Based on the experience of most people with RAC elevator trim servos I installed a RAC SPD-1 speed controller on the trim circuit in my RV-3B. My installation is a bit custom and may have different travel rates due to mechanical linkage differences than the newer RVs. When I powered it up I found that with the speed controller dialed up to its fastest setting it takes 15 seconds for the trim to go from neutral to either full up or full down, and 29 seconds for full up to full down. I understand you don't want it too sensitive in cruise, but this seems a bit slow to me.
I'd like to know how many guys installed the SPD-1 versus not, and if anyone has timed the travel of their systems please post the results for us all to compare.
Thanks!
