Wasn't even referring to straight speed.
I still believe that carbon is faster in the corners, tested it back to back.
Aluminium is more constant to drive tho.

Yes, it has less flex than the carbon piece.

Carbon will yell faster speed for sure.
I'm speculating because it hasn't been tested. The carbon chassis is great in 17.5 on asphalt, but I've been looking for more steering on carpet hence the aluminum purchase. Time will tell!

That's odd, I'm looking at the aluminum chassis to help take away front traction. This car turns in ridiculously hard.

My Exo turns rather well on carpet, I like aggressive corner entry. I am running softer springs at the front tho and Spec R diff filled with 1mil oil. I have my steering set at 23 degrees on both sides.

Tq'd and won in my 17.5 class. Car was good all night. I did however go down to 2k in the specR diff. 5k feels smooth but after testing it allows the rear to break loose at times. In my USGT class I did the same with 2k diff oil. The USGT has been tricky trying to set up. It must be the tires. Two same cars and tried same setups but USGT doesn't stick like I would like. I decided to just go ahead and widen the car with some wide wheel hexes. Trying to fill out the wheel wells. It really worked. I even was able to use some stiffer springs to get some faster rotation through the turns. Did a bunch of practice laps before the main and pulled in to change battery's. Did another couple of laps and lined up. Stripped a spur!!! Oh well. Just glad to finally get some time with these cars today.

Yeah I'm not going to get the aluminum chassis. My cars are doing just fine.

From all of the testing I've done with the prototype chassis, the aluminum chassis will definitely take away front steering. I haven't had a chance to run on carpet yet, but on asphalt I've gone all the way down to an A block in the rear (XA front rear)! That's 1* rear toe...on asphalt EXO6 rotates very well midcorner in and out with excellent steering on corner entry. Sometimes you've got to go way outside the box to make things work

Sounds like I have some other areas to sort out first, still running a spool up front. I may have jumped the gun on the new chassis, oh well.

Very normal unless you have grinding noise?
It's shaft powered chassis they are always louder.

if you place your car on a stand, remove your pinion, and spin your wheels. It should be smooth, no notches and some people are able to get it free spinning for a while too.

Mine spins freely. Way more than any belt car I've had. You have to start with one gear box at a time. Make sure a gears mesh properly. You might have to add shims to get everything smooth. Then when both gear boxes are free flowing is when you install the shaft. Very important to lube the plastic gears. It helps.
