+1 on the Tactic; I have both the Tactic and the DX6i and IMHO the Tactic does every thing the 6i does and is easier to program at a lower price.

It appears that you have a 5 cell battery. A safe way to charge it is to use one of the old wall warts that come with many of the transmitters/receiver packages. They usually put out about 50ma or...

I'll second the recommendation to use Eneloops. They work very well and are about as good as LiPo's for holding a charge yet very easy and safe to charge in place.
