I was checking the prices of single cell batteries and they are much cheaper than the ones in packs. I got interested in these two:

Sanyo NC4AA Hi-Capacity NiCd (4)

Venom 2400mAh AA Rechargeable Battery (4)

My plane uses 4 Futaba S3003 servos and my radio is a Futaba T4YBF (similar to the 4YF). My charger is a Piranha digital peak charger. I was wondering:

1 - Can I use these batteries in a 4 or 8 cell battery case on the plane the same way I use the packs?
2 - Can I charge them in the case, or do I have to charge each cell separately?
3 - Can I fast charge at C amps (after forming at C/10 of course)?
4 - Will the NiMH deliver enough amps or should I get the NiCd?

Here's my answer:

NEVER, EVER, NEVER, EVER, EVER, EVER even consider using a battery box that the individual cells just sit in under spring tension.

There's at least 16 places (on an 8 cell unit) that can have a failure due to vibration or corrosion.

Solder the individual cells together, using tabbed cells, join them into a pack using hot glue and be done with it.

Your mileage may vary..

acerola,
Just another post to agree with what Dick wrote. He is absolutely correct. Please don't do it - use a pack. Vibration will cause you grief and this includes the transmitter too.
