so if you're only building
your Viper as a basic
wedge, now would be a
good time to use some
zip ties to do some wire
management. You want
to keep everything out of
At this time,
everything should be
ready for a test drive.
You want to plug in the
charge plug (which
doubles as the
mechanical kill switch)
before plugging in the
battery. Place it on
something to keep the
wheels off the ground.
You always want to have
the radio on before you turn your bot
on. You can now remove the charge
plug and the right stick on your radio
should drive the robot.
There is a nice troubleshooting
section in the back of the manual if it
isn't driving correctly, but if you're not
using the optional radio offered by
Finger Tech, you might have the mixing
done incorrectly so this will require
some further investigating.
Now you have an almost
complete driving little robot. The final
step is to screw on the armor; in this
case, Lexan. You'll want to use
threadlock on all the screws to make
sure they stay in tight during a fight,
but I'd also suggest
putting in all the screws
loosely before tightening
them down. This makes
sure you have the plates
all lined up correctly.
Make sure to drip the
threadlock into the
inserts instead of onto
the screws. This way, you
won’t get any on the
severely weakens Lexan!
You now have built
your Finger Tech Viper kit.
If you had any issues,
you can contact
Finger Tech at the email
address on the back of the manual, as
well as check out the links towards
the back of the manual.
Now that you have a complete
working combat robot, you're ready to
compete. That said, at this point it
only weighs around 11 oz, so with
many events running the Antweight
class (or 1 lb class), you can still add 5
oz of awesomeness to your new bot.
You can do this many ways, but
the easiest way will be one of the
Add-On kits Finger Tech offers. They
have both a Spinner Add-On for those
that want to spin to win, as well as a
Lifter Add-On to flip the opponent. I
opted to go with the Lifter Add-On
and found it to be as straightforward
to assemble as the base kit.
