Shiloh, I think you 100% right on the Jr.'s, I think they make the best servo on the market for the past few years. My 5925 Hitec's are very smooth but the JR digi is even smoother.
Harry: You can reprogram the center point on the servos to where ever it seems to center best at and then reset all the linkage. I have never used mine either as of yet. I have an Airplane buddy that uses all Hitec gear and he programmed mine when I installed them.. The new Hitec radio has a finer trim adjustment now that they say helps center much better than the old Lynx 3d.
I have a Hitec lynx 3d with spectra and have never had any trouble with that ugly thing for 3 years now. But. I have layed it to rest for the new Futaba 3PK.
