T&A Vintage Racing Fine Tuning

Fine tuning for the Ferrari 375/Vanwall racers.

A lot depends on how much experience of RC cars you have had before.
Also a couple of you have mentioned to give it to your 6 year olds.

If you have had lots of cars and experience before this will most probably not apply to you
as you know what you are doing.

The first thing in my experience is that no matter what the age, 6-80, the first response of
someone trying a car for the first time, is flatten the throttle and straight into what ever
object is in the way, this is not like the other of Andre’s car, it is a fast racing car, capable of
at least 30mph 50KPH.

My first thought would be to get a transmitter you can control the throttle travel, and end
point steering adjustment, and adjustment of steering centre this is vital for its long term
survival of the car.

Set the throttle to about 20% for children, and old geezers wanting to try, (My friend will
know who he is) and 40% (as I did) to get it sorted, tuning, testing straightness of steering,
it will probably wander a bit until you fine tune it. Spend time learning what the car can do
before you attempt to go fast, you can easily take off a wheel as its an open wheeled racer.
The beauty of using the TT02 is that replacement driveshafts, suspension arms, etc are
readily available.

NOTE the wire wheeled version is quite a bit faster, as the wheel diameter is bigger. The
smaller wider ones means it handles much better as it is lower and more rubber on the
road. The new specialist tyres also grip much better than standard RC tyres.

There are steering stops on the bottom of the chassis. You need to set the steering travel to
0 then work it up to just touch the steering stops each side. (mine needs about 40 % of
steering travel to work.) If you put it without adjustment , the servo of 20/25 kg can rip the
car apart.

Once you have the steering travel set, you need to adjust the Toe/in/Out.

This means the front wheels must run together, or in this case toe out by 2mm, this is a
good place to start, you can maybe refine this even more later.

This means that put a straight edge each side of the tyre preferably on a spacer each side to
reach the middle of the tyre, and then set the adjustable steering linkages such that the
front of the tyre is 2 mm wider than the back. This will stop it wandering as much, mine now
tracks Great.

The front crumple/ bumper section of the body will help save the car in the slower impacts,
but probably not much will help in a full throttle impact. We have tested it as much as we
can but have not tested full throttle impacts which would although the car is really tough
lead to its destruction.

Also saying that, you must realize that this is a serious R/C racing car capable of at least
30MPH/50KPH weighing in at around 1.8-9 Kgs (4LBS) so you need to take care where, when
and how you use it, as uncontrolled it could cause someone serious damage.

But saying that it has been a fabulous experience working with Andre to achieve this
amazing car, something I had never imagined I would be ever doing. I also hope you
guys/girls can have as much fun with it as I have. Now printing one in CPE 100 Hg that will
survive the Hot summers as well, and it will give me the pair Ferrari and Vanwall racing
versions.
