Yes, the low self discharge NiMh's such as the Eneloops are IMHO much better than using LiPo in your transmitter as they hold a charge as well as LiPo's do yet you can charge them in place and with the simple wall wart chargers with no danger of fire or smoke and no damage if you forget and leave them on charge to long (assuming you are using the wall warts with a charge rate of 0.1C or less). Also more economical.
