Foamy,
Once again I hate to break this to you, but there is no NiMH+ batteries that I know of. I'm pretty sure that you are just falling for some slick sales pitch. If there were a "new" type of battery chemistry for NiMH's I'm pretty sure that we would have heard about it before you came along to educate us. But if you want to go ahead and believe what he is telling you that is definitely your prerogative. Charge you batteries and let them sit for six months and go flying with them. But if you do that please take one small piece of advice, take a trash bag along to bring the plane home in.

You'll find as you get older that salesmen will make a lot of "claims" as to how great their product is in order to sell it. But when people buy it and take it home they find that the actual performance isn't quite up to what the salesmen said it would be. This has been going on in this world for centuries now, and I doubt that salesmen will suddenly become "honest" anytime soon. There is a great Latin saying that comes into play here, Caveat Emptor. It means "buyer beware".
