Flight pack vs radio sysytem
I'm confused. I have a Futaba 6exas radio. I have several kits waiting to be built. But I have a question regarding the cost of a new radio system vs a flight pack. I've looked on the web and talked with the local LHS on flight packs. It seems that flight packs run just a few dollars less than a radio system. But some flight packs don't furnish the battery pack, and some furnish the battery pack, but you still have to purchase the crystal either way. I understand the crystal purchase. It seems the only advantage to buying a flight pack is to reduce the number of TX's you would have to store, and less confusion as to which TX would go with what plane. I'm new to this but would like to hear from all of you on your preferences.
Thanks
