Default caster angle for asphalt ?

I just built a brand new tc4 . This is a team version that will be used for asphalt only . The kit comes with 0 degree caster blocks. Would this be good for asphalt racing ?. I use 4 degree caster blocks on my carpet tc4 .

Its the angle off the king pin (in 2wd cars, but same priciples apply in every vehicle) reletive to the chassis. Caster gives the axles something to "follow" on a pivot. The best explanations i have heard is from mike boylan of RCTVLIVE.com, he stated that caster is like the swivel wheels of a shopping cart. Because the angle at which the axle is reletive to the chassis (the cart) the wheels will tend freewheel straight. The same principles apply with RC cars. The more caster, the more the wheels will want to freewheel straight.

correct me if i'm wrong, and i probably am but i thought that your explanation refered to trailing axels in 2wd cars.

From my experiance of 2wd cars the more caster you run the less initial turnin you have and the more mid to exit corner steering you have due to the change in camber angle when the wheels are turned...

if i'm wrong please feel free to take the p!ss..

All is good, the principle is still the same from shopping carts to touring cars to 1/12th scale to stadium trucks (however kick up is another factor). It has alot to do with camber gain as well as weight transfer and such. Way too much about it to list here.

Here is an EXCELENT resource for all RC setup.-

This is straight from Xray's Website. The car used is a XRay T2 but the laws of physics apply to every car. I suggest you all print this and carry it with you. You guys can read this between your heats. You will learn alot from this book. I try to read a bit hear and there to learn.

Caster is explained on page 16. Some of you guys may know this stuff but others can learn.
