RE: NIMH receiver batteries charge with NICD charger that comes with TX/RX?
Not only will the wall wart do an acceptable job, your batteries will last lots longer if that is all you ever use to charge them. Sure a fast charger is faster (why else call it a fast charger?) but is harder on your batteries than the wall wart is. With the wall wart, if you have the time, you have the best of things. And yes, it will work for both 4 and 5 cell NiCad or NiMh.
