4. More about THROTTLE AA
The PROFI CAR also has plenty of interesting facilities to offer for throttle:
v 2-point throttle curve with EXPO, or 5-point throttle curve
v Automatic Start
v TC (traction control) PROFI CAR 707 only!
v Separate throttle servo PROFI CAR 707 only!
To help you understand:
The diagram on the right shows
which servo settings are assigned
to the individual points on the
throttle-brake curve.
Between the points Initial Throttle
IT and Full Throttle FT the setting of
the throttle servo is proportional to
the position of the trigger.
At the idle setting (ID) the servo
does not move, provided that the
trigger stays within the deadband {variable: see 9.1}. As soon as the throttle trigger
moves into the working range, the throttle servo jumps to the Initial Throttle position
IT.
4.1. 2-point throttle curve with EXPO
The two-point throttle curve is generally adequate for electric-powered model cars.
With the help of the EXPO facility you can easily set up a throttle response curve
which gives you just the feeling of control you prefer.
Use the menu button A to locate the throttle curve, and the handle button
G
to
select the individual points on the curve. The advantage of this system is that you
don’t actually have to apply full throttle in order to adjust the full throttle point.
The diagram on the right shows the
correlation between the trigger move-met
and the servo travel in graphic form.
The area with the grey background is the
deadband. As long as the trigger stays within
this range, the throttle/brake servo stays at
the idle setting IDL.
Between the two points Initial Throttle IT and
Full Throttle FT the throttle curve is linear -
assuming that you have set EXPO to 0%. The
dotted lines show how EXPO affects the throttle curve
