Adequate? I can't answer that fully. As long as you are not exceeding the lowest maximum rated component in the chain...you should be fine. I haven't dealt with high voltage gear and lights, then trying to run everything off the main battery.

Did nothing RC related today, except for researching specs and tweeking Evader ST's & SC10's setup. After reading about everyone's huge torque-ish servos, I sit here, and think I need to get another CC BEC for the Yeti. The time will come soon enough for when I want to increase more servo brute force.
