch [link=http://www.troybuiltmodels.com/items/WRCIBEF.html]from TBM wike r/c [/link]
and for my switches i use [link=http://www.troybuiltmodels.com/items/MPI3470.html]MPI HD switches [/link] one for rx the other for my ignition . running a single battery for both ! A123 2300 mah
