Lots of people have been doing this for a while. The last two helis I build I used the A123s w/ the AR7100. The nice thing about this setup is that you won't need a regulator if you have servos that are rated for a 5cell nicd setup, as a fully charged A123 pack is about the same voltage as a fully charged 5cell nicd pack.

Works great and no worrying about failed regulators.

Thanks. Is the voltage drop for this kind of cell very fast and drastic?

Been doing it for well over 9 months! All Spktrum rx. Voltage drop is fast near end of discharge, very flat 6.6-6.5 till that point. Can be recharged at 4 amps with Cell Pro charger. Don't know about other charger capabilities. I build my own packs an charge on an individual cell basis. Although that probably is not necessary.
