Just two days ago I was in the local hobby shop when a friend and fellow modeler brought in a battery holder for his transmitter. He was complaining that the replacable cells (not soldered or welded ) had intermittent connections and the transmitter would go off without warning.

If you are interested in relaibility and put the cost of a possible crash above the cost of a welded nicad pack then the choice is clear. Do not continue to use a battery holder with replacable cells. There are reliable, plug-in repalcements for such battery holders and their unrelaiable performance.

Greetings,

Dito. Nothing like the increased reliability of a soldered pack.

Many, many moons ago when I just started RC gliders, I had a TX with the dry cells. I still remember with humor of slaping the Tx when I thought I was getting hit. Sometimes it worked, more often than not, it did'nt.

Good Luck,

Jared

A little counterpoint.
I've got a battery holder with 8 1600mAh NiMH AA cells for my Stylus, and all I did was wrap some fiber tape around everything to hold the cells in place, and I've flown it over a year without a single glitch. And I'm seriously hard on my TX (lives in my backpack, gets carried up and down mountains, and flops around in the car for a week at a time). I fly $60 foamies and $1000 crunchies with it alike.

What I love with the consumer NiMH AA cells is that they're cheap and improving in capacity seemingly every day. Mine have held up to a lot of abuse in terms of charging (I charge em at 1C often) but I'm still getting several hours of flying out of em on any given day on a single charge, and know I can replace the whole pack with new cells no matter where I am in the country.

soldering is the sure way to go but if you want there are products sold in the RV dealers that help to insure a good contact between the cells,its a kind of gel that is conductive
