Even tho the voltage cutoff is 3.5 volts JR wants you to stay above 4.8 as a minimum! If this was my large scale P-47 I would never even consider using 4.8 volt battery packs in a 2.4 GHz system! You are leaving yourself with practically no safety cushion. Look at all of the high torque servos you are running. Even in my smaller planes I use 6 volt battery packs for very real safety reasons. BTW, the receiver can handle the servos easily, it's the batteries that you are going to use that are the weak link.
Thanks a lot for your considerations, so do you thinks use two LiFe 2100 mah 6.6Volts is a good option?
