Yeah i know about the charging. I've gotta couple 300 NiMh packs for my parkflyers. I use the Airtronics wall charger on a timer for those as I do not yet have that Dymond charger that does 1-12 cells. I've only used nicds for reciever packs and have always used my buddies Sirius charger at the field if they run low. I'm thinking the 1700 NiCds would be better because you can overcharge them and they will take it. Not that I ever do but I know the NiCds will last for awhile.
