What have you done to maintain/enhance continuity, or power distribution from the base to other parts of the track? Have you crimped all the rail tabs at the joins? Have you installed power jumpers/taps around the track?

What have you done to enhance conductivity, or the power transfer from the track to the car? Most SSD users find that a drop of INOX MX3 on the braids, or carefully applied to the rails around the track greatly enhances conductivity.

Those two things, together, have massive effects on the performance of cars. If either one is not considered and taken care of, then car performance will suffer.

After, and only after, both of those things are taken care of, is it worth considering providing more power to the track via a larger power supply and a modification to the power base.

 

Hi
This is a useful fun LINK on how to improve continuity when using plastic track

 

Thanks to Mr Flippant and Ade, I wil check it out

 

I think the problem is solved.
I read a topic about some similar issues and tested the throttles.
The one I normally use wouldn't go in a steady line when I pressed the trigger, it was
like going to full speed almost immediate. When I did the same test with another throttle
it was more steady going from low to high speed. Tested the throttles while holding the cars rear end over the track.
So I put some WD40 on a cotton stick and cleaned the metal where the throttle inside is moving, wiped it dry and now
its running like the other throttle, and the car is not going crazy

Hope it will be enough to tame the cars

 

ah, a dirty controller. Well spotted!
