Hi all,

I have recently purchased a Tamiya TB-03 chasis kit.

i have installed some hop up parts such as:
- Aluminium Universal Propellor Shaft
- Aluminium Racing steering set
- Aluminium front Diff set
- Front and rear sway bars from the TA05

i have standard tyres that come with the car and the alignment is all factory set at the moment.

i am using a matrix quad magnet 19turn motor (not brushless) and LRP AI Speed Controller and a 26Tpinion gear with the standard 64T Spur.

the car sits very stable on the road, its very smooth and runs fine.

the issue i am having is this:
when i am in at least half to full throttle the steering angle is VERY wide.
as soon as the car is rolling without any throttle it turns much much sharper.

what should i do with the car to make it turn much easier at higher speeds? its not as if the car is drifting or loosing traction. it just has a ridiculous turning circle when its moving quick.

is this just standard or am i missing something here?

thanks

Nick

Hi,

If you're using kit tires, likely you are exceeding the adhesion limits of the tire at that slip angle.

A couple things you could try: remove all spacers (if any) from the front rockers. Also, give it some toe out in the front.

Or you could also change ackerman. Instead of hooking your servo tie rods up to the outside holes of the front knuckles, run the inside holes.
One last thing you could try to increase front end traction is to run the front rocker tie rods on the inside most holes for the lower a-arms.

Both of the above will give you snappier turn in. If you want to reduce rear traction, try standing the rear shocks up more, or putting in a stiffer rear spring.
