RE: Chargers
I don't currently use NiCads. I went to NiHM a few years back for all my Rx/Tx battery packs.
I do most of my receiver pack charging with a large power-strip plugged into an appliance timer. Then I plug wall-warts into the power strip (mine's a heavy-duty 12-outlet strip from inside a server tower). I set them to charge an hour a day so I can go flying any chance I get. If I plan ahead I charge everything overnight.
For field recharging or to cycle NiMH packs I have a Triton Jr (I keep the the car) and a Triton 2 EQ (12v & 120v) that I like. Also a DuraMax ICE that is supposed to be for R/C cars but it dosn't know what the battery goes into. The ICE was on sale and works well for NiMH charging and cycling.
It does a LOT more than the Jr. for only $10 more cost even at full price.
I'm just getting into electric flight and the Triton 2 EQ seems to do all I need. But I was surprised at all the "accessories" needed to do LiPo packs. Balancers, adapters, banana jack to all the various connectors. The peripherals cost as much as the charger!
