Default LiFe = A123? What charger should I use?

I'm looking to get into 40ish sized electric aircraft by this coming spring/summer. A few years ago I had a 50 sized electric heli I powered with a Dewalt A123 10S2P and a 14S1P pack. I used a bench power supply to charge them. The 10S2P setup provided great sport flying and the 14S1P setup provided insane 3D with an incredible turbine engine like sound.

This setup was amazing. 15 - 20 minute charge times from completely empty. I want something like this for airplanes now. I'm guessing that I'll be using a 4S - 6S pack. What kind of charger should I look at to charge them in under 30 minutes? 12 volt would be preferred, but I could setup an inverter for the car if needed.

I've been told at the field that I should use hobbyking when looking for any electric setup.

RS2K, I'm suprised to see that you never got a answer to your question on Dec of last year.
I can't advise you either but I'm wondering which way you went.
What ESC do you use & what are you flying now.
I also have tried Electric for years but never did go the Debult route.I'm trying to use the
Ternergy packs & having problems w/the chargers.
