Further Setup Changes

I changed some settings on the Gambler now and I will explain my thinking behind that.

To enhance front end grip in slow and medium speed corners I changed the inner pivot point of the upper front wishbone to the outer hole (inner hole is stock setting). This gives more camber increase, when the frontend is compressed and therefore gives a more constant steering while cornering.

I also increased front camber to two degrees to stay below 0° camber unter hard cornering (stock setting gives positive camber during hard cornering)

Front toe: As the steering has a lot of Ackerman, I decided to run no toe at all. Normally I run a little toe out to have a more direct turn in. But you have to sacrifice straightaway-speed for that.

With this car I am able to run neutral toe and gain more speed on the straight, which is very important when you only run 17,5T Motors.

Of course with neutral toe you also have a better turning angle on the outer wheel, which should increase steering even more.

Next I now use 2 hole shock-pistons (the ones that came with the car) instead of the stock 3 and 4 hole pistons. They have to be sanded quite a lot to make them fit perfectly. Because the first race of the season is on a high grip artificial turf track I tried 65WT oil front and rear, which is a quite stiff setting. 45-50WT should be a normal setting for this truck.

But I want to try out how the car behaves with a lot of dampening. The goal is to decrease body and chassis movement in the fast chicanes and to get more predictable jumping. The results of this I can only tell after the next testing session (which might take a while this time)

I kept the white Traxxas Slash springs, which seem to give very good results. All in all these changes should make the car even better for upcoming race.
