Wheel Allignment settings

[ozwes007]

Can any one advise the ballpark for wheel allignment settings for a Nitro 1/10 scale SBR Falcon(Australian). Has Caster camber, toe settings for front and rear.
Currently I am running Negative camber on the front with 2mm toe in and negative caster. On the rear I am running Zero toe in and very little caster.
It seems to be very twitchy under acceleration and has a tendency to power steer right and left. Should I use more front drive or less. I am currently using 3% more front drive and it seems to steer better at high speeds.

I'm not sure about that specific car, but normally you want about 3% toe IN for the rear. It keeps it tracking properly.
On the front, you can start with zero, then try 1 or 2% toe OUT and see how it handles.

Are you sure about the toe out on the front?
I build rally cars, drag cars etc and they all use toe in etc. seems strange to use toe out, but I know nothing about 1/10 scale cars and how they react under acc. or braking. Could you elaborate a bit on this.

As I mentioned, I'm not familiar with that particular car. Toe out seems to be preferred for off road dirt runners, that's why I suggested starting at zero and seeing how it behaves. Anyway, you DO want tow in at the rear.
Wait for someone who knows that car to offer more advise.

Start with Rolex's advice, if you still don't get the car to steer how you want you need to play with the suspension settings. Front/rear spring rates, camber, caster, ackerman, roll center, and droop all play a role in how well your car handles the turns. Your particular car might not have these adjustments.

Some good reading for you.

Had a look through the above, and picked up some good advice. I usually work with real race cars and it seems small scale stuff reacts slightly differently.
Thanks guys I think I have a handle on it.
