I've ordered a 5v regulator to install with my A123 2S on-board battery to permit me to eliminate the ignition 4 cell pack. I know I need to carefully check range, etc.

I'm also using Spektrum 2.4, so anticipating no radio issues and plan to use existing ignition switch, cutoff, etc. just as is, just replacing the battery with the output lead of the regulator.

Anyone done this? Comments? Things to check?

(Ignitions that will be tested are the DL 50, and the CH on Brillelli engines)
