Hi Oleg,

That's a great result. Car looks short, may I ask the wheelbase length?

Thanks.

259mm +/-2mm depending on front and rear caster angles.

259mm during this test session.

Rear castor?

Yes.

Our rear suspension is similar to the front one.
It is possible to adjust rear castor, toe, bump steer etc.

We are using rear castor now to change wheelbase length.

Sounds rather strange... I can't think of an effect such an adjustment would make other than wheelbase...

Hey is there any chance you can up date the website (www.awesomatix.com) with more recent data. I would love to see some more of the details that the site is set up to show.

BTW what is the the weight of the core chassis (complete minus wheels, body, and electronics). It looks heavy in some areas and very light in others.

Hello

i have a question:

I'm really curious about these small shocks, they use silicone oil, which is the operating system???

Best regards:

Yes, this car is a bit strange in whole.
But it is really possible to change wheelbase of this car by means of rear + or - caster addition without appreciable influence on others parameters.
But it is necessary not to forget about additional adjustment of rear 'bump steer' in this case also.

Current samples of chassis with all steel screws, sway bars, alum. battery holders and servosaver:

~510g for transverse motor configuration
~495g for longitudinal motor configuration


pmc - Shocks are rotary damper type with special liquid inside.

Maintainable? Rebuildable? Tunable? Source and type for the "special liquid"?

These shocks allow to adjust the damping and spring rates without
replacement of the shock’s fluid and spring.

Our dampers are factory assembled and fluid filled already (the same as in the real cars).
Don’t disassemble our damper’s casing to avoid a loss of damping rate.
But it is possible to replace some outer parts if they will be damaged.

There are two damper action modes: symmetric and asymmetric modes.
At symmetric damper action mode the compression and rebound strokes
are equivalent. At asymmetric damper action mode the compression stroke
is softer than rebound stroke.
You can easily switch between these modes ( but not on the run).

"Special liquid" at current stage - silicon base with some rheological additives possible.

I found this -

Rheological additives play a major role concerning storage and application properties of liquid systems. In waterborne coatings they have a major influence on such key properties as vertical flow, leveling, gloss, film thickness, covering power, spattering tendency, brush and roll resistance, sedimentation tendency and pigment stabilization. They have always been an important component in the production of paints and lacquers. Even at the beginning of the production process, it is possible to optimize the energy input into the material to be ground, thus leading to a better dispersibility in those systems. At the same time, rheological additives can considerably improve shelf life by reducing the settling tendency of pigments and fillers in a paint or lacquer formulation. Without adequate rheological control, those systems very often show syneresis effects. With spray application, an optimum compromise has to be found between good vertical flow characteristics (to achieve an adequate film thickness) and good leveling (to obtain a smooth finish). For this reason, in the low-shear range, the viscosity must be set just high enough to prevent vertical flow.

Price and availability to the US.
Want to buy one.
Almost 2 years.

That seems quite light.... From memory most TC's are about 600g.

Am I correct in seeing little bearings on the swing shafts? It looks like a little bearing held on with an E-clip that runs against the diff outdrives. I imagine the wear would be no existent!

How much steering angle can the CVD's achieve before they start chattering (inside wheel)? They look to be a little freaky too...

Front CVD is double joint type ( similar to Losi LCD in action) so there is no chattering.
Rear CVD is normal type and durable according our tests.

Both front and rear CVD's are assembled without any set screws.

45 deg. is max operating angle for both drives.
