I just ran my F1 for the first time and while everything was pretty good I have a question. First, the track was fresh asphalt. I used sauce on the tires which were Shimizu 572 rear and Tamiya front. The car turns in very hard and fast. I have adjusted the transmitter to reduce the dual rate and increase the steering exponential. This helped to a point. I ended up at 75% DR and -25% EXP. I still felt it turned in too hard and fast for my driving style. Should I try to increase the caster next? What about adding more toe-out?

Also, should I try a less aggressive front wing?

You could also go to softer rear side springs and harder front springs. More caster will take some turn in out also. More toe out will increase turn in.

Try saucing only the inside half of the front tires. More toe-out would probably make it even more aggressive. A harder front spring would also reduce turn in.

I second this. Often times just a change in saucing, whether itís the amount used or the soak time, can make a massive difference. This affects all classes, but especially F1. Tires and mechanical grip are king.

Hi! I'm running Team Associated F6 too since last May when it was first released and am running on asphalt all time. All those suggestions about saucing the inside half of tyres, using less aggressive front wing (in fact, the F6 front wing is well-known for the aggressiveness, I have given up using that wing and switched to Montech front wing), harder front springs etc will certainly make your car turn in better. Would like to share my views to you so you may try too!

The M3 locknut used at the Chassis brace doesn't do the job well. I find these locknuts at left and right chassis brace will limit the rolling of the chassis at the pivot ball. I end up replacing the locknut with plain nut (Team Associated #91477, or any other plain nut should do the job). Please add some thread lock to keep the plain nuts in position.

I find 100,000cst oil for the damper tubers work for me right. I know it sounds a bit crazy on using 100,000cst but may be worthy to try and see if that fits you or not.

The kit rear shock spring is too heavy/hard for me. I am now using rear spring of 9lbs and I get good stability for my F6 rear end.

By far, I haven't touched on the dual rate and steering exponential is -20%. My camber is of - 1.5 degree, castor at 9 degree and front toe out at 1.5 deg.

Hope it's helpful!

We ran them at the Shanghai Arrowmax Cup last fall. I'm 99% sure the OEM is Sweep. But the foam felt different from other Sweep OEM tires. I was told we had the Medium fronts and 24 rears for the event. I'm guessing they were the Sweep V3 batch.

My opinion is they are a fair race day tire that can handle a 21.5 on a 1/8 scale asphalt track, but they won't last too much longer. No special set ups for the tires were necessary, even though track temps were rather cool (70 degrees F)

I have actually glued the Tamiya kit fronts on asphalt. A light coat on the sidewall can help calm the car down.

Caveat: the wiki part isn't accessible on the mobile version of the site.

The whole forum has been migrated to a new version. I don't see any wikis or the ability to create them. Looks like it happened recently.
