Range Checking your Radio System
After you have finished the final assembly, it is
time to range check the radio system within the
Bf-109G BNF.
Prior to Each Flying Session
• Turn on the transmitter prior to plugging in the flight
battery. With the airplane on the ground and motor
running, you should walk away approximately 100
feet and still have full control of all functions while
following the specific range test feature of your
DSM2 transmitter. If this is not the case, do not
fly! Call the Horizon Support Team at
1-877-504-0233.
• Always make sure that all controls are functioning per
the transmitter input that you are giving. This includes
ailerons, rudder, elevator and throttle.
• Always make sure you have fully charged the
transmitter batteries.
• Always remove the flight battery from the
airplane when you are done flying, or when you
are on the way to the flying field.
Control Direction Test
1. Move the elevator stick on the transmitter
forward and aft to check elevator pitch control.
When the stick is pushed forward, the elevator should
move down.
2. When the elevator stick is moved aft the elevator
should move up.
3. Move the aileron stick left and right to check aileron
roll control. When the stick is pushed to the left,
the left aileron should move up and the right aileron
should move down.
4. With the aileron stick pushed right, the right
aileron should move up and the left aileron should
move down.
5. Move the rudder stick left and right to check yaw
control. When the stick is pushed to the right the
rudder should also move to the right (if viewed from
behind the airplane).
6. With the rudder stick pushed to the left, the
rudder should move to the left (if viewed from behind
the airplane).
If at any time during the test the controls respond in
the opposite direction, it may be necessary to reverse/
change the direction of operation of the flight controls.
Follow your transmitter instructions to change the
direction of the various flight controls.
