Being a big track, it's probably aero. Try a different body or the same body mounted farther forward. AMR12 can be very pushy in fast sweepers so if that's what you're running, try something else.

I agree. Moving the body forward 1/8 makes a huge difference. It's surprising.

Hey guys I need some advice. I tend to think of myself as fairly knowledgeable when it comes to 12th set-up these days, but every time I go to a particular track I have huge problems with the car pushing on the high speed corners. I've even gone to the trouble of setting my car up identically to other cars there and it is clearly only a problem with my car. Pod movement is free and the vehicle is well maintained.
The track is a large outdoor track used for Nitro racing as well. When I race indoors I have no such problems. The only thing I can think of is the diff setting. I tend to run the diff fairly tight. A lot of what I've read suggests that you should always set your diff the same way, while other people think it should be used as a tuning aid. Should I be running the diff looser outdoors for the high speed corners? Make sure you have enough ride height Outdoor tracks mostly have more bumps than indoors, check the bottom of the chassis to see if it's dragging, that can cause all sort of handling issues |
Thanks for the ideas. The bottom of the chassis looks clean, and I've tried 3 different bodies including the AMR, CRC Audi and Bomber R.

Hello, I am new to the on-road seane and have a few questions. A local track will be re-opening soon (Coral Springs) and I would like to know what tires for 1/12 (gen-x) on asphalt, I should use. The tires I would like to use have shore ratings and I am clueless. Do to the fact that there is a limited number of on-road tracks in my area, I can not just go to a track and ask. I would also like to know what body would be good for this track. I was told by the race director that 1/12 would be 17.5 blinky.
Thanks for the help. |
I would get Pink (30 shore) rear tires, and purple (40 shore) fronts. Both are natural rubber and have good abrasion resistance. The darker the color of the compound, the harder it is, hence white is softest and black/purple or even double purples are the hardest. I like to run a nice hard front tire, but not everybody agrees with me.:)

Thanks for the help. Check the links in my sig for some light reading, to help improve your 12th scale game |

here is my homebuilt RC supra 1/12 scale
built for as part of my GCSE Engineering project |
Turnigy TrackStar One Cell 120A 1/12th And 1/10th Scale Sensored Brushless Car ESC
is this likely to be ROAR approved? website says Timing Indicator LED. To conform with ROARs Sportsman Class racing rules and assist race organizers monitor driver compliance in non-timing modified race classes the TrackStar 1/10th ESC includes a timing mode indicator LED. At all times when the ESC is powered on and dynamic motor timing is set to a value greater than zero the white LED will illuminate indicating that the timing mode has been modified. |

Question about tires at big races(IIC/Birds/etc)...
When you guys do "one-run" tires, do you scrub them in first? Or do you run them straight off the truer? And, if the latter, do you spend time smoothing them out with a finer grit file/sander/etc? |

What also helps fresh tires is putting masking tape on the tread area and then pull it off. It gets all the loose rubber dust off and makes the tire come in much quicker.
You just wrap the entire foam surface in masking tape after truing? Then pull it off right away? |
I just blow the tires off with the air compressor after truing them.

Hmmm... very interesting. Ive never heard of this before.

Cool, thanks for the tip!

Does anyone know or know a previous thread that would tell me what my rollout should be for 17.5 blinky? I heard from 90-100mm, and i was trying to get a ball park figure. Looking to run on a track similar to snowbirds. Thank you :)
