Hey,

I am wondering if there are people with a hole lot more knowledge about diff settings. I Know about stiffer back makes more stering softer front more stering ect. My question is in reguard to small tight tracks. This would be a road corse track. They will be starting some time next month and I might try to find one in a week or two.

Well I just wanted to give you insite and explain why I wanted to know but to be honest I know more than I make it seem. I have tested several settings but since I can not test these on the course I am hopeing someone could shed some light. A pperson that races alot and how they do their settings and all. First off I have a Nitro tc3 fully aluminum drive train and arms. Titanium chasy and turn buckles. I have or use foam tires when I will be raceing. I have the car set up to what I feel is the best settings for toe and camber front and back. I am just hopeing someone will know this answer.

Question.

Ok if I want to have the car turn tighter but not have to slow down should I make the front as loose as possible and tighten the back up. lets say we devide them up in 1/8th turns or steps. This will allow 6 steps. 1/8(Tighter) to 6/8(Looser).

Front 2/8 back 4/8

is it better (for small tight tracks) to have say
Front 1/8 back 3/8
or
Front 3/8 back 5/8
or as low as
Front 4/8 back 6/8

I did not know if it was the differance between the two that made the car turn tighter or if it was just the setting of one was like 2/3rds and the other was 3/4ths of the whole picture.

And most importaintly which ones is the most importaint to have correct.


Exzir

isnt stiffer in the front makes the steering more tighter and weaker in the back springs?

No stiffer front makes less steering. You want the out side back wheel to have more drag than the front wheels to make a tigher turn. A looser back wheel will widen the turn of the car.

From what I understand, a stiffer front diff will reduce steering and increase stability exiting the turn. A stiffer rear diff will initially make the car harder to steer entering the corner, but once the rear traction is broken on one of the wheels, makes the car over steer. I am not sure if there is an exact science to this, but you just have to play with it. This is the stage that I am at. And throw into the mix different springs, roll bars, tires and shock settings.[sm=drowning.gif] It is a challenge to say the least.


Scot

Well Scot the other settings on the car are for weight displacement. I am in no need for weight displacement anymore. My weight displacement is in greate shape. I am into the area of diffs since this is the one setting that does not care about weight. Sway bars and ect are all about how much weight it places over the back vrs the front. Diffs don't displace weight directly they allow the tires to force the turning of the car more or less. I am really tring to find out exactly what part of the euation matters most the front diff settings or the back diff settings. If I were to be in a large track then diff would not matter much and my settings would be excalent but I need tighter turns and all with out the back tires giveing way.

probably of no use at all, but the very fastest of all RC cars the 1/8 on road cars run a front one way & solid rear axle! they even overdrive the front wheels in comparison to the rear by changing the pulleys[X(]
those things handle like no other[8D]

Well I am sure my 1/10 car would handle extremely well with some of them 1/8th cars you are thinking about. Since I am talking about a tight track a 1/8th car would not fit around the turns. a 1/12th car does alot better than my 1/10 car since the car is smaller. The larger the car the more room is needed for a turn. For instance I can u turn in under 10' that is from the left to the right. A 1/8th car needs anywere from 18 to 25 feet to u utrn. From one ways are a joke in a tight track. If you have a one way in the front the first time you hit the brake it will go spining out.

sounds like you haven't seen a 1/8 scale car run

Dude I have and I know alot about cars. Infact I know that the 1/10 racks are smaller than 1/8th scale tracks.

I know that a really good 1/10 scale car can handle corners extremely well. Infact the lighter a car is the better it will stay or grip the road.1/8th scale cars are nearly a pound heavier.

I am going to find some movies you can watch over the internet of really good 1/10 scale cars run. I have attended 1/8th 1/10th and 1/12th races the lap times are better for the 1/12th then the 1/10th and then lastly the 1/8th. Larger tracks the 1/8th cars are better than the 1/10th but not tigher tracks. I have a question do you think a 1/8th car can handle a mini track. These tracks are or will fit in your single car garge. I know this sound redectues but think of this way do you think ytou car would be able to drive on the 1/8th tracks. Anser is no bigger is not always better.

you can find some movies at www.wildhobbies.com

1/8 on road cars are only slightly longer & wider than the 235mm foam tyred 1/10 cars
and as for saying a small track that fits into a garage ***!
thats a bit like saying your Bit Char G handles better on your kitchen table

i've run with 1/8th scale cars on a 1/10scale track in Jersey and the track is pretty small and they pretty much out handle and out speed most of the 1/10th scalers on the track. most of the cars are mugens and serpents and to say 18~25 feet to turn is not true and all these cars come stock with front one-ways and they don't spin out. even a clumsy HPI super nitro will turn on a dime if dialed right. and it's a purpose built big basher. 1/10 don't grip better and 1/8th scale cars don't grip better there proportional to the size. 1/10scale tracks are smaller cause why use so much space for 1/10scale cars.
