(Ron Lendon) ________________________________ Message 1 _____________________________________ Time: 08:49:02 AM PST US From: "Leroy Wheeler" Subject: RE: Zenith601-List: CONTACTORS Contactors are nothing more than solenoids like on the starter of your car. The aircraft needs a continuous duty contactor if you want to have a master switch for your electrical system. This should be located near the battery. The starter contactor is placed in the battery area also so the starter cable is not "hot" all the time. It should be a contactor built for intermittent duty. Both are available from Aircraft Spruce.

Have been reading everything I can find on "contactors" ( AeroElectric, various Matronics lists, etc.). Do not understand most of it... so, my question is: Do I need to add one or more "Contactor" to my installation? I am not an EE, nor much of an electrician...just trying to understand what the Contactor might buy me. Planning an all-glass panel, if that makes any difference? Please don't throw electrical theory at me...I'm just looking for a simple explanation why I should or should not consider putting contactors on. If so, which one?

If you only have around 30 amps to control and your battery is mounted ahead of the firewall, you probably don't really need a master relay. You just have to make sure that nothing is drawing any current when your master switch or circuit breaker is off or you will will find the battery dead after sitting for a few days. If you have very much more than 30 amps or your battery is mounted behind the seats with large cables running through the cabin, you probably should use a master relay. The master relay will isolate the battery from all circuits, including the starter circuit. The starter circuit can draw hundreds of amps and has no over-current protection. If the main battery cable to the starter shorts out for any reason, the results can be very serious. This could easily happen in a crash landing. > > > List, > > Have the 3300 with FWF kit from Jab.USA.

From: "PatrickW" While fitting the fiberglass saddle between the horizontal stab and rudder of my XL, I kept thinking "there's got to be a better way"... I've looked through the archives for ideas, so I got that base covered. But I was wondering if anyone recently had done anything original with their own version of the saddle. The one I have is fairly mis-shapen, and while I could certainly make it work by using a heat gun to bend it, I can already see that the quality is going to be lousy. Has anyone totally "rolled their own" here...?
