one would think that more weight up front would give more steering as its putting more weight on the front tires. i think of it this way, if you put the weight in he rear its gonna cause the rear end to swing more in the corners, like a pendulum effect, correct ?

I put 4.5oz in the frt of mine 2 weeks ago. I have only had it on the track once since then on a large outdoor track. It seemed more stable and jumped better.The weights will fit under the servo.
If I want my car to turn less, weight is not the first option where Im looking at

Of course not, but it's not just about weight. It's about weight bias. Out of the box with a 550 motor and a stick pack the sc10 has a 42%/58% front/rear bias. This is in stark contrast to most 4wd rc cars. Most are much closer to 50/50. My 8th scale buggy is 48/52. This is the a big reason why saddle packs are used: moving the weight forward. There is only so much mass that can me moved on the sc10 and since weight is typically added anyways most people put it behind the front servo or in the front left corner if they are still running a stick pack.
Somebody remind me, didn't I write a manifesto about weight bias issues on the SC10 4x4 a few month back?
That's right, I did!
Next thing you know, all the cool kids are going to be doing it.
Thank you Dirt for validating my life.

lol, That is for a 550 right, I run a 540, is it still off by a lot? I mounted my esc far back on the left with a stick pack config and added weight to the rear 1oz....... so your saying , this is wrong, lol.
If you want the chassis to have more transitional steering, moving weight to the back helps because it increases weight transfer by putting more weight in the rear to transfer.
If you want the chassis to have more steady state (like a sweeper) steering, putting more bias to the front helps.
Before they outlawed moving ballast and spec'ed F/R weight bias, that's exactly how F1 engineers balanced the tire temps F/R. It's gone this season, which is one reason why they are having so much trouble with tires on one end or the other going off and destroying the balance.
