all you need to get is a flight pack for each plane your using, a flight pack has battery, receiver,and 4 servos.
I have to say looking on the Tower site, that a futaba flight pack will cost 112.99 with out the crystal (which cost 12.99), so I am simply going to buy the 4 channel futaba radio that has the same receiver that came with my 6 channel futaba, includes the crystal and only costs 119.99, and it includes a spare charger so I can charge the 2 batteries at the same time, and I can use the transmitter battery as a spare for my 6 channel transmitter, I can not see the point of a flight pack when it cost more to get the same personally, although this is a bit OT
