many times has this happened to you? You just
finished building your new pride and joy and
you are now installing your electronics. You
have placed them in the best location possible
to get that proper front to rear and left
right balance and now you hook everything
into the receiver and you end up with a rats
nest of wires, ugh!!!
there are three options. Option one is to
open up the cases and de-solder the wires
to the board, shorten them, strip the wire,
solder the wire to the board and hope it still
works. Option two is to coil the wire around
a circular object. Option three is to cut
the wire to the proper length, strip the wire,
and install a new connector. With the help
of one of my new tools, I am going to walk
you through option number three.
is only asking for problems.
found this bad boys
of new tools here is mine, the Pin Full Cycle
Wire Crimping Tool which I purchased on E-bay.
I was able to pick it up, auction bidding, for
under $15.00 shipped. The last time I checked,
you could pick up your own version for under
$20.00. What makes this so unique compared to
others that do the same job is this one has
a ratchet mechanism. Why is that so important?
Well, with the ratchet I can close the jaws
just enough to insert the pin and it will stay
so now that you have picked up the tool you
also need the servo cable ends and crimp connectors.
A quick Google search took me to two options
sold by TQ Racing. They offer two choices, one
with JR connector ends and another with Futaba
connector ends. I found that the JR connectors
will work with Futaba receivers but it will
take a little work to get the Futaba?s
to work when it calls for a JR connector.
now we have the crimping tool and cable ends
and crimp connectors. All that is left now is
some wire cutters, marker, and wire strippers
or sharp finger nails will work.
the electronics installed I want to straighten
out the wire so there is no coil left in it.
With the wire now straight pay attention to
the color of the wire and the position of the
connector because you need to reassemble it
in this order. I will now mimic how the wire
will reach the receiver. Now don?t get
ahead of me and cut the wire just yet. You have
to take into consideration the connector itself.
Ideally, you will want the connector to enter
the receiver straight up and down in my case.
You don?t want the connector to enter the
receiver at an angle because you risk damage
to the pins, which is an expensive mistake if
you break one off.
that I know the length that I need, I will simulate
installing the plug into the receiver. I do
this because I don?t want to cut the wire
to short and end up ruining something when plugging
it into the receiver. With my simulation now
done I should have a pretty good idea as to
where I can finally make my cut. With the wire
cut now separate the three wires using the piece
you just cut off as the guide. If I were to
guess I would say ½ an inch from the
tip but use the cut off wire as the guide.
strip the wire but before I do that pull out
the crimp connectors and break them one off
of the tree. Carefully lay the wire inside the
channel of the crimp connector. You will be
able to tell how far it should go into the connector
by looking at the pieces that will overlap/secure
the wire in place. There are two sections so
look closely. With the wire laid in position
mark where you have to strip the wire with your
marker and mark the wire at the end of the connector.
Do this for all three wires. This mark will
identify how far you have to stick the wire
into the connector before you crimp it all together.
Now go ahead and strip the wire and twist it
to help keep it together.
time, finally. Grab the crimping tool and start
to close it to engage the ratchet mechanism.
Close it just enough so that you can insert
the crimp connector and have it stay in position.
To have the tool hold it into position insert
the end into the side of the tool that says
24-28 on it.
identify how far to strip the insulation and
will insert the wire into the other side.
end that is now exposed on the 24-28 side is where
you will insert the wire up to the mark you made
on it. With the wire inserted, slowly close the
tool but don?t clamp it tight or you will
risk deforming the crimp connector, of course
I am speaking from experience. Now repeat this
process for the remaining two wires.
of the actual connector is pretty self explanatory.
Refer to your notes you took to the order that
the connector pins will be installed into the
connector. If you forgot this step don?t
worry. Take a look at the wire you cut off earlier
and follow that layout. It is important that
you reassemble it the same way because each
wire serves a unique purpose.
have now repeated the same steps for my speed
control that I did for my servo. As you can
see in the picture, I no longer have that
ugly looking rats nest. I now have a respectable
looking wire job. That nest was just asking
for radio interference to happen at the most
unfortunate time, like at the end of the straight
you set out on this task take your time and
be patient. Make sure you have the proper
tools available to do this and don?t
try and make something do the job it wasn?t
supposed to do. You are dealing with some
expensive pieces of equipment, in some situations
and I don?t want you to destroy them.
I have been involved in R/C since the early 90?'s.
I have participated in dirt oval, carpet and paved
oval, on-road and off-road racing. I have found ideas
that work and ideas that seem to be good on paper
but fail for one reason or another. I have been involved
in the rules decision process and tech inspection
for one of the largest indoor on-road only events
held in the U.S.
