Especially for foam based classes, traction changes over the course of the race as the compound fades. We can't manually adjust the Dual Rate every few minutes to make up for the change.

If a Radio maker made a function that allowed the expo to change over the course of a race. With the ability to change the curvature as well of the expo.

Example:
Eight minute race goes from 60% to 70%. With the major increase/ramp happening around the 5 minute mark.

EDIT: Meant Dual Rate NOT Expo.

While were at it, how about a radio that can be calibrated to reflect spot on temps and more sensor mounting options?

This is where a programmable thumb wheel would be great. I miss having one. All these digital controls are a PITA to adjust while you are racing.

Changed first post to reflect Dual Rate as thats what I meant.

The Airtronics MT4 has a fancy lever that can be programed for many features, little dual rate bump.... & much more.

Something you don't have to worry about hitting/switching/clicking during a race. With a ramp up over time versus a button, you get the change gradually versus one second it has so much and the next it has (possibly) too much in the middle of a race.
