I will post pics. So far, the thicker wall nose cones light not have deformed. Anything with a round and thin shell of 1-3 layers is no longer round.

Makes sense.
Ok. I am going to test this differently. The car is imprecise. I m going to use my oven.
Any thoughts.

I like the fact that this will be more controlled, but can you get the oven to maintain a low-enough temperature?
This is a nice comparison across all mechanical properties:
https://www.simplify3d.com/resources/materials-guide/properties-table/So far, I've used ABS and PA-CF for rocket parts. PETG looks like a promising option for people who can't print ABS or Nylon.
ALL PLAs warp in high heat, and this is especially common with thinner walls and lower infill. What has been discovered so far is that thicker parts with a high infill tend to warp less in the sun. This is even true with standard PLA. That being said, they will all warp with longer exposure.
Update: I am going to have to start over on the PLA prints. I had decent results and my son sat on them a few days ago. Guess what? They warped and they cracked.
You should have sold your first born to buy rocket parts by now like the rest of us. Bad planning....
PLA and summer heat do not play well together - doesn’t require a hot car.
I put up a few bird houses, and thought I had used ASA for the mounts - the roll was PLA. Two days out in the heat and they warped horribly.
Installed birdhouse
WARPED….

That is true with weight. I saw pinda probe holder do that.
Hey, all,
I just bought a 3D printer on the Black Friday sale.
Really interested if there was any more testing done on the temperature resistance.

PLA has none, PETG is slightly better. ABS and ASA are a bit better than that. Nylon blends can be quite good.

What printer did you buy?

That looks like a great printer, and it looks like you got a good deal. I spent more on my Ender 5 a few years ago and I’ve been constantly upgrading it to get basically the machine you just bought for less.
I suggest just printing in PLA or PLA+ at the beginning. It just works. Once you start exploring other materials, I highly recommend CF-infused nylon. It looks like your printer should handle it easily. The only issue (besides price) will be build plate adhesion, and this should fix that.

Thanks, BDB, I appreciate your comments. They help to make me feel more comfortable about my choice.
The plan is to get my feet wet using PLA+ to figure out how all this works.
I also bought a spool of PETG because it was on sale to use down the road.
I was wondering about nylons. Thank you for letting me know it is worth trying with my printer.

I will keep that in mind.
I was sent a glue stick of Elegoo branded PVP, but I do not know that I will need it any time soon.... I have really good adhesion with PLA+ right now... sometimes it takes more force than I thought it would to remove the prints... but I think that is a good thing.

I have had good experience with petg, better with annealing
