I was just trying stuff out. I don't remember what I was trying to do.

you can shim up the difference which make the car react slightly different..or put back the correct way.
just depends on your driving style.
or move the links to low position.

again i was just trying stuff on both my cars...to see how it reacts...
tire heat, camber angles....etc.

I have found the car is quite fond of changes to the camber plates.
shim under bracket and under ball are a major setup option on the CXL.

Just started carpet season....
trying to make the rear end stick....
the flex top deck made the car stay flat quite a bit more (option deck can tweak after a hit).

I am going to try the low grip chassis in a few weeks. wish me luck

Good luck.

I was looking at the car, lamenting the lack of space for electronics with a fan in front of the motor, when I had an idea. I think if you made a new steering pivot that sat higher, closer to the belt, with downward facing balls, you could do an east/west servo mount with the linkage going under the plate. I'm gonna give it some more thought.

Because the rear hinge pin pivot is so far back, it makes things a bit crowded with the steering. But there's a lot more room with the long topdeck than there used to be.

Where are you having rear grip issues? Entry/mid/exit?

i mount the fan above the motor. (someone else on here loaded of a few pics of the same idea)
small piece of carbon fiber...3mm shim, screw down on the top plate hole next to motor...and that's it..
same air flow..
i have some left over room to space out the electronics.....and I'm running a standard size Airtronics receiver.

If I were only going to buy 1 new top deck to try on my CXL for medium-high grip carpet, should I go with the carpet spec, or the extra flex one?

Default Diff help

Guys, i hope one of you can help me to give the measurements of the Mi4 36T ball or gear diff. all i need is the distance from the outer bearing to the pulley center, from the short side and long side, then the outer distance bearing to bearing. The mi4 uses 10x15 bearings for the diff outdrives right?

Inner to inner is 16.5mm.
Inner to pulley center is approx 4mm short side and 12.5mm long side.
Outer to outer is 23.8mm. That's with 10x15x4 bearings and a shim on either side. I think the shims are .1 or .2mm.

EDIT: That was a gear diff.

Also edit: I'll sell you an mi4lp ball diff really cheap if you need one.

i have/had all three top decks.
the flex top deck is super flex. only use if you have trouble finding rear grip.
the carpet deck is great if your trying to get your suspension fine tuned, it will make the car feel more direct and you will be able to see how good your current setup is.

90% percent of time I used the standard or carpet top deck.

Anyone know what the new parts do and how they mount (other than the obvious '...more elongated flex to the chassis, allowing it to produce more traction...' as stated)? Anyone have a picture?

Look through the Red-RC gallery from the worlds. The new parts may not be exactly the same, though.

Anyway, I think you actually chop off a considerable portion of the bulkheads, and then mount the bridges in place. Then the hinge pin mounts bolt to those.

I'll probably pass on this mod, since I don't want to shell out for more bulkheads if it doesn't work well.

On the setupsheets when they say they have 4.5mm of droop on a 10mm block does that mean 4.5 mm droop if mesured from difference in ride height to fully extended shocks etc?
