If I was you I would consider going a little bit bigger than the 600mAh. I am new to this as well, but I have started to use 1100mAh in 4.8v for the plane and I can get more flights per charge than I was with the 600mAh. For example when I used the 600Mah I would take three full flights and then stop or go to another plane, you could probably get more than three flights but I did not want to chance it. Now with the 1100mAh packs I am taking six flights per charge and I am still showing I have juice for another flight or more.

The same to the TX or 9.6mAh battery. Just a few days ago I made 14 flights using the same TX and I was still showing plenty I had plenty of juice to keep going. Look around and you will find the bigger nAm packs are not really that much more in cost, but they will take a little longer to fully charge than the smaller nAm packs and your standered wall charger will charge them.
