what Tx are you using Eneloops in?.........i thought you had a 14MZ............
You were editing to add this while I was typing my last post. Allow me to answer.
I own 6 radios right now. A Futaba 3PM, Futaba 4PK, Futaba 6EX-FASST, Futaba 9ZAP, JR 9303, and the Futaba 14MZ you noted.
I use the Eneloops in the 3PM, 6EX, 9ZAP, and 9303. I have changed my 4PK over to the Hyperion LiFePO4 pack and it is working very well. In addition I have 6 5-cell Eneloop RX packs that I have used in both boats and aircraft.
As I noted, I now use the Hyperion LiFePO4 packs in all my planes. I no longer use conventional NiMH packs in any plane, boat, or transmitter. But that is only because of not liking the self discharge that is typical of them.
