If you're radio will handle a 5 cell nih pack, the 2 cell 2300 Mah A123 battery is a direct drop in, no regulator is required.
I'll do some research to learn whether or not my receiver (Futaba) can handle a 5 cell nih pack. After looking at the web link you provided, I don't think the batteries I linked are the same at all. The A123 batteries have a much higher output capability.
