Linear Trigger Response Defined
So what is linear trigger response? If you were to measure the voltage
supplied to the motor for each trigger position and plotted the points on a
graph, you’d be able to connect all of the points with a straight, or nearly
straight, line as shown in Figure 1 (The output voltage is represented as
a percentage of track voltage to eliminate differences between track
power supplies). You’ll notice that, after the initial voltage jump as the
trigger comes off the brake pad, the voltage progresses in a straight line
and the voltage step between each trigger position is about same (or
close enough that it’s not noticeable by the driver).

In contrast, the trigger response in Figure 2 is far from linear. As
before, the measured track voltage is represented in red, with the blue
line showing what the response would have been if it was linear.
Notice how the measured trigger response sags instead of
progressing in a straight line. The voltage changes less than 30% as
the trigger moves from position 1 to position 6, but jumps a whopping
40% as the trigger moves only 2 positions further (from position 6 to 8).

line showing what the response would have been if it was linear.

You Can Feel the Difference
1/24th scale controllers with a non-linear trigger response feel mushy
and unresponsive to trigger position in the bottom and mid range
bands and twitchy in the top bands, making 1/24th scale slot cars
difficult to drive. However, linear response controllers feel equally
responsive to trigger position across the entire range of movement.
When the voltage steps between every band are equal (or nearly
equal), 1/24th scale slot cars are much more drivable, one of the
reasons all Linear 200 1/24th scale controllers offer such superior
throttle response.
