Duane and others, I have been wondering what you guys think of redundancy where your flight pack batteries are concerned. I have seen so many horror stories on low voltage disasters that I'm inclined to consider a two battery pack/double switch arrangement for the Simla. Which brings me to the question 4.8 volt or 6.0 volt packs and atwhat amperage? I'll most likely be using my Futaba 10 CAG system with an R6008HS receiver and S3050 servos with a HydriMax 5 cell 6 volt 2000mah NiMH battery pack (or two?). Any input would be helpful and appreciated.
