Default Alu chassis for TC - anyone using outdoor

Hi

I noticed a manufacturer also producing a TC alu chassis (for the BD9, T419 etc.) for outdoor use (track racing NOT drifting).

Anyone running alu chassis tc outdoor.
Can you share your experience and findings?
Thanks.

I used it before on a well prep track on 2014 roar nationals. I tried it on my 2014 bd7 with both carbon and aluminum. It ran the same lap time on 17.5 TC just that the aluminum seemed easier to drive.

I thought alu decks were only used for carpet since it would scratch up really badly on asphalt

carbon fibre scratches pretty bad too.😁😁😁anyways you can put a chassis protector to the aluminum chassis if you want to keep it pristine, that's what I do.

I have 2 a800x (carbon) and xah evo(aluminum). The aluminum isnt allot stiffer than the carbon but it is by about 1mm corner to corner for the same torque. The aluminum is much easier to drive and faster on asphalt. So then I replaced the carbon with titanium chassis thinking I wanted it even more stiff to see what that did for me. Cars are setup the same and the aluminum is still the best combo. The aluminum is a 21.5 usgt and it runs the same or better laps than the 17.5 titanium and carbon.

Everything is identical. Except motors and tires.

My 2019 ARC with the aluminum chassis seems faster than the graphite. Our track is asphalt and well prepped. I do put some chassis protection on the rear of the car, and the ARC aluminum chassis is similar to the ultra flex XRAY aluminum chassis.

Chrisitan runs the Super flex Gizmo Chassis on his Gizmo Genesis for outdoor asphalt racing. Its really not a ton different than the carbon, it probably weighs a little more. It probably also offers a bit less flex than the carbon which allows some less grip. Lastly and I think this may be the biggest difference between the 2. Is that the carbon and Alu chassis flex different, and that changes how the car feels.

I've used it outdoors, medium grip and very smooth track. You don't want a stiff chassis if there are bumps!

Works well, I run thinner diff than with carbon, and sometimes a bit more rear toe. Easy to drive, very consistent. Operating window is smaller than carbon though, seems more sensitive to grip and temperature changes.

Talking about different chassis materials on different tracks. Does the FRP chassis have any advantage outdoor or indoor over aluminium or CF? Just curiosity.
