Details can be found here- www.aircraftextras.com/RelaySpeedCont1.htm Regards, JT www.jtsrv8project.blogspot.com ________________________________ Message 2 _____________________________________ Time: 10:51:40 AM PST US Subject: RV8-List: Re: RV8-List Digest: 2 Msgs - 03/13/10 From: Martin Sobel There are two systems on the market that slow down the trim motor at higher air speeds. (I find this to be a problem with all of the normal installations.) Both use an airspeed sensor. One is part of a box that makes wiring the airplane simpler and the other is by TCW Technologies: www.tcwtech.com Both available from Steinair.com Martin Sobel RV-8 Wings On 3/14/10 4:59 AM, "RV8-List Digest Server" wrote: > * > > ================================================= > Online Versions of Today's List Digest Archive > ================================================= > > Today's complete RV8-List Digest can also be found in either of the > two Web Links listed below.
