We all know that the usual trim setup used in the RV's and others is very touchy.
Early in building my RV-8 I built and installed a 9 volt power supply intending to power the headsets with it.
Foolish boy, that doesn't work.
Since the 9 volts was already there I tried it on the trim motor, leaving the trim indicator supply at 14 volts.
Everything has been working fine with the trim just running slower, a good thing.
I realize that most people will not want to bother installing a separate 9 volt supply but it does work.
For those interested the shack 5 amp regulator has a schematic and parts list on the back of the package.
Contact me off-line for my trim schematic. It is in autocad format.

There was some discussion about trim speed control
here on the List some years back. The discussion
prompted (or grew out of) these two postings to
the website . . .
