> Chris, my elevator moves immediately and linearly with any trim motor initiation. We probably have the same (linear actuator) motors and mine runs
> stop-to-stop in about 10 seconds. If your total travel time is significantly more than that, you may have some binding somewhere. 
> 
> Velocity has an updated, thicker pitch spring. I like it better than the original (2003) but the above movement was not affected by the change.
> 
> That being said, it is almost too sensitive at cruise speeds. I have a device (not yet installed) which can be used to adjust the speed of linear actuators. 
> It is a Firgelli FA-SC1. I am waiting to see if I can accomplish the same thing with the adjustment on the TruTrak automatic pitch box before I install the Firgelli 
> unit. 
> 
> Just my 2 cents, but the factory linear actuator had a lot of slop, or in-out play. I disassembled it, figured out it was at the rear of the motor itself, and fabricated a tiny
> teflon "pill" to act as a bushing at the back of the motor shaft. I initially measured my total trim run time, then trial-and-error shaved the pill to the proper size.
> At first there was binding and the trim time went up to about 13 seconds. After about 4 shavings, I got it right. Almost all of the play was gone, and the run time 
> was right where it should be. It's been fine for 190 hrs now.
> 
> Good luck.
