high altitude with dlg

any light weight ideas to "seeing" dlg at high alt ? Or do most not take them that high ? I have been flying electric and spec it out . the bright color wing helps,and has saved me a few times !

Hate to add weight, but at the price of a few grams / if thats possable / may be worth it . I like to fly up to were the thermals are stronger on those weak days .

thanks rt

rt,

I've done some spec out flights with my DLGs. This thread details some of my efforts: http://www.rcgroups.com/forums/showthread.php?t=1526411

As far as ideas of how to see it -- I live in the southwest, and our field elevation is 4200 feet. So with low humidity, that gives me very clear skies most of the time. Therefore, I don't have to fight haze as an obstacle to seeing my plane.

On the other hand, all of my planes tend to blend into the blue background of the sky at upper altitudes. For me to really get the plane up in high, I need some clouds for a backdrop. This provides me two advantages. 1.) contrast against which I can see the plane (usually just a silhouette). 2.) It gives me a physical sight reference in the sky for locating my plane when I do lose sight of it (I was flying against THAT cloud, in THAT particular puff). This is quite helpful on regaining visual contact and orientation.

I have had my Akcent up to 3106 feet, and absolutely needed the clouds to maintain contact. I also had to plan my descent so that I would continue to have a cloud backdrop until I was sufficiently low to see the plane against blue sky.

Finally, regarding colors -- Last summer I painted the bottom of the wings and stabs of my SailAire black (they were purple and orange), and the visibility increased tremendously. Against absolutely clear skies last June, I had it up to 4400 feet. I'm still trying to get to one mile -- perhaps this summer.

thanks buzzfly , I too use clouds some times as a back drop for contrast !
I was thinking of maybe a bright color mylar on out board tips , Dye or something
maybe a bit of solite ,although I,m not sure of a light weight way to stick it ?. If low temp iron on ,,,ok .

Some buds at the field thought I had my ascent to 1500 -1700' and on a 60" wing.
my eyes hurt !

maybe a light coat of fluorescent paint of tips say 4 to 7" in ? How much weight
would that be ? best guess ?

Looking to buy a Topsky 1.0 this spring . can,t wait ! BTW anyone on where to buy and at best price ,,,nervous to by foreign so skipmiller best ?

I was with Mark when he did it.

If your airplane is a typical DLG, then here is the lightest way to get a black under surface: flat black, misted on in a thin coat. I used water-based acrylics on my Taboos, and it worked a charm. With an airbrush, you can mist on a light coat, for a weight impact of just a few grams. The secret is a gentle, mist coat. It doesn't even have to completely cover to do the job.

Rattle-can paints from the hardware store could do it,too. I am told they sometimes attack the foam in the wing.

My Blasters are alternating white and black, and that works well against both cloud and clear sky. Mine have substitute tails, and I find that the white tails provide a useful flash when far away.

If you have an airplane with an open structure, use dark, transparent covering. Red, blue, orange and green have all worked for me, against both clear and cloud.

Good luck!

Yours, Greg

I was involved in several projects as a flight test engineer. Color is pretty much meaningless when the airplane is far away and very small. The human eye does not have enough resolution under those conditions. The key is contrast (and nothing provides contrast like black) and non-reflective (hence, flat black).

It took two of us to see Mark's airplane, it was so far away. Even the Sailare.

Yours, Greg

I have to agree with Greg on the flat black.

At the altitudes I've had my planes, colors just don't show up well. Greg's B3s with the black and white stripes are quite visible, although I don't know if they are better than solid black at higher ranges.

For my DLG attempts, I chose not to change the color schemes. My Akcent is cream on top, and orange on the bottom. My Gambler is translucent red and yellow.

If I were to change the colors for visibility, I would opt for solid flat black on the bottom of the wings (if going for altitude) or black and white stripes for high but not super high work.

thanks greg
My old ascent is a transparent red orange ,man it shows up well . I was thinking
fluorescent, although black may be the best ! I just tested some rust oleum spray flor- orange , I had on hand , on some old blue foam.It did not seem to attack it bad , and on topsky I assume its epoxy glass , so should be ok ,,but will test first .

Would prefer flor- red but what the hay ,,, The thing I have to get over is when spraying light it looks blotchy, rt

I like holographic stickers. When the plane is way up you can at least catch a sparkle of light so you can find the plane....may not help with orientation much, but sometimes just keeping sight of (or re-finding) the plane is a challenge....

You can find 8x10 sheets of the stuff at most craft stores like hobby lobby or Michael's

You can also find it at sporting good stores in the fishing area... it is used for decorating fishing lures so they sparkle.

The fishing lure stuff is considerably heavier due to the thick waterproof adhesive it's backed with. The craft store stuff is half the weight and thickness.

Here is another link with a picture, but I think he's over priced and it is the heavier stuff. I prefer the craft store stuff. http://www.hilaunch.com/Wing_tape.htm SCROLL TO THE BOTTOM.

The lightest spray paint is from Michae'ls called Design Masters. They have lots of colors, but no flo-orange. Its their own brand. Lots of Free Flight DLG flyers use it, along with FA1 flyers.

That stuff is HEAVY.... My stuff is lighter than standard monocoat covering.

I found what I'm using in my shop and the info was on the back!! so here you go!!

http://www.darice.com/ecom/QuickSear...ia=holographic

****All the sheets with stock number 2511-XX are the light weight stuff.

The silver and gold are the best for reflective at distance. The red and blue are pretty and can aid orientation with sparkle AND by being a dark patch on the bottom of the wing. Some guys cut 1/2 - 1 inch strips and place them on the upper leading edge of the wings too. The silver and gold are the best for that.

My Radian has a flourescent orange wing and a black wing. Over 2000 feet the orange wing is no longer visible. The black still is. I fly mostly cloudless skies.

Yeah I know the link was useless for purchase, but that was the site on the backing paper. At least now you have the official stock number. It's easy to find holographic sticker, but finding the light stuff is a crap shoot when retailers don't list much information on what they stock.

Fly high

Just tought I'd chime in here and say that usually any flouro paint is applied over a white base coat. That being the case, if you are being weight conscious, then you would be adding twice the weight.
I gotta say I like the idea of Holographic patches (or what ever) to give a glint in the sun! I'm continually taking my eye off "just for a second"
