Bo,
My Jeti DS16 ALWAYS responds no matter how fast/slow I pass thru the "cruise" setting. I must say it took some work getting the points set and I use 2 logical switches, one for increasing throttle and another for decreasing.
My DX9 does not have the ability but then I never pursued it thoroughly, I just deepened the ratchet to get a feel for the "cruise" position. Scott Covey uses throttle position to change his rudder D/R & Expo, check the forum
https://www.rcgroups.com/forums/show...-Thread/page41 and look for posts 605 & 608.
Apologies for the late reply, yesterday was the best flying day of the year so far and I spent the day at the field.
