After I posted the recommendation of LiFe, I realized I should have mentioned my great respect for John Buckner.

What he says in his recent post is true.
` ` ` Need LiFe capable Charger.
` ` ` I keep the Balancing leads close to the wing opening and use an extension on the charger, easily and inexpensively available from the same source as the FrSky receivers.
` ` ` NiMH is not old tech.

One thing he did not mention is that, if a LiFe Battery is discharged beyond a certain voltage, the LiFe compatible charger will not charge it. (LiPos have this same trait.) Let that happen a couple of times and you have a supply of leads to use to extend the battery lead. Serendipitous???

So, with all that, why in the world did I recommend them?
1) They have worked very well for us at our club and for clubs in the area, even without the extra mods mentioned above. Guys keep them easily removed to charge or use the inexpensive extension on the charger.
2) The same battery works in our chargers, purchased in the last 4 years. (Not in the 7C)
3) When I cycled all my NiMH packs this winter, they ALL failed!!!! Not the old NiCds, just the NiMHs.

I do have a pair of Futaba 6EX transmitters, which are used for buddy-boxing. NiCds work just fine for both Tx and Rx.
