Next time, compare the flight pack to teh cheap 4 ch. complete radio package.

Futaba flight pack is $169 up here (and you still need to buy the crystal)
Futaba 4 ch sky sport is $189. You get teh chrystal, and you get a charger, servo tray, and an extra Tx. Which means you get an extra Tx battery pack, should the original fail (or you are into electrics..) And, teh extra Tx can be used as a buddy box, or plugged in to the PC for the flight sim (witheth proper cable of course..) adn spare parts shoudl the original giombals fail..

You figure out the marketing...
