i seriously doubt if the guys kicking my ass on the track buy this car i will all of a sudden be faster because of a little extra friction.

Right now all we have are the pictures. So questions are as natural as dirt. And just as messy!

I admire the tech. Always.

ah, so they did go the route of shimming the upper bulkhead for RCH adjustment.

very interesting manual - lots of adjustments possible including inserts in arms in line with more inserts in bulkheads.

I actually think the camber setup with shims is cool - anyway camber is a set-at-1.75-degrees-and-forget setup...

How does one bleed the dampers?

Manual is a bit disappointing, they should have been more detailed about building the shocks and general setup. Hopefully they will have the videos up before people start building. Now just waiting on a US distributor.

Ok, this is going to be a stupid question but I don't know so whatever. Why do they use a heave shock in the front but not the rear? Can someone explain the heave shock?

Not a stupid question at all, I just searched heave suspension on Youtube. Seems to have some pretty good vids on it.

The heave element prevents the front end from bottoming out during pitching from braking. Only effective when both the front suspension is compressed. During cornering, the heave damper doesn't come into play.

Pretty disappointing to see the adjustment for camber/caster relies on shims. pretty much eliminates any quick adjustments and require the 2 ball stud to be completely backed out, guess the thickness of shim needed, reassemble everything, put the car back on the setup station, just do repeat everything again if its not enough. Also with all these loosening and tightening of the ball stud into plastic arm, its just a matter of time before you strip those threads.

I have a feeling a lot of people will just adapt the Awesomatix style double turnbuckle upper arm instead.

someone will come up with shims that's basically the shape of the rcmaker arm clips for the AX and problem solved. Just back it out enough to add and remove the shim, retighten and boom, camber change done.
With all the fullscale prototype / openwheel inspired design on this car, I'm surprised they didn't rip a page out of that book either.

Exactly what I was thinking - horseshoe shaped inserts would make setup changes much quicker. If the chassis is rigid enough, a setup station is needed only for confirmation and setup shouldn't move even after a crash.
Well, it would work that way, if they included some setup table in the manual... The whole manual feels a but messy, without explanation how can you change the setup.

Can someone explain to me how to set the caster.
I don't see anything there that I know from the MTC 2, for example.
