Yes. You want the dual rates/differentials (D/R&EXPO) set to control the throws. For dual rates, I usually have the switches down for low rates and up for high rates. Just my preference. This is done from the DX6i TX. It's the 2nd or 3rd option. I forgot which one.

Each control surface has a switch assigned to it (and they are labeled on the dx6i). Default is 100%, say you want to control the throws on the rudder. Scroll down to rudder and then move the rudder dual rate switch to your desired position (up or down) and adjust the throw from 100% to whatever you want. Now when you flip the swith the other way, you'll have 100% throw, when you flip it back, you'll have dual rates.

This applies to bothways (up and down, left and right). Sometimes you will throw more one way than the other. You can adjust this by going to travel adjustment.

Manual has a lot of this info in detail
