Flight packsFlight packs  since your Futaba 4EX transmitter holds memories for up to four models, there is no need to purchase a 
complete radio system (including the transmitter) for every model you fly. Available separately, Futaba Flight Packs contain a 
receiver, servos, switch, battery and all servo mounting hardware. Consult your dealer or the Futaba Service Center for 
specific contents and order numbers. 
Receiver crystals:Receiver crystals:
The receiver frequency may be changed as long as it remains within the “low” and “high” band frequency range. If your 
receiver is on any channel from 11 through 35, it is a “low band” receiver and the frequency may be changed to any other 
channel from 11 through 35 without having to perform any other service. Simply purchase a crystal on the desired channel, 
then replace the existing crystal in your receiver with the new one. If your receiver is on any channel from 36 through 60, it is 
a 
“high band” receiver and the frequency may be changed to any other channel from 36 through 60. To order a receiver 
crystal, replace the 
“**” in the order numbers below with the required channel number. (To order a receiver crystal on channel 
30, order FUTL5730.)
