12Z Radio System FAQ

I still cannot figure out how to have Dual rates and exponential at the same time. I only see one place to set this up, but every time I try to put in expo, it erases my D/R settings. How do I lock in the dual rates and then set up expo?

If you go to the AFR (d/r) menu and select the channel desired, you can set up exponential and dual rate. First set up the AFR 100% travel. Set Rate A and Rate B for the amount and direction of throw, at your normal 100% rate. Normally, you'd not adjust anything there.

If you want exponential at 100% rates, you will need to go to "Mode" at the center of your page. It defaults to "Linear". Change it to Exp1, which is the normal expo curve for most models. Set Exp A and Exp B to the amount of expo curve you wish.

To set up a dual rate, now go to the "D/R" screen by scrolling down to the second page. Select D/R 1 and turn it on. Select which switch you wish to have it operate. After you select the switch, select its 'on posi'. Now move the switch to the D/R 1 position. Set Rate A and Rate B to the amount of D/R you wish for that function. If you want that rate to also have an expo curve, then set the amount of expo. If you leave expo at 0% but change the % of the rates, you have a linear dual rate. If your original rate had no expo, you can leave the rates at 100% and change EXP A and EXP B and have an expo on/off. You can have a lower rate with expo.

Remember to add expo to a rate, just change the linear button to EXP 1.
