Hey guys, It's been a few months I have this throttle and I feel if I try to be very precise about speed and move it slowly (for example when I want to land) the throttle is jerky. Instead of sliding smoothly it is sticky, not smooth, it catches. Was wondering if it is a common problem, or if there is an issue with my throttle ? I did grease it with a lithium based grease, it slides better but if going very slowly it is still sticky and not smooth. Any ideas ?
