designed for standard-sized servos.  
We recommend the following receiver power supply: two GRAUPNER 5N-5000 
NiMH packs, Order No.98903.5, which should be maintained carefully before and 
after each flying session. Please note that batteries of this type do not reach full 
capacity until they have been charged and discharged (cycled) several times. 
 
 
 
 
 

 

 
 
 
 
You will need four suppressor filters, Order No. 1040, or a folding ferrite ring, Order 
No. 98516.1 and four extension leads, Order No. 3935.18, in order to connect the 
two aileron servos and two landing flap servos to the receiver, i.e. these leads are 
plugged into the receiver permanently. 
The following servo leads are required: one extension lead, Order No. 3935.75, for 
each aileron servo, one extension lead, Order No. 3935.32 for each landing flap 
servo, and one extension lead, Order No. 3935.75, for each elevator servo. 
The receiver and receiver batteries should be packed in soft foam for shock 
protection. 
The model is suitable for standard-sized servos with an output torque of around 50 
Ncm.
