Note:
Be careful not to break the antenna wire on the new
ASF 2.4GHz PCB!
1) Servo Potentiometer wires: These
are the hardest to do, since they are so delicate. The
ASF 2.4GHz PCB uses a 3-wire Servo Potentiometer setup
instead of the old 2-wire. Carefully disassemble the
servo assembly and lift the servo gear rack out of the
chassis to get access to the Servo Potentiometer. You
will find 3 prongs on the Servo Potentiometer and that
one of the wires (usually orange) is soldered to the
center prong as well as one side. Carefully cut the
wire connected to the center prong and remove the excess
with a soldering iron. Add a new wire running to the
center prong of the Servo Potentiometer (I recycled
a white wire removed from the Power Switch in Step 3).
You should now have 3 individual wires running to each
prong on the Servo Potentiometer.
These wires are designed to run in slots cut into the
servo gear rack so that they don't get pinched when
the servo assembly top cover is installed. Since we
are adding another wire, you should cut these slots
a little deeper to allow for room.
Carefully solder the 3 Servo Potentiometer wires to
the area at the front right of the ASF 2.4GHz PCB. The
green wire goes in front followed by the new white wire
and then the orange wire.
2) Servo Motor wires: Again, carefully
solder these delicate wires to the area at the front
right of the ASF 2.4GHz PCB. The red wire goes toward
the rear and the black wire goes directly in front of
it.
When you are done the Servo Potentiometer and Motor
wires should be in this order: front <= green, white,
orange, black, red => rear
3) Power Switch wires: You will have
to lengthen the Power Switch wires by about 1/2"
to reach their new location on the ASF 2.4GHz PCB. Carefully
remove the Power Switch from the chassis, cut and strip
the longer wires and resolder them. Remember to solder
to the same tabs or else the Power Switch will work
backwards. Solder the new longer wires to the area toward
the left rear of the PCB right in front of the Battery
wires. The new longer wires that I used in this picture
are black as opposed to the old white wires. I recycled
one of the old white wires for use with the Servo Potentiometer
in Step 1.
The Power Switch wires use the 2 front solder pads
in this area and their order doesn't matter. The area
where you solder the Battery+ wire is shared with one
of the Power Switch wires, so don't worry if they end
up touching.
When you are done soldering in the Power Switch wires,
you can reassemble the servo by carefully installing
the servo gear rack and top cover. Be careful not to
pinch any wires during this process.
4) Battery wires: I like to clean
up my battery wiring and hardwire directly from the
tabs to the PCB instead of using the screw terminals
on the chassis. The Battery- wire is toward the rear
of the board and the Battery+ wire is directly in front
of it. The area where you solder the Battery+ wire is
shared with one of the Power Switch wires, so don't
worry if they end up touching. Just make sure that the
Battery+ and Battery- wires are separate and that the
Power Switch wires are separate from each other.
5) Motor wires: These are the easiest
to do. You will have to flip them compared to the old
PCB, since on the new ASF 2.4GHz PCB, Motor+ is on the
left side of the board and Motor- is on the right.
Tada! You are done with the wiring portion of this
upgrade!
