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.

The brakes don't seem to hold very well if I rev. up to, say 1200 or so, and I remembered reading somewhere about seasoning the brakes. I think I need to do that before I try a real run-up to 1700 - 1800 RPM, otherwise, it will be very hard to hold the plane with the brakes. Can some one tell me how to do that? Something about braking while taxiing? How much, how fast, etc.? Thanks, -- Tom Sargent ________________________________ Message 3 _____________________________________ Time: 10:34:03 PM PST US From: Vanremog@aol.com Subject: Re: RV-List: Slowing down the trim PWM circuit is the proper way to do this without lowering motor torque, not a voltage regulator. Van's has proven servo controllers. -GV In a message dated 3/13/2010 12:24:04 P.M.
