I appreciate all the responses, especially Kevins. That's what I was looking for...

I've already got the pack and it's a 4.8 volt. I'm not really concerned with how a 6 volt pack does...

I've heard that a Nimh can't handle the current draw that a nicad of the same capacity and voltage can...I don't want to have any problems throwing all the sticks around. Looks I shouldn't worry about it...

I've got a charger that can handle nimh, so that should not be a problem... Can I expect about twice as much flight time with this pack?

Chuck, I've got 2.5 inch foam wheels that are about half the weight of the foamies that Morris gives you. Now my Wooly Mammoth skins, those are great for the winter.

Thanks for the link Ulf, I'll think I'll have to order a transmitter battery now...
