I have an older version DA 32 and the ignition calls for 4.8 ~ 6v. I have a 5 Cell 6V / 6 Volt 1600mAh NiMH Hump Receiver Battery Pack that I'd like to use if it'll work. The servos I have call for 4.8 volts. Can I use it to power the ignition and servos by stepping it down to that voltage? If so, how would I do that? Any help will be greatly appreciated.
