I thought his car looked really stable in the first two rounds. Then as the track warmed up his tires went away or his set-up changed? Not sure since I didn't talk to Russ much about it. He did mention he thought the foam on the track from the foam tire cars might have been a issue also?
I've seen this at other on road tracks both carpet and asphalt when foam and rubber are used on the same day.
Before the gas guys got there Al & I (both with the same tires 45s) had good traction and as the day went on it seemed to go away or get weird, I'm not sure which.
I need to run there more to get a feel for the track.

I found it strange that I was able to race 27s tires on my 1/10th Mod car, I have never been able to run that soft of a tire without overheating them.
I made 2 changes to the GT car, took some droop out of the front & it gave me more steering but the back end was too loose.
I made the rear links longer at the hub, that made the rear looser.

I'm curious to see the laptimes for nitro vs electric running at the same time on the track. From what I have observed/experienced, although the top end during race conditions are similar, the acceleration favors the electric cars.
I also believe that the firmer shore ratings will help tremendously for hooking up with the GT8E cars. I believe they will be available soon. I can't wait to try them.

Das ran 24.2
Give me a week or 2 and I think i can beat that but it wont be by much

I made the rear links longer at the hub, I could not get a feel for the track, just seemed weird

Also looking at the tire pictured, most of the "gatoring" seems to be towards the outside of the slick; meaning a little more negative camber is needed. It would also reduce the heat on the slick's edge and distribute it a little more even across the surface area.OK

Since the electric cars are generally heavier than their nitro counterparts and have instant availability of monster torque, I believe it is much easier to overdrive the tires given the same shore rating.
GT8E is pretty new to most, so getting the tires, setups and etc perfect is all happening as we type. In time we should have a multitude of great references to use as starting points. Great thing we have this thread to document it.

Looking at the pic, I believe that is tire degradation. We have 0 racers using foam on our local track and my tires looked like yours. I believe it to be a result of too soft of a shore for the temps they were used on. I'd love to try some 60 shore compounds with FIRM inserts for GT8E in the upcoming tripple digit temps we experience at our track.

They sucked. push like crazy and never did warm up car was lose the hole run.
An other guy there had sweep's no idea what tire with custom foam they worked really well.
PMT tires work ok and I turned my best laps on them. but they are a handful the first 2 mins then they start to work about as good as the guy with the custom sweeps.
in the 3rd round Custom sweeps turned in a 24.56 and I turned in a 24.52
Air temp is 65-69 cool breeze
track prep is water and pop syrup.
Going to try sime Impinama's this week I hope, I will report my results.

1/8th and 1/10th nitro racers get 2 to 3 minutes on the track to warm up engines and tires, maybe a few laps to warm the tires would help.

2-3 mins of running isnt really ideal. not yet anyways.
5000 Mah is good for about 9:30 of run time. maybe a bit more.
