I'm getting ready to start a 33% TTOC Yak with SF PE Sport(I think), dual 2600mah Li Ion/switches& regulators. I'm still not sure how much current the 8 7955TG's will draw, even though Hitec says 2 amps each. If my set-up only has 8 amps total battery capacity(4 amps each battery)wont I be seeing large voltage drops? At 2 amps each, thats 16 amps, more than the batteries could sustain. Yet, this same set-up has worked for a friends 35% planes?? There is something I'm missing here, I can only assume that 2 A rating is assuming very heavy loading(large surfaces & speed)??
Why not skip the li-ions and regulators and go with a A123 battery?
For my 35% I am building I am going with all of the servos plugged directly into an AR9100 and two batteries plugged directly into the receiver. I think once you start needing to Y multiple, high current servo then a power expander becomes more viable. Given enough ports on the receiver however you could Y the signal portion of the servo leads.
