I have recently made a plane and the tail is heavier so how do i make the nose heavy?<br><br>Ans. Usually when the engine is installed the plane balances, but if the tail is still heavier you can put non-hardening clay or some coins to make it heavier.<br><br><br>Q. I have made a control line aircraft with wings made of single sheet of balsa wood, but as it is only a sheet of balsa it is weak so how do I make it strong?Joe.<br><br>Ans. You can mix french chalkpowder with automotive paint and apply it with your fingers or with a peice of wood (as it is too thick to use a brush) and then sand it lightly till it becomes smooth, and then you can put a coat of automotive paint + thinner to dilute it and paint with brush. <br><br>Now your wing is strong!<br><br><br>Q. Hi i am santosh i don&#39;t want to buy the plane from the net, so is there any place where i can buy it from india?<br><br>Ans. You are in luck! I happen to live in India so I know there is a large airplane shop called India hobby center in kolkata which is large. I am sure you will find the plane you want there.<br><br><br>Q. My plane isn&#39;t flying. It is a chuck glider and when i throw it into the air it falls nose down.<br><br>Ans. It is a weight problem. Don&#39;t worry, it is common and it can be solved easily! There is too much weight on the nose. Just remove the weight from the nose or add some in the tail until it balances on the C.G (center of gravity), a point located on the wing usually on one-third of it. To check this, all you have to do is to hold the plane with your fingers under the C.G point and it should balance. Add and remove weight untill it does so. The C.G point is ususally given in the plan.<br><br><br>Q.can somebody please tell me why hanger 9 dosen&#39;thave good balsa wood? packman<br><br>Ans. I don&#39;t know, I have not seen it, try www.solarbo.com I don&#39;t order from the internet, so you will have to risk buying, and finding that it is bad too,<u><b><font color="#ff0000">This site nor its creater, or writer isresponsible for any loss or damage of any sort.</font></b></u><hr size="1"><br/>]]></description></item><item><title>A few r/c terms</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/A+few+r%2Fc+terms</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/A+few+r%2Fc+terms</guid><pubDate>Wed, 18 Apr 2007 05:57:36 CDT</pubDate><description><![CDATA[Hi<br><br>These r/c terms might be useful. While reading about specific models you may come across some words that you don&rsquo;t understand, so see if you can get those here.<br><br><b>3D</b> <br><br>Term describing a type of flight pattern, which is characterized by the performance of very specialized aerobatic. maneuvers below the model&#39;s normal stall speed. Examples include torque rolls, &#39;walk in the park&#39;, harriers, hangers, etc. <br><br>For helicopters: combining two or more maneuvers into one maneuver. Examples: rolling circle, inverted backwards loop. <br> <br><b>3F</b> <br>Slang abbreviation for flip flop flying. Similar to 3D, but without the finesse. <br>The shape of the wing when looking at its profile. Usually a raindrop type shape. <br>For helis: The rotor disk is the effective wing, and airfoil refers to the shape of the blades. <br> <br><b>Angle of attack</b> <br>The angle that the wing penetrates the air. As the angle of attack increases so does lift, up to a point. <br> <br><b>Articulated Rotor</b> <br>Itis a rotor head which allows the blades to flap, drag and feather. <br> <br><b>Aspect ratio</b> <br>The ratio of the wingspan to the wing&#39;s chord (depth). For sailplanes this number will be larger than sport planes, which will generally be larger than a &quot;jet&quot; style aircraft. <br> <br><b>Autorotation</b> <br>The ability of a rotary wing aircraft to land safely without engine power. This maneuver uses the stored energy in the rotor blades to produce lift at the end of decent, allowing the model to land safely. <br> <br><b>Axis</b> <br>The line around which a body rotates. <br><br><br><br><br><br><hr size="1"><br/>]]></description></item><item><title>Important tips</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/Important+tips</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/Important+tips</guid><pubDate>Wed, 18 Apr 2007 05:56:33 CDT</pubDate><description><![CDATA[Hi<br>These are tips to make a good plane.<br><br><br><b>Balancing the aircraft</b><br><br>Balncing is very important in order to make your plane fly. If the tail of the plane is heavier than the nose the plane will stall.and if the nose is heavier the plane will fall.but if you hold the plane from the CG (centere of gravity usually located under the wings) point and the plane is properly balanced the plane will fly smoothly.<br><br><br><b>The dihederal brace</b><br><br>It is also important to give an accurate dihederal brace. the peice called the dihederal brace should be cemented to the wings very firmly. an inaccurate dihederal brace would result in an immbalanced flight. But some planes dont need a dihederal brace so you needn&#39;t worry for those planes.<br><br><br><b>Shaping the aerofoil</b><br><br>In some plane you only get a long peice of balsa wood for the wings. In those type of plane you have to sand the wing in an aerofoil shape. for a flat bottom wing the bottom surface of the wing should be left flat and on the top of the wing draw two lines lengthwise with a pencil, so that the wing is divided into three equal parts. make the trailing edge very thin and sand so that when you place a level object across the wing the object lies flat from the line near the leading edge to the trailing edge. Then round off the leading edge leaving a perfect aerofoil shape. <br><br><b>Pre-flight tests</b><br> <br>These steps are to be taken on all types of model planes. <br><br>1)Check the balancing<br>2)Throw it without powering it by any meansand see that it flies level and comes back to ground smoothly<br>3)Match all its dimensions with the plan<br><br>This is for R/c planes <br>1)Check the controls and see if they are ok<br>2)Take off<br><br><hr size="1"><br/>]]></description></item><item><title>interesting activities</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/interesting+activities</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/interesting+activities</guid><pubDate>Wed, 18 Apr 2007 04:07:45 CDT</pubDate><description><![CDATA[Hi<br><br>Don&#39;t you get bored, not flying and no plane to make.

After tuning the engine choke the engine by placing one of your fingers on the air intake and then place the other finger of the other hand on the propeller and turn. Then attach the starter on the engine (some dont need a starter) and flick the propeller hard for about 10-20 times and the engine should start. If the engine stops in a short time after starting turn in the compression setting screw and flick hard. This will take out any excess fuel in the engine or the commpression may be too high so turn out the compession setting screw and start. If the engine misfires or runs roughly, turn in the commpression setting screw till it runs evenly, If the sound is damped then turn the screw back.<br><br>And now your engine should run properly! <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><i>Note:In india the engine is stared like this i don&#39;t know if it wors in engines of other countries though mostly all are same.

If the thrust (ie. speed) is increased so that it is greater than the drag, the plane will go up</u></div>  <div>  <u>&bull;Similarly, if the amount of lift drops below the weight of the airplane, the plane will descend.</u> <u>By increasing the lift, the </u><a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/pilot.htm" rel="nofollow" target="_blank">pilot</a><u> can make the airplane climb. </u></div>  <div>  </div>  <div>  </div>  <h3>  Drag</h3>  <div>  <div>  <u>Drag is an aerodynamic force that resists the motion of an object moving through a fluid (air and water are both fluids). </u>If you stick your hand out of a <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/category-automotive.htm" rel="nofollow" target="_blank">car</a> window while moving, you will experience a very simple demonstration of this effect. The amount of drag that your hand creates depends on a few factors, such as the size of your hand, the speed of the car and the density of the air. If you were to slow down, you would notice that the drag on your hand would decrease. We see another example of drag reduction when we watch downhill skiers in the Olympics. You&#39;ll notice that, whenever they get the chance, they will squeeze down into a tight crouch. By making themselves &quot;smaller,&quot; they decrease the drag they create, which allows them to move faster down the hill. <br></div>  <div>  If you&#39;ve ever wondered why, after takeoff, a passenger jet always retracts its landing gear into the body of the airplane, the answer is to reduce drag. Just like the downhill skier, the pilot wants to make the aircraft as small as possible to reduce drag. The amount of drag produced by the landing gear of a jet is so great that, at cruising speeds, the gear would be ripped right off of the plane. </div>  <div>  </div></div>  <div>  Fluid</div><br><div>  A principal concept in aerodynamics is the idea that <b><u>air is a fluid</u></b>. Like all gases, air flows and behaves in a similar manner to water and other liquids. Even though air, water and pancake syrup may seem like very different substances, they all conform to the same set of mathematical relationships. In fact, basic aerodynamic tests are sometimes performed underwater. Another important concept is the fact that <u><b>lift </b><b>can exist only in the presence of a moving fluid</b>. </u>This is also true for drag. <u>It doesn&#39;t matter if the object is stationary and the fluid is moving, or if the fluid is still and the object is moving through it. What really matters is the <b>relative difference </b><b>in speeds between the object and the fluid</b>. </u></div>  <div>  <br>Consequently, neither lift nor drag can be created in <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/category.htm?cat=Space" rel="nofollow" target="_blank">space</a> (where there is no fluid). This explains why spacecraft don&#39;t have wings unless the spaceship spends at least some of its time in air. The <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/space-shuttle.htm" rel="nofollow" target="_blank">space shuttle</a> is a good example of a spacecraft that spends most of its time in space, where there is no air that can be used to create lift. However, when the shuttle re-enters the earth&#39;s atmosphere, its stubby wings produce enough lift to allow the shuttle to glide to a graceful landing. </div>  <div>  </div>  <h3>  Imperfect ways of creating lift</h3>  <div>  </div>  <div>  If you read any college-level aerodynamics textbook, you will find plenty of mathematical methods for calculating lift. Unfortunately, none of these explanations are particularly satisfying unless you have a Ph.D. in mathematics. Two of the most popular explanations today are the <b>Longer Path explanation</b> (also known as the <b>Bernoulli</b> or <b>equal transit time</b> explanation) and the <b>Newtonian explanation</b> (also known as the <b>momentum </b><b>transfer</b> or <b>air deflection</b> explanation). While many versions of these explanations are fundamentally flawed, they can still contribute to an intuitive understanding of how lift is created </div>  <div>  </div>  <h3>  Longer path explaination</h3>  <h3>  </h3>  <div>  The Longer Path explanation holds that the top surface of a wing is more curved than the bottom surface. Air particles that approach the leading edge of the wing must travel either over or under the wing. Let&#39;s assume that two nearby particles split up at the leading edge, and then come back together at the trailing edge of the wing. Since the particle traveling over the top goes a longer distance in the same amount of time, it must be traveling faster. </div>  <div>   <br></div>  <div>  Bernoulli&#39;s equation, a fundamental of fluid dynamics, states that as the speed of a fluid flow increases, its pressure decreases.The Longer Path explanation deduces that this faster moving air develops a lower pressure on the top surface, while the slower moving air maintains a higher pressure on the bottom surface. This pressure difference essentially &quot;sucks&quot; the wing upward </div>  <div>  </div>  <div>  Why is it not entirely correct?<br>There are several flaws in this theory, although this is a very common explanation found in high school textbooks and even encyclopedias: </div>  <div>  <br>The assumption that the two air particles described above rejoin each other at the trailing edge of the wing is groundless. In fact, these two air particles have no &quot;knowledge&quot; of each other&#39;s presence at all, and there is no logical reason why these particles should end up at the rear of the wing at the same moment in time. </div>  <div>  <br>For many types of wings, the top surface is longer than the bottom. However, many wings are symmetric (shaped identically on the top and bottom surfaces). This explanation also predicts that planes should not be able to fly upside down, although we know that many planes have this ability. </div>  <div>  <br>Why is it not entirely wrong?<br>The Longer Path explanation is correct in more than one way. First, the air on the top surface of the wing actually does move faster than the air on the bottom -- in fact, it is moving faster than the speed required for the top and bottom air particles to reunite, as many people suggest. Second, the overall pressure on the top of a lift-producing wing is lower than that on the bottom of the wing, and it is this net pressure difference that creates the lifting force. </div>  <div>  </div>  <div>  </div>  <h3>  Air deflection explaination</h3>  <div>  <div>  <u>In the late 1600s, Isaac Newton theorized that air molecules behave like individual particles, and that the air hitting the bottom surface of a wing behaves like shotgun pellets bouncing off a metal plate. Each individual particle bounces off the bottom surface of the wing and is deflected downward. As the particles strike the bottom surface of the wing, they impart some of their momentum to the wing, thus incrementally nudging the wing upward with every molecular impact</u>. </div>  <div>  <br>Why is it not entirely correct?<br>The Newtonian explanation provides a pretty intuitive picture of how the wing turns the air flowing past it, with a couple of exceptions: </div>  <div>  <br>The top surface of the wing is left completely out of the picture. The top surface of a wing contributes greatly to turning the fluid flow. When only the bottom surface of the wing is considered, the resulting lift calculations are very inaccurate. </div>  <div>  <br>Almost a hundred years after Newton&#39;s theory of ship hulls, a man named <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/framed.htm?parent=airplane.htm&url=http://www.nadn.navy.mil/Users/math/meh/euler.html" rel="nofollow" target="_blank">Leonhard Euler</a> noticed that fluid moving toward an object will actually deflect before it even hits the surface, so it doesn&#39;t get a chance to bounce off the surface at all. It seemed that air did not behave like individual shotgun pellets after all. Instead, air molecules interact and influence each other in a way that is difficult to predict using simplified methods. This influence also extends far beyond the air immediately surrounding the wing. </div>  <div>  <br>Why is it not entirely wrong?<br>While a pure Newtonian explanation does not produce accurate estimates of lift values in normal flight conditions (for example, a passenger jet&#39;s flight), it predicts lift for certain flight regimes very well. For <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/hypersonic-plane.htm" rel="nofollow" target="_blank">hypersonic flight</a> conditions (speeds exceeding five times the speed of sound), the Newtonian theory holds true. At high speeds and very low air densities, air molecules behave much more like the pellets that Newton spoke of. The space shuttle operates under these conditions during its <a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://travel.howstuffworks.com/space-shuttle12.htm" rel="nofollow" target="_blank">re-entry phase</a>. </div>  <div>  <br>Unlike the Longer Path explanation, the Newtonian approach predicts that the air is deflected downward as it passes the wing. While this may not be due to molecules bouncing off the bottom of the wing, the air is certainly deflected downward, resulting in a phenomenon called <b>downwash</b>. </div>  <div>  </div>  <div>  <b>Pressure Variations Caused By Turning a Moving Fluid</b><br> </div>  <div>  <div>  <div>  Lift is a force on a wing (or any other solid object) immersed in a moving fluid, and it acts perpendicular to the flow of the fluid. (Drag is the same thing, but acts parallel to the direction of the fluid flow). The net force is created by pressure differences brought about by variations in speed of the air at all points around the wing. These velocity variations are caused by the disruption and turning of the air flowing past the wing. The measured pressure distribution on a typical wing looks like the following diagram: </div>  <div>  </div>  <h3>  <b>The way lift is created</b></h3>  <h3>  </h3>  <div>  <b>A.</b> Air approaching the top surface of the wing is compressed into the air above it as it moves upward. Then, as the top surface curves downward and away from the airstream, a low-pressure area is developed and the air above is pulled downward toward the back of the wing. </div>  <div>   <br><b>B.</b> Air approaching the bottom surface of the wing is slowed, compressed and redirected in a downward path. As the air nears the rear of the wing, its speed and pressure gradually match that of the air coming over the top. The overall pressure effects encountered on the bottom of the wing are generally less pronounced than those on the top of the wing. </div>  <div>   <br><b>C.</b> Lift component </div>  <div>   <br><b>D.</b> Net force </div>  <div>   <br><b>E.</b> Drag component </div>  <div>  <br>When you sum up all the pressures acting on the wing (all the way around), you end up with a net force on the wing. A portion of this lift goes into lifting the wing (<b>lift component</b>), and the rest goes into slowing the wing down (<b>drag component</b>). As the amount of airflow turned by a given wing is increased, the speed and pressure differences between the top and bottom surfaces become more pronounced, and this increases the lift. There are many ways to increase the lift of a wing, such as increasing the angle of attack or increasing the speed of the airflow. Discussing the methods are beyond the scope of this site.</div>  <div>  </div>  <div>  </div></div></div></div>  <div>  </div>  <div>  </div>  <div>  </div><hr size="1"><br/>]]></description></item><item><title>beginners guide</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/beginners+guide</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/beginners+guide</guid><pubDate>Wed, 18 Apr 2007 03:56:36 CDT</pubDate><description><![CDATA[HI<br>Dont know where to start?

Or is yor plane not looking good?Many problems like this can rise from nowhere at all! But all you have to do is, read whatever is below and most, if not all, your questions will be answered!<br><br>If you are a beginner then cover your plane with monokote or ultrakote they look very good! Even expeirienced flyers can cover their planes with monokote/ultrakote They are also very easy to cover!<br>But in some places like India, they are very expensive, so we have found out other ways of covering planes easily, (just like the proverb &#39;need is the mother of invention&#39;). I guess you would be waiting to know what is it, well i guess it isn&#39;t right to keep you waiting in suspence, so here read it! <br><br>Here choose the type of covering you want to put on your plane which is most conveinient to get in your area<br>1)Use the silver foil you see in gift wrappings, And apply fevicol SR Rubber adhisive on one side.<br><br>2) This is the best! Use the <b>glow sign vinyl plastic </b>sheeting to cover your plane. It is available in quiet a few colours and has adhisive on one side. It is also as good as monokote/ultrakote<br><br>3)To cover the wing ask for the lamination film that is 24&quot; wide and 40 micron thickness. This is very good for the wing as it has incredible strength and the best is heat activated to stick and shrink<br><br>To learn how to cover with monokote <u><a class="external" href="http://aeromodlerswhoareyoung.wetpaint.comhttp://www.monokote.com/monoinst1.html" rel="nofollow" target="_blank">click here</a> </u>(this also applies to other materials discussed here).<br><hr size="1"><br/>]]></description></item><item><title>Tuning your engine</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/Tuning+your+engine</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/Tuning+your+engine</guid><pubDate>Tue, 12 Dec 2006 07:44:45 CST</pubDate><description><![CDATA[Hi<br> <br><div class="O">  <div>&bull;Tuning the engine, or setting the mixture, is a very important part of helping your engine have a long and trouble free life. There are some terms you will come across that can be somewhat confusing. For instance, you have a 2 stroke Engine but you are told to run it at a four stroke. Sounds silly? Well this is just a term that is used to indicate how rich to set the mixture. All will be explained! </div>  <div>    <div class="O">  <div>&bull;Start the engine with the throttle fully open (if you have a control line engine then this doesn&#39;t apply because they don&#39;t have a throttle) and listen to the sound. This does take a little practise to understand the different sounds it will make. If the mixture is nice and rich (too much fuel being allowed in) then it won&#39;t rev very fast, the exhaust will have lots of smoke and will sound somewhat rough. Just to make sure it is running rich, open the needle valve a little more and the revs should drop a bit. If they drop and the engine still sounds rough then it is now running at what we call a <b>rich four stroke</b>, so-called because it sounds like it is only firing every second time the propellor goes around. </div>  <div>   <div class="O">  <div>&bull;Now slowly start winding the needle in (towards the closed position). What you are doing is making the hole that the fuel comes out of in the carby smaller so restricting the rate that fuel will be drawn into the engine. This is known as leaning out the mixture. Do it slowly because some engines have very sensitive needles and a small adjustment can make a big difference to the mixture. You&#39;ll soon notice that the revs start to rise but the engine still sounds rough. Eventually, as you continue winding the needle in, you&#39;ll hear a new sound starting to come from the exhaust. </div>  <div>&bull;This sound is a much cleaner and higher pitched sound than it had before. At this point, leave the needle valve where it is and just listen. What you should now be hearing is the engine changing from the rich &quot;four stroke&quot; sound to the clean &quot;two stroke&quot; and then back to the &quot;four stroke&quot;. Adjusting the mixture to a little leaner (turning in) will make it run most of the time in a two stroke and just occasionally making the &quot;four stroke&quot; sound. A little leaner still and the &quot;four stroke &quot; sound will disappear. The engine is now running at a <b>rich two stroke</b>. It still won&#39;t be at maximum revs but it will sound smooth. </div>  <div>&bull;Now don&#39;t do the following unless your engine has been run in properly or it can be damaged. Very slowly lean out the mixture and listen to the sound. You will easily be able to hear the engine starting to pick up speed more and more as the mixture gets leaner. At some point you will notice that, even though you are still winding the needle in, the revs aren&#39;t getting higher or are even starting to drop. The engine is now starting to run lean and this is bad. The temperature of the engine will rise very quickly to the point where nasty things can happen to the piston or liner. </div>  <div>&bull;When you reach the point where the revs are at a maximum (without going too lean) you should then wind the needle slowly out about 2-3 clicks until you can hear the revs start to decrease. This is the leanest mixture you should allow the engine to run at when you fly because it will lean out slightly more when in the air. </div>  <div></div></div></div>  <div></div>  <div></div></div>  <div class="O">  <div></div></div></div>  <div> </div>  <div></div></div><hr size="1"><br/>]]></description></item><item><title>ring-winged plane</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/ring-winged+plane</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/ring-winged+plane</guid><pubDate>Wed, 06 Dec 2006 08:46:44 CST</pubDate><description><![CDATA[Material needed:<br><ol>  <li>card</li>  <li>white glue</li>  <li>straw</li>  <li>sicssors</li></ol>  METHOD:<br><ol>  <li>Cut a strip of card</li>  <li>Cut another strip about 1/3 ofthe first one</li>  <li>Curve them into rings and glue</li>  <li>STick both the rings on each of the two ends of the straw</li>  <li>Throw it into the air with the smaller ring in front. </li></ol><hr size="1"><br/>]]></description></item><item><title>learning to fly</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/learning+to+fly</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/learning+to+fly</guid><pubDate>Sun, 26 Nov 2006 08:24:15 CST</pubDate><description><![CDATA[Hi<br>You can learn to fly without unnecessary crashes!<br><br><h3>  First you should know how a plane flies.</h3><br>Go to <u><a href="http://aeromodlerswhoareyoung.wetpaint.com/page/How%20planes%20fly%3F" target="_top">How planes fly</a></u> page. And read the underlined text if you don&#39;t want to read all of it.<br><br><h3>  Now to choose the right plane</h3><br>Choose a plane that has it&#39;s wings mounted on top. The best choices are parkflyers, gliders, slow-fliers or Non- gliders (planes that are powered). CHOOSE THE PLANES THAT ARE ADVERTISED AS TRAINERS.  <br><br><h3>  Checking the plane.</h3><br><b>Confirm the following corrections are correct before each fly.</b><br><br><ol>  <li>  Make sure that the plane is properly balanced fro the point which the planes designer indicatesMake sure that there is no warp (ie. when you look from the back of the plane, you should see just a little bottom of the wing. If you see more bottom of the wing on, let&#39;s say right side the plane will nteng to go to the right even when you are holding the control in neutral.</li>  <li>  The wing should have something called a washout. Wash out is a dirirable warp at each wing tip.</li></ol><br><h3>  Fly in a big field at first</h3>DO NOT fly in a small and restricted space at first even if your plane is capable of doing so. Do not try to land at a restricted area. Just let it glide straight ahead  <br><h3>  </h3>  <h3>  Proper take-off</h3>  <ol>  <li>  Speed up until you feel that it can take-off</li>  <li>  Do not give too much elevator up command as it will result a stall.</li>  <li>  DO not climb steep up! It will stall and probably crash! Climb gently.</li></ol><br><h3>  Flying tips</h3>  <ol>  <li>  Do not turn when the plane is low.</li>  <li>  Practice gentle turns high in the air.</li>  <li>  Practice landing high up IN the air to get an idea of the planes stalls (fall- out -of the sky)</li>  <li>  If your plane stalls give a little down elevator and it will level out.</li>  <li>  If you want to tun do not hold the control stick, turn it and leave.</li>  <li>  Beginners planes usually have a built-in tendency to level out when you leave the control stick.</li></ol>  <h3>  </h3><br><hr size="1"><br/>]]></description></item><item><title>paper static model</title><link>http://aeromodlerswhoareyoung.wetpaint.com/page/paper+static+model</link><author>venkatarun</author><guid isPermaLink="false">http://aeromodlerswhoareyoung.wetpaint.com/page/paper+static+model</guid><pubDate>Sat, 11 Nov 2006 04:14:36 CST</pubDate><description><![CDATA[HiThis is interesting.
