Don't even think about trying it. That will not work unless you have some sort of switching box to only have one antenna connected to the receiver at a time. If two antennae are connected together, there will be phasing problems, and you will have a very strange set of lobes in your antenna pattern. If you use a wing tip antenna, you need to accept the fact that there might be a very small area off the other wing tip where you might not have reception. I have seen reports from several builders with wing tip antenna who reported that they had good reception off the other wing tip. I don't understand how that could be so, but I'll take their reports at face value until I can flight test my wing tip antenna. If you are navigating using VOR, or shooting an ILS approach, how often is the station of interest off one wing tip? The only case I can think of is if you want to fly a DME arc approach. I'll use my IFR GPS to navigate the arc, and use the LOC once I've turned onto final.

I purchased mine from an A&P years ago so I couldn't tell you the brand of the original, but he swore by it and it has not let me down. At one point during my testing process I had a small fuel leak in the fitting going to the fuel flow transducer. Knowing the fitting was already torqued to specs, I backed out the nut and put a very small amount on the flared tubing, re-torqued the nut to specs and no leaks since.

I think the Harbor Freight borescopes use acrylic fibers. I may be wrong about that, but it is common on inexpensive scopes like this. I would at least examine the medical device idea. Take a look at ebay for endoscope and you should see both rigid and flex scopes. A medical scope will give you the best optical performance by far, but the illuminator is a separate component and is an additional expense. It also is less portable and more complicated to use. The flexible endoscopes are great. The end articulates through 180 degrees, controlled by the handpiece, so you can see the entire area you are interested in, and the insertion tube is often four feet long. It's common for the sheath, the rubber part of the insertion tube to become damaged. This must be repaired before it can be used on a patient but would have no effect on the use you entend. Often the medical facility will decide to dispose of the scope instead of repairing it, and they end up on ebay. You also find scopes that have broken fibers which causes dark spots in the field of view. This is common and a brand new scope will often have a few. The repair of this is $4000 or so depending on the scope if it gets bad enough and you can often find a perfect scope that has been disposed of because this. If you go this route, don't purchase a scope with a cloudy field of view. There is no repair possible without completely disassembling the scope and usually replacing parts. I use a rigid scope which has limitation on what you can see, but has the advantage of fitting through 1/8 inch hole. A flex scope will require more like a 1/2 inch access hole.

Also, as illuminator i bought a single LED flashlight for a few bucks, took the lens out and made a plastic spacer to fit between the nipple on the scoop and the inside of the flash light. seems to work quite okay so far. not as bright as a real illuminator light source, but, a heck of a lot more transportable.

This helps prevent tearing up the screw head during installation / removal (especially screws that have been installed for a while).

My experience with the Sportcraft internal NAV antenna is that is works very nicely, regardless of the plane's position in regard to the VOR. It also works well with a glideslope receiver. Bob Archer, the designer of the antenna, is emphatic on NOT using two NAV antennae. Apparently all sorts of out-of-phase issues arise if two antennae are feeding the same receiver.

The Pozi drive was specifically designed not to require axial force to maintain engagement. That is the principle difference between Pozi and Phillips, and is reason I recommended Pozi as a good alternative to Torx.

As a data point , my RV is equipped with a Garmin 430 suite and fitted with a Bob Archer NAV/LOC/GS antenna in the left wingtip and the MB antenna (a tuned length of copper foil) in the right wing tip. I have not had any reception problems to date though I've never purposely positioned the aircraft in flight so the NAV antenna is completely blocked by the opposite wingtip (LOS) to the station in a purposeful effort to observe (potential) signal degradation. If such a loss did occur and I still found it desirable to navigate based upon that particular VOR, (why?) I suppose I "could" deselect the VOR (via a button on the 430) and select the GPS function and continue to navigate via the installed GI-106A CDI in much the same way. Of course that would require programming in the coordinates of the VOR station as a GPS waypoint. Such flying is possible but a bit too sophisticated for this VFR pilot. Also in my neck of the woods, VOR signal acquisition does not occur on the ground but comes alive just a few hundred feet AGL....mere seconds of time in an RV. If your anticipated mission requirements demand the very best NAV reception possible, many would argue that externally mounted antennas would probably be a better choice. For my purposes which is overwhelmingly VFR flight with occasional IFR training, the hidden wingtip mounted antennas suit me just fine. One more thing....despite occasional reports that some builders experience signal problems, I located the Comant bent whip Comm antenna almost perfectly centered and in line with the gear legs and have yet to experience any problems. I installed standard RG-58A/U coax cable throughout. More expensive coax cable is available and only you can determine if it is worth the extra cost or not.

On my Garmin (nee Apollo) SL-30 NavCom you just need to run one coax from the antenna to the radio, there is an internal splitter for the Nav/glideslope signals. The AirTech kit is for the older type wingtips, and is not necessary for the newer "sheared" tips that are currently shipping.

I used an MFJ-259B Antenna Analyzer to trim the dipole for lowest SWR in the middle of the VOR band, and the wires measure 22 inches on each side. My plane is an RV-7A slider and the feed line comes up the baggage bulkhead and forward with a loop to allow the canopy to travel. The antenna wires are just number 22 white insulated aircraft wire which go outboard and then forward using 2 suction cups on each side for support. This puts the antenna mostly above the baggage compartment, with the ends just above and behind the pilot's and co-pilot's head. It may look a little dorky, but the performance is excellent and it costs practically nothing. I intend to put some ferrite chokes at the feed point to make it perfectly horizontally polarized, but it works fine with just the center conductor of the RG-58 going to one side and the ground going to the other side. It was originally intended to be temporary, but has become somewhat permanent. Please don't laugh!

The down side to that theory is that at many controlled airports you cannot just start turning xwind 400 ft because of conflict with other controlled traffic. At many airport you cannot start a turn at 400 ft because of noise abatement procedures. I have had the experience as others here have had and it WILL take you a few seconds to grasp what the problem is and how to solve it. At 400 ft you are losing valuable time and airspeed. I can whip my RV-6 around on a dime too if I am planning on it. Not telling anyone to try it or not try it just giving an opinion that is a valuable as what you pay for it. :) Jerry do not archive ________________________________ Message 30 ____________________________________ Time: 07:00:29 PM PST US From: "John Furey" Subject: RE: RV-List: Minimum altitude to return to airport --> RV-List message posted by: "John Furey" Please be very careful. As an instructor for a specific make of aircraft we taught the "turn back" maneuver for many years. Essentially the same thing you did only it took about 1000'agl and 60~70 degrees of bank. It was pretty neat as long as it was done perfectly but it can get REAL ugly. Unfortunately an experienced instructor and his client died a couple of years ago, they had performed it successfully several times earlier that day. It was immediately removed from the training curriculum, the grief and the law suits are still ongoing.

I did some of testing on this during flight testing, and practice it once in a while. My drill is to chop throttle, wait four seconds with hands in lap, then take action. I think this is a realistic figure for the brain lag. I came up with 400 feet as the minimum altitude to even think about a 180. YMMV, but try it for yourself, and practice.
