George, Where do you get that belly mount VOR antenna? Does it perform other functions, glide slope etc?

I recently shared this technic with a buddy that's wiring a Lightning. He really liked it. Geez Bob, not only do you have pictures of everything, they're easy to find on your web site :o) Thanks for teaching me so much about wiring airplanes. It's spilling over into other areas of my life. I recently wired a small 80x80 computer fan to my kegerator to help circulate cold air around my beer keg! Temps dropped from 40F to 30F overnight. Nice cold beer on tap. Also, I recently installed a fuel pump kill switch antitheft device in my F150. Got the wiring diagram online, bought a relay at Advanced Auto and went to work on the bench wiring up the harness with tools I'd bought from B&C and technics I'd learned from you. Installed without problem and works like a charm. I would never have even attempted these small projects in the past. I just love this hobby! Rodney in Tennessee DO NOT ARCHIVE >From: "Robert L.

Jim: If you are using the VOR for secondary navigation/VFR than it will be fine. If you plan on IFR flight and using the VOR to fly airways and approaches (VOR/LOC/ILS) than consider bagging the wing tip NAV antenna. The wing tip NAV antenna works but that is a relevant term. The inside wing tip antenna is not going to work as well as an external one EVER. The external antenna is hands down better. I assume you are doing this for drag reasons? Well an external VOR antenna at 200 mph cost you no more than 1/2 MPH. That is it. Also is you use fiberglass element antenna (white) it blends well with fuselage. My RV-4 was mostly white and antenna was on belly under horz stab was white. You'll never noticed it on the ground. STAY A WAY FROM THE WING TIP COM antenna, they are terrible. Since most of us are using GPS the VOR antenna is not critical but COMM is key to safety. It's up to you and you can always add an external antenna. I'm building a RV-7 and had a RV-4. HERE are some things to recommend a pair of standard Cat Whisker VOR antenna: Drag? Only 0.50 mph max at 200 mph Racing? Removable in a minute (*depending how u mount) Mount? Belly under tail or top of Vert Stab. *Here is a pic of the belly mount on my RV-4 http://img239.imageshack.us/img239/4826/temp28st.jpg Here is another builder's Vert stab mount (RV-9A) http://www.n2prise.org/Photo2/DSCL0268.JPG *I like the belly mount, shorter coax run, remove antenna in a minute. Two screws, secure coax with safety wire and stuff back in fuselage leaving a piece of safety wire out to retrieve the coax later & tape over wire & hole speed tape.

For the jumper from the + side of the contactor on the relay, to the COM tab, can I use something as low as an 18 or 20 AWG wire for this, I'm not sure of the current flow through this. Based on other posts on the subject, there's only about .1A on the line from the contactor ground tab through to the breaker and switch, so I should be able to go to a much smaller wire here.
