Step 5: Adding Weights

The ideal amount of nose weight for this plane is 20 grams. This can be achieved byglueing 4 nickels and 2 pennies in 2 stacks, as shown in photos 1 and 2. If you don't have my currency, or prefer to use less valuable objects as weighting, then just find an object that weighs 20 grams and divide it in half, or find two equal sized objects that weigh the same and add up to 20 grams. A kitchen scale (electronic or mechanical) is handy to have here. Glue them about half an inch from the front of the plane, as shown in photo 3.

Once again, because I don't know the size of the plane you are building, I cannot tell you how much weight it will require to balance it. I can, however, tell you a method that will make finding the amount of weight your plane requires quite easy. I call it the "Finger Axis" technique. How to do it:

Place your 2 index fingers on both ends of the main wing, 2/3 of the way down, as shown in photo 4.
Lift the plane in the air with your 2 fingers, but don't increase pressure with you fingers, just press gently, to allow the plane to swing on your fingers freely.

Of course, if you haven't added weight, the plane's tail is just going to hang down the first time you lift it. This is the point where you keep on taping on more and more weight, testing the plane for balance as you tape more on, until you get the proper balance. Look at photos 3,4, and 5 for reference. Make sure you tape equal size weights to either side of the fuselage. You can choose different things as objects for weight, but make sure they aren't too large, so as to cause drag on the fuselage in flight.

Note: The farther the distance the weight is positioned from the front of the main wing, the less weight is needed for proper balance.
Use this as an advantage for adding less weight and a guide for the positioning of the weight.

Once the weights are positioned, glue them on with decent sized blobs of hot glue to keep them in place.

<p>and where should I place main wings(3inches*15inches) on fuselage of 15 inches?</p>
<p>what dimension of horizontal stabilizer should I take for main wings dimension(in inches) of 3*15?</p>
Can i make hand gliders with the help of balsar wood

<p>I want to make 5 ft to 6ft glider with help of thormacol or cardboard Pls wirght down <strong>dimensions</strong></p>
<p>I want to make a glider of max-3 feet.</p><p>Can I make it with Styrofoam?</p><p>How to shape Airfoil?</p><p>Please can you give me the ratios and suggest it's size.</p><p>IT'S A SCHOOL COMPETITION ON 11 JULY!!!</p><p>Please help me.</p><p>With Regards,</p><p>pk2014</p>
<p>i think it dnt wrk</p>
How do you make that
My wing dimensions are 24*120 cm square <br>My horizontal stabilizer dimensions are 16* 36 cm square <br> <br>Could you please tell me if the following distances are correct? <br>1st distance: <br>The distance from the front of the fuselage to the front of the main wing: 24 cm <br>2nd distance: <br>The distance from the back of the wing to the front of the horizontal stabilizer: 48 cm
Do you have a video for the launcher? I can't really get the idea of it
It's so COOL.Thank you i'm going to promote this glider to my friends. <br>
No problem
Did it fly ? If yes, what was the maximum flight time it has achieved ? <br>Thanks.
Yes. I didn't measure the time, but it should stay up for a long time, depending on how accurately you build and balance the plane.
I see that you have canadian currency. Can i use american money?
Yes that will be fine, You just have to find the right balance by taping on the weights and using the &quot;finger axis&quot; technique, and then glue the weights on when you find the right balance.
Very good and complete. I don't know if you said it, but <a href="http://www.google.com.ar/imgres?imgurl=http://2.imimg.com/data2/AA/LP/MY-116610/sunpac-plastic-corrugated-sheets-250x250.jpg&imgrefurl=http://trade.indiamart.com/details.mp%3Foffer%3D1411093162&usg=__1Yt25svWqmqTf5ZslG_Os0VbOA8=&h=250&w=250&sz=12&hl=es&start=4&sig2=3FIPv-_H3pT9SNwPK0juhg&zoom=1&tbnid=cMeu2RXgpjFszM:&tbnh=111&tbnw=111&ei=8YUnTs_fOYvAtgfe59C7Cg&prev=/search%3Fq%3Dplastic%2Bcorrugated%2Bsheets%26um%3D1%26hl%3Des%26sa%3DN%26biw%3D1280%26bih%3D737%26tbm%3Disch&um=1&itbs=1">plastic cardboard sheets</a> are also good for this.
Thank you. Yes, plastic cardboard would make quite a strong wing/fuselage and make less glueing necessary. It will also waterproof the plane. Thanks for the suggestion.
