1. Connect the transmitter charging jack and airborne Ni-Cd batteries to the 
transmitter and receiver connectors of the charger. 
2. Plug the charger into a wall socket. 
3. Check that the charger LED lights.  The batteries should be left on charge for 
about 15 hours when recharging the standard NR-4J and NT8S600B Ni-Cd batteries.   
 
 
   
    Only charge the batteries with the charger supplied with your system.  The 
use of a fast charger may damage the batteries by overheating and dramatically 
reduce their lifetime. 
    You should fully discharge your system’s batteries periodically to prevent a 
condition called “memory.”      For example, if you only make two flights each 
session, or you regularly use only a small amount of the batteries’ capacity, the 
memory effect can reduce the actual capacity even if the battery is fully charged. You 
can cycle your batteries with a commercial cycling unit, or by leaving the system on 
and exercising the servos by moving the transmitter sticks.    Cycling should be done 
every four to eight weeks, even during the winter or periods of long storage.    Keep 
track of the batteries’ capacity during cycling; if there is a noticeable change, you 
may need to replace the batteries. 
 
You may change the length of the control sticks to 
make your transmitter more comfortable to hold and 
operate.   To lengthen or shorten your transmitter’s 
sticks, first unlock the stick tip by holding locking 
piece B and turning stick tip A counterclockwise.  
Next, move the locking piece B up or down (to lengthen or shorten).  When the 
length feels comfortable, lock the position by turning locking piece B 
counterclockwise.
