HPI hop-ups

There are some hop-ups I am considering for my MT, and would like some
feedback on...

1.  Sway bar, is it necessary?  How much of a difference does it make?  The
truck is already low enough that I am really not concerned about rolling it.

2.  Front one way diff.  If I am correct, it will be "under power" when
moving forward, and will spin free in reverse, right?  Would it also have
less rolling resistance?  Is it worth the money?  What are the real benefits
of this upgrade?

3.  Motor plate/heat sink.  You know, the heatsink version of the aluminum
plate that the motors screws on to...Does it make that much of a difference?

4.  Stainless steel hingepins...are they really smoother than the stock
ones?  With no shock attached, my suspension is really smooth already.

5.  Various graphite parts...any thoughts at all?

6.  Front and rear HPI universal dogbones.  Are these better or worse or
comparable to MIP's?

I really appreciate the input.

Hi, of all the hop-ups you mentioned, the universal dogbones are no,1, that is
assuming that you already have a bearing kit installed.  Graphite parts can't
hurt also.  As for the rest, unless you have deep pockets, forget it.
good luck

You were saying your motor gets really not. I don't see how this could hurt
anything. I wish they made one for the Stampede.

The graphite is lighter and are gonna be a lot stronger then the plastic.

I just bought a MT yesterday, I was lucky it was new but assembled.  It has
the super shocks on all corners plus it has the motorplate you are referring
to.  The motor plate really pulls the heat of the motor.  I noticed the top
of the plate was hot which is very good.  I suggest the motor plate and the
CVDs from MIP.  The CVD's  are rebuildable and I think they work better.  I
noticed with the stock dog bones that when I over steer the front wheels
lock up (not good), the CVD or any universals will fix that.

p.s. The normal CVD are $25 a set and the shiny's are $30.  The HPI's retail
for $34.  Just thought I should mention that...

Hi I have an MT thats tricked out for off road racing, here are my
thoughts.

I have never tried a swaybar before on an off road car/truck.

I have the one way PULLEY on my MT and really like it a lot.  It is
somewhat similar to the diff except the one way device resides in the
small drive pullies, and I think it is a little more efficient.  It
allows you to swing the rear end around on tight turns by tapping the
brake and turning the steering wheel.  It's a real trip... tap the
brakes, swing the rear end around and floor it coming out of the turn.
you get 2WD brakes and 4WD power.  The real key though is setting the
rear end correctly to get maximum rear traction.  If the rear traction
is set too loose, it will fishtail the second you let off the throttle.
I deffinately think it is worth the money, especially if you race on a
tight track with lots of turns.

I haven't tried the heat sink motor plate.  I guess it can't hurt.  My
MT gets HOT HOT HOT HOT!!!  One of these days I'll try it.

I haven't found a need to replace the hinge pins yet... still running te
stock ones.  My MT suspension is as smooth as any other RC car I have
(XXCR,  T2,B2,GT).  I will probably upgrade when the stock pins bend or
wear out, but that will probably take a while.

Haven't moved up to graphite yet.  I don't usually upgrade unless
something brakes and I need to replace the part anyways.  I did check
out an MT with the carbon fiber top front plate, and the stock chassis
is deffinately stiffer with this part.

I've been using the HPI universals for a year or so and they seem to be
holding up great.  I'll replace them with CVD's once they wear out
though.

LAter,
GArrett

the only thing i saw on your post that I would buy for my MT is the
universals(I would buy the CVDs, due to positive experiences with them
on NRS4 and NRS4 mini), and that is only for the front, I think they are
unnecessary for the back wheels. I bought mine after the dogs wore out.
DO NOT buy a one-way if you have a reverse ESC, the one-way is designed
to move, umm, ONE WAY? going in reverse will destroy it. The front
wheels "free-wheel" under braking, not reverse. I have a theory that the
one-way diff was invented so that the old 2WD pan car racers could
modify their newer 4WD sedans so that they behaved similar to their old
2WD pan cars under braking conditions. I still havent been able to find
anyone that can convince me that modifying one of my sedans so that when
I hit the brakes, I only get 2 wheel braking,(by adding a one-way)
rather than the full 4 wheel braking with the standard front diff.
luvya!
