I mentioned I thought your setup was bonkers, and here's my take on why - it seems to have a lot of changes which cancel out other changes in terms of sidebite.

You mentioned having to dial out rear end grip - according to your setup, you only put additive on the rear tyre, so that's hardly surprising!

If you could take us through your setup and explain why you made certain changes (e.g. 0 deg camber on the front - that one baffles me!), it would really help!

if I have this: RF Hingh Pin Mount: ^^, then I will get anti squat, right? What effect does it have?

@ Colmo

The zero camber at the front is for the tire wear.
The E4RS has tons of grip at the front so you have to reduce it a lot and the zero camber also gets ride of the grove wear on the inner side of the tire.
The TM eats front tires if you have to much camber at the front.
For some reason it is a lot less on the rear:weird:
The spacer under te rear turnbuckle on the bulkhead reduces a bit of side bite but it also makes the car predicteble turn in and out(at least that is what i noticed on the carpet where i drive)
The ride high of 5.5 is at standstill and when putting on the power it lowers.
Also if the car is at the same ride hight front and rear or even lower(at the rear) you get a bit of funny steering
The tire traction that is none present at the front was at the end of the race when the grip overall increases.
Normally i start with full at the rear(and keep it) and half on the front what will change according to the level of grip.
I like a car that is a bit understeered and not one that is oversteered.
Hope this all makes sense:D:D

Current Setup : Carpet
 

After more guess and test sessions at my local carpet tracks this is where I currently sit with my setup.

I am very interested in finding out what others have found out about this car to improve it's feel on carpet.

Driving Feel:
-A little pushy and lazy on corner entry.
-Tight through center.
-As I race stock my setup is built to maintain highest mid-corner speed.

Largest Improvements (Order Of Magnatude Improvement):
Adding lots of droop improved the car everywhere.
Going from 25wt oil to 40wt oil in the front end. (drastically kills the steering).
Moving the steering bell crank to the rear most position.
Moving Shocks front to #2 and rear to #4
Shimming the front end out to the max. (reduces traction roll)

Cheers for the explanations, Roy - those are probably more useful than the setup itself! Knowing caveats about the behaviour of the car allows us to make informed adjustments!

Capt'n Slow - cheers for that, could you just make it clear that's a foam setup, and is it an FS or RS? Roy and I are talking about rubber with an RS.

RS chassis using jaco rubber tires (Medium Grip or Shore 32) included the shore rating as other clubs run the sorex equivalent.

My apologies, I always associate Jaco and shore ratings with foam. Thanks for the clearup!

Your welcome Colmo.
We all need to help one another to get this car to be great and get as much info on what setup to use on what surface indoor our out.
I am going to race this weekend again on carpet and going to take a Sakura Zero to it's maiden practice and compare it to the TM E4RS i have.
I like the TM indoor as it can take e beating without loosing parts in the mayham:D
It also is very consistend and funny thing is my lap times are quicker on used tires then on new rubber.
Perhaps it is my setup but i like to run on at least 3 or 4 heat old tires(indoor that is).
If i race outdoor on asfalt with the TM i have to use a harder tire at the front to keep a even tire wear all around.
Perhaps this has something to do with my driving skills but with my Top Photon i can drive with the same tires all around and still get the same laptimes.
I love all the cars i have.
All have there plus and minusses but overall i like them all.

regards Roy

Hello all,
Just in time for Christmas I have 6 lightweight, aluminum lipo trays for the E4 ready to ship.
Some of you already use my trays and the rest of you should if you like to have extra clearance for those taller lipo packs. If you know someone who is running my battery trays please ask for their opinion.
These are all going for $55.00 shipped in the continental U.S. and $50.00 each if you buy more than one.
They are exactly as you see in the pictures and from what I am told, they will fit all versions of the E4 carbon chassis.
Keep your CG low and lose those spacers!

Is there a new E4 due out soon - I only ask because the UK distributor is selling the E4RS 09 for £249?

Hmzzzzzzz that is the same numbers but in euro's as the E4RS is here in Holland.
Not much difference between the E4RS and the E4RS 009 tho.

cheers Roy

Stephen, I think the man to ask is Martin Askell.

It's inevitable that a model that is now 2 years old would have to be discounted to maintain sales against the newest, shiniest gear coming out - I've noticed TC racers (certainly in comparison to off-roaders) change chassis as often as socks....

Found the fit and finish on this product top notch. Fits my SMC 5200 50C battery without an issue and I still have 2mm of top deck clearance for the screw head on the steering system and the middle k-factory chassis stiffner.

As an added bonus overall chassis stiffness is improved as well. Check out the attached pictures to see the fit for yourself.

"taps fingers and looks at Yodog" Where were you last month:weird::confused:;)

cheers Roy

I spoke to wolf from wolfhobbies their is no new car comming out yet from Team Magic. But wolfhobbies is testing some prototype parts for the E4.
