Hi I'm looking for help finding a product for my radio system. i have a 6v receiver and a HV servo. I want to find a step up regulator (or anything that can do this really, preferably variable)that i can put after my Receiver, and before my servo that can take 5 cell nimh in and output at 7.2 to 8.4 volts up to lets say roughly 3 amps. if anyone knows where i can find one or how i can make one please let me know. thanks in advance
