ETS Final Race in Slovakia
Hi Paul,
What will be your basic setup for ETS Final Race in Slovakia !?
I am usually race in carpet track & I have absolutely zero experience for asphalt tracks.
What will be my car setup changes !?
Hope to see & meet with you in Slovakia...
Have a nice trip...

A copy of a question on the Xray forums, but wondered if you have any advice;
What sort of changes do people make when the track temp gets a bit too high for the temp ratings of the tyres?
For most race series we have a spec tyre, so if the track heats up too much we just have to make do.
My setup seemed good on new tyres, but was immediately a little loose from the second run onwards.
New tyres with the hotter track temps (50-55degC) worked OK for a few laps, then they went off as they heated up too much.
This was with Sorex 32RY's
Different additive regimes didn't seem to make much difference, so is there anything you might do with cambers, or links etc?
Thanks

Hi, their are a couple of key things that can help but their is nothing that will cure it completely. First i would try softer springs all around and lower the car a bit, this could help some by reducing the load spikes on the tire. second i would definitely be using a oily additive, LG2 normally works really well on a hot clean track, put on a modest amount and let it sit for a long time, should not be greasy when you go out. lastly its all about driving smooth, especially at the begining of the race, even if you have to drive super slow you cant slip a tire, it will be fastest in the long run.
hopefully that helps a bit. Thanks

If you get 3 4pks of tires and you run 4 quals and a main you can run this tire strategy for all quals and the main.
Paul have you tried this?
#2331
I know in hot races in the past if re-run rear traction was a problem at spec tire races guys would run a new set of 4 tires in Q1, for Q2 they would move the rears to the front and put 2 new tires on the rear repeating this process for additional quals. Depending on how man sets of tires are allowed this strategy might help. You just have to make sure you car is set up to turn on re-run fronts.

I was using thicker additive with warmers set quite low for a while, then wiping off and reducing the temps on the warmers even further, a few degree's above ambient.

Our national in two weeks is 3 sets of 32RY's for 5 quali's and 3 finals. (If the temps drop there won't be an issue )
#2334
I have balanced the rear pod in the past but i do not currently. The chassis i will balance on pins or at least get it close. you can also then ballance the car as a whole and it will be fairly close. I would not add weight, i would move the battery until the balance is better and if you cant do that i would move the electronics around then.
Thanks!

hello paul
how long do you do with a 64dp spurgear you replace it for each race?
greetings peter

Hi Paul,
Thanks for an exellent interview on RC Krackin. I have a question for you. When I picked up my T4 a fellow racer said to get more and the proper stearing I would need to offset my servo horn to the right a little and add 4mm of shim at the bottom of the link coming from the servo horn. Can you please explain this for me? Thank you

Was any new parts tested at the ets race

hey Paul,
I know you seem a bit down on your performance at ETS but we are all proud of you here. That's some seriously tough competition and you did well.
Last time I was on here I was struggling with a wiggle in my car coming out of faster corners running mod at Leisure Hours. I had tried to mimic your 2013 Nats setup but I ended up going back through the car and found a couple things that were not what you had. I reset the car with your Nats setup and headed out this week. No more wiggle! I did discover the rear toe was only at 2° and I think that played a big part of the problem because it didn't lock the car in under power.
What do you think about springs? Have you tried the progressives all around? I changed from the 2.3's in your setup to the soft progressive springs and the car stopped lifting a tire in mid speed turns and was better under braking. That made it easier to drive for me which was good but I wonder what a firmer spring like the 2.5's or firmer progressives all around would do.
Thanks,
