Re: [ercoupe-tech] Landing Lights

Well, yes, Dan, speed is one issue, but fuel economy is another. Tandy Allen and I flew from Cape Girardeau MO to Sun N Fun two weeks ago. I was 10% faster, even though I was carrying a passenger and luggage for both of us, and Tandy was alone. At the end of each leg Tandy and I would top off our tanks and we'd put in the same amount of fuel. If I'd throttled back a bit I would have burned less fuel for the same distance with the same speed as Tandy. Drag does lots of bad things for airplanes.

You guys are too hung up on speed. I checked and it doesn't make any difference if my Ercoupe has 
landing lights or not...... either way I get 0.13 mach!

Syd,
Dang! My coupe is really slow. Now, I may know one reason. It has a landing light on each main gear. It sounds to me like we need an LED nose-bowl light, to avoid drag but endure vibration and reduce wattage required. I suppose that is unlikely to happen, though, unless it could be designed to fit more than just the Ercoupe. But, surely that could be done. Any of you manufacturers or distributors out there listening? Dave Winters

    No drag penalty if the light is in the nosebowl, but I've been
    told that the bulbs don't last long due to engine vibration.

    OK... What about the nose bowl option?

Cut into the beautifully flush riveted and custom 
        painted aluminum wings of my Ercoupe???
        That's NOT going to happen gentlemen !!!!               :-)
If I really needed that extra 8 MPH I'd be flying an RV. Dan Hall

            Skyport has a kit to install them in the wings. If I was
            installing landing lights I would go that way.

                Yes, Dan, I am confident.  I've done quite a bit of
                drag testing on Ercoupes.

                Hi Syd,
                Are you confident that number - 8 MPH for two
landing lights? The reason I ask is that I put two landing lights 
                on the main gear fairings of my Ercoupe (no shades)
                about 5 years ago and it didn't seem to make that
                big of a difference however; I didn't take before
and after measurements. I fly at night and also appreciate the visibility 
                while flying here in very busy SoCal.

                    Just a caution, Ed.  Each landing light
                    assembly will cost you about 4 mph.  Are you
                    sure you want to do this?

                    I found two old farings with landing lights in
them but I think they are too far gone to salvage. My existing farings are in great shape so one idea was to obtain a pair of cylindrical sections that house the lights and connect them to the farings already 
                    on the main gear. Does
                    anyone have a pair of these or perhaps the
entire faring-light combo in good shape that they would consider selling?
