Interesting read. Also poses another question. I am still using my old 72mhz Futaba 8ua radio.
I just purchased the LiFe receiver batteries and the Hitec X4 charger to support them (and any future charging needs I may have) .
That said, Should I use a reg ? The LHS says I am fine, but they may be thinking about the Spectrum Radio's/Receivers they carry.
No problem with receivers but the higher the volatge the more speed/power is produced by the servo which also increases heat,
wear and tear which shorten the life of the servo. Sure, a fully charged 5 cell NiMH/NiCD battery is at same voltage but not for long.
Majority of known users fit a good UBEC (aka SBEC or Switchmode Regulator fixed at 5.5v to best of all results.
4A BEC is minimum for sports Nitro/GP models but when weight is not a problem, 10A is best overall.
