I
have a whole pile of Tamiya CC-01 chassis trucks and I really like them
for the small size and scale appearance. One thing I don't like
as well is the relatively poor off road performance of that
chassis. When MST started selling their CFX chassis kits with your
choice of 4 Tamiya bodies, I knew my problems were solved. I
chose the Toyota FJ40 which is a body I'd been wanting anyway and really
belongs in any off road stable. I prefer hard bodies for my trail
trucks in general, but if you are going to go with Lexan then Tamiya
bodies are the best in the business.
The CFX is a small solid axle chassis with 4-link suspension front and
rear. It has steel chassis rails and all metal gears in the
transmission. There are two varieties: the CFX has the motor
installed in the front and the CMX has the motor installed in the
middle. Putting the motor in the front leaves more room in the
middle for an eventual interior, so that's the option I went with.
The transmission is different between the two models because of the
available space, and the "F" version uses a planetary gear system.
The kit does not come with any electronics so I added my own Hobbywing
ESC and a cheap 35T brushed motor. I also added a simple light kit
and a winch. The kit itself is very good quality. If you
haven't built MST before and don't know what to expect, I actually find
their quality close to Tamiya. Everything is carefully bagged
according to the instruction steps and the instructions are very simple
and clear. The fasteners are all hex drive steel.
This vehicle is vastly more capable off road than a CC-01. With
large suspension articulation, soft shocks, and good tires out of the
box, it goes over everything I have thrown it at. It is also very
quiet which is always a bonus. I haven't made any upgrades at all
to the chassis since I really can't find anything to complain
about. If there is one thing I wish was different it is the wheels
which are just one piece plastic and not beadlock. However, for a
truck like this they actually look very good so I have no plans to
change them any time soon.
Update: Although this truck started life as a Toyota FJ40,
after two attempts at painting that body and not being happy with either
of them, I took the opportunity to convert this into a classic
Bronco. The conversion required a change in wheelbase and the
removal of the winch. I also changed out the electronics to be all
MST since I had some from another project. Now this is finally a
truck I'm happy with.
Update: This model was destroyed in the 2022 fire. It has not been replaced.
