I got the linkage adjusted and it's a lot closer, H: 58% L: 70%. There's no sub trim. I could see that the carb opens way smoother. My throttle stick lines up when the carb is all the way open and when it's completely closed. Also found out that DX7's don't have a throttle curve adjustment in acro mode. I'm thinking I can get a few flights in today if there's no rain. I should be fine for a while without any expo for the throttle.
