This
idea and mod came from Canadian-MGT on the Monster GT forum. You will
love this mod, if you decide to do it. I did it on mine and am using two
Airtronics 94358 servos, for a combined total of 400oz of torque. Thanks for
this mod, Canadian-MGT!
http://www.atomic-racing.50megs.com/page5.html , there's a link to a
page created by Canadian-MGT, where he explains the mod in more detail than
you will find on this page. I suggest you read through both pages (his and
mine) before starting on this project.
This is a great mod and it adds a little weight to
the front end, which REALLY helps with steering in tight-corner, on-power
situations (aka: "pushing").
This mod
almost becomes self-explanatory by looking at the pics below, so I have
opted to not include any real instructions here (details are on
Canadian-MGT's page). Just be careful when you
cut things up with your Dremel tool. There are a number of different ways
you can do this.
First
thing is to cut the side guard plate. Cut a hole on the opposite side of the
existing steering servo. Don't cut it quite full size at the beginning.
Leave yourself a little room for error. Here's a pic of my side guard
finished:
You are gonna use two bellcranks
here, so you will need to get another one.
Your next task is to mount the second
steering servo into the battery compartment (you'll have to ditch the hump
pack and get a flat pack). This is perhaps the trickiest part of
the project. Just take your time and try to make sure that the second servo
ends up equi-distant from the bellcrank as the factory servo. Be careful
cutting up the battery box. It's a close fit, but it will work. After you
get it fitted, drill four small holes for the servo mounting screws. Here's
a pic of my electronics box removed:
Here's a pic of mine finished, with
400oz of torque. Yeah, baby!
You can see how I have made
one of the arms from servo to bellcrank adjustable. Also, I mounted the
second servo directly into the battery compartment. This way, I can still
remove the electronics as one complete unit, which makes it SOOOOO much
easier to clean after racing.
It takes me no more than one minute
to remove the electronics and I can then de-grease and hose off the truck to
my content. This feature (easily removing the electronics) is fabulous and
saves a lot of down time. Kudos to Associated.
You can use a simple "Y" connector to tie the two servos together. Your LHS
will have the connector, or get one from Tower. Or you can always just make
your own. 
I use a 1400MaH flat pack battery and mount it under the pipe. You can just see the
tip of the battery in the pic above.
