I like flight packs because I use a 6XAS computer radio. Servo City sells custom Hitec Flight packs. 2 to 5 servos - your choice of type, choice of battery NiCad or NiMh and size plus a choice of different Hitec receivers. I'm buying a pack that has 3-425, 2-475, Supreme 7 channel receiver with crystal and a 1000 NiCad battery pack for 135.00. Good deal.
