For me these Basic Setup Sheets are kinda worthless ....
The only difference between Carpet and Asphalt is the difference in downstop values.
In the video Ronald made with Tonisport & Mugen Seiki, they are mentioning that the car comes with 4.25 and 4.5 springs. "prepared for the upcoming outdoor season in Europe"
Both setups mention a 4.5 and 4.75 spring. It seems, that these basic setup sheets are already outdated or were never proper setup sheets.

I am aware that with a good balanced car the differences between carpet and asphalt setups aren't that drastic but these sheets seem rushed, at least to me.


Good to see Ronald in the mix at the ETS in the Apeldoorn. On pace with everyone for P2 except for Michal continuing with his "Alien" performances for the past 2 years
P2 in Q1, flipped in Q2 and in Q3 had a weird spin in his penultimate lap while battling for P2.

On carpet the MTC3 looked already super dialed but on asphalt the setup probably still needs some work.
But to be in the mix for the top spots on the first asphalt outing of the car in "normal" (not TITC) conditions looks promising for the MTC3 platform.

Cruz is running a steel chassis. Not sure if Volker is on it too.

Really……I thought this car was aluminum chassis only.

The Kit is aluminium chassis only.
If i remember correctly they stated in the official release that a steel chassis is in development and will be a option part in the future but no release date was mentioned.

So steel will be an option I guess. Hopefully its not priced like the Awesomatix chassis.

The awesomatix steel chassis is no more than an xray alumn chassis....

That's exactly what racers are afraid of...Nothing should be in the same price range as Xray(overprice) parts period, or else folks will think price gouging....

Please send me a link to just buy the AMX chassis. Just the chassis, not all the bulkheads and stuff.

Ohh Lord ....
The price discussion posts are incoming. The steel chassis isn't even out.
Tariffs and NiMh / Brushed Motors are next.
Can you keep that in the Awesomatix or TC8 Thread

I'm also curious if a potential steel chassis will keep the standard srews.
I think Mugen was able to get away with standard screws because they are offering a 1.5mm chassis so the countersunk part of standard M3 screws aren't protruding through the chassis too much.

The only steel chassis that is really raceproven in my opinion is the one Awesomatix offers at 1.2mm thickness and therefore needs 110° countersunk screws so the whole screwhead interfaces with the chassis. If you want the whole head of the screw withing the chassis thickness (e.g. for durability reasons) different screws are most likely.

I don't know the exact numbers but the Awesomatix Steel Chassis is around 30g to 40g heavier than a carbon or aluminium chassis with "standard" thickness.
If you increase the thickness from 1.2mm to 1.5mm at the same footprint, it would increase the weight by another 25%. And maybe more important the flex characteristics would change dramatic, if not compensated in other ways.

AMX does not use 110 degree screw heads. Its a normal counter sunk head but is called a shallow head 3mm screw.

RC Maker has a prototype steel chassis. Antoine was using it at ETS.

Thanks for the clarification, my mistake
I think i mixed it up with xray. They are using 110° head screws for their 1.5mm aluminium chassis.
But i think everyone gets the idea what i was trying to convey.

My understanding from the person who knows MTC3 the best, 1) steel is expensive and very hard to produce, 2) weight balance of aluminum is better as weight can be added more to center rather than distributed to the extremities as in steel.
