Wow! Great job on the write up. :-D I have been thinking about doing this with Tamiya Plasma Dash motors. How many amps are you pulling? Also what are the ranges? How many C is that battery rated for?
What is the charge time for TrustFires? Can I blast them with a 3-5c charge on a RC charger? I am a little impatient on battery charge times. It's like watching paint dry.
So what if I am using a Rayven or Hail-Fire? Can I tell from noise? Should I just change out batteries as soon as I hear or feel a range loss or noise reduction? Or is there a certain point where I should change them in the discharge cycle?
