Exactly. I made sure my throttle servo was centered and then I centered my carb. The arm on the carb has a screw and you can move the arm where you need it. There is a fair bit of extra room as when I was setting my end point I can close the throttle and keep going till the rod starts to bind. It has enough force that you can see the rod bend. The th-cut feature is just a set amount of extra travel to the throttle linkage. Works very well. Once you get used to the radio it gets much easier. The programing once you learn the system is not a problem. One hint I learned, if the radio does not program how it says in the manual then look into if you have it set on the right program. I tried to set up my th-cut and it wouldn't work. I tried by the book about 3 times and could get no extra movement. I started looking else where and found I had it set to a heli mode for that setting. Not sure how I did that but after setting it up in airplane mode the th-cut works just like in the book. Keep us posted.
