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.

This way you could have the speed trim and the fine trim. Does your low voltage system make it easier to trim out in cruise? ------Original Message------ From: jimbean6@verizon.net Sender: owner-rv8-list-server@matronics.com ReplyTo: rv8-list@matronics.com Subject: RV8-List: Slowing down the trim Sent: Mar 13, 2010 12:07 PM We all know that the usual trim setup used in the RV's and others is very touchy.
