futaba 4pl question
#3

I've used these rechargable AA's in my 4PL for a while now and they work great for half the price. Just make sure if you go that route, you buy the higher quality ones like what I linked to and not the cheap grocery-store ones that won't hold the voltage high enough long enough.

Regular AAs will last a long time before they need replacing, I'd just stick with those if you don't want to fork over the money for a LiFe. AA NiCds are nice too if you can find a good deal on them. I use AA NiCds in all my TV remotes, usually have to recharge them about once every 3 months or so.
