Importance of Low Weight for Successful Model Aircraft Flight

The Critical Importance of Low Weight for Successful Model Aircraft Flight by Tim McKay

Perhaps no other factor affects the flight performance of a radio control model airplane than aircraft weight. You can demonstrate this for yourself. Take one of your favorite RC planes, one you know well, and fly it through a series of normal maneuvers. Add some additional weight to this model and fly it again. The lighter version will fly better, take off in a shorter distance, climb out quicker and handle in a more pleasing fashion.

This effect of weight on flight performance applies to all aircraft. Minor differences in weight for the same aircraft type are usually not noticeable. But if you are not paying attention to aircraft weight as you design a model aircraft or construct one from a kit or set of plans, excess weight can easily creep into your finished project.

In full size aircraft, weight is a major factor affecting flight operations. A typical jet airliner can have up to one third of its weight in fuel alone. If you take off in a Boeing 747 for a long flight, the jet transport is actually too heavy to safely land right after takeoff. The assumption is the aircraft will burn off fuel and become lighter during flight, allowing for a safe landing at a lower weight once at its destination.

With most radio control model airplanes, and especially electric powered RC models, there is no real difference between take off and landing weight. We therefore have to be careful to build the model as light as possible. Once the airplane is built, its flight weight is essentially fixed.

The question comes up as to what is an acceptable weight for an RC model plane to fly well. The answer is “it depends.” You need some method to relate total aircraft weight to the size of the model. This is usually done by making a ratio of the aircraft weight in ounces per square foot of wing area.

Wing loading, by itself, is not enough to properly predict the flight characteristics of a model airplane. Rather, wing loading is an indicator of flight performance that must be considered with other aircraft design factors.

Wing shape, airfoil and aircraft size all play a large role in determining flight performance. A trainer model plane with a Clark Y airfoil will tolerate a higher wing loading as opposed to an aerobatic model with a thin wing cross section.

A larger plane can typically handle a higher wing loading than smaller aircraft. For example, a wing with an area of 2000 square inches could support a loading of possibly 35 ounces per square foot, while a 500 square inch wing could handle perhaps 20 ounces per square foot. Note that 144 square inches equals one square foot.

Very lightweight micro sized indoor electric powered model airplanes represent a special case for wing loading and weight considerations. For truly miniature indoor RC planes, total weight is the governing statistic. The tiny electric motors and propellers produce limited thrust, and the model is essentially designed around the power plant.

Some of these micro flyers come with a flying weight of just 18 grams. There is really no point in figuring out the wing loading on a miniature model of this nature. Rather, the guiding principal is to keep everything as light as possible. Modelers who have added just a piece of tape to this genre of aircraft prevented take off due to the minor increase in weight.

We can use these aircraft performance characteristics to our advantage. When building any model airplane, and especially micro indoor flyers, keep the weight to an absolute minimum. If you are designing the model, “build in lightness” with the least amount of structure required. When building any model pay attention to the grade of balsa or other building material being used to conserve weight wherever possible.

Model aircraft weight is a critical aspect for safe flight and a predictor of performance. Few actions will more quickly and easily improve a model’s airborne characteristics than reducing the airplane’s weight. Keep this insight in mind as you design, construct and evaluate the flying performance of your RC airplane fleet.

Getting Involved with Hobby RC Airplanes

Getting Involved with Hobby RC Airplanes by Lynn Porter

Remote controlled vehicles are more than just toys especially if you buy the slightly more expensive and advanced models. It becomes more of a hobby where you can do many things such as testing your vehicle in new terrain or participating in intense races with other RC vehicles. In fact, you can take that hobby even further by getting involved with hobby RC airplanes that literally take your remote control experience to new heights. When you first got into RC cars, you should have experienced the time when you had to choose from all these different models. Expect to go through that again because there are different types of RC plane models each with their strengths and weaknesses.

Blue Ray 450 Premium Edition RC Helicopter

Some of these hobby RC airplanes are intended for experienced flyers but others are very easy for beginners to try out.

Trainer Airplanes

The trainer RC airplanes are the best choice for any beginner that wants to know basic flying tips and general fundamentals that apply to the advanced models. Their performance is best if you fly them when the weather is calm and not excessively windy. You even get a better experience if you can find a trainer that can teach you all the nice things you can do with these basic models.

Park Airplanes

Park airplanes are similar to trainer hobby RC airplanes in terms of level of experience but they are smaller in size making them more suitable for smaller areas like parks and backyards. Many of these planes are handheld so you can travel easier with them.

Foam Airplanes

Foam airplanes are best described as lightweight and durable at the same time. The foam material makes them extremely safe and crashing the RC plane should not really inflict much damage. If ever you have damaged parts, finding foam materials are easy to come by. It is even better if you get the hobby RC airplanes that are made of expanded polypropylene (EPP). You can even fly these during a rainy day as the material is waterproof. These foam hobby RC airplanes also fall in the category of electric powered airplanes because they make use of batteries rather than gasoline. This also brings down the operating and maintenance costs. If you have that artistic ability, you can try customizing or painting them as well.

Electric Powered Airplanes

Electric powered airplanes serve as a nice balance between price and performance. If the above-mentioned types of hobby RC airplanes are too basic or limited in function, a safe step ahead would be to go for any of the other electric powered airplanes that you find in stores. You won’t have to worry about things like nitro or gasoline so you can spend more time flying and replacing or recharging batteries the same way you would charge normal electronic devices.

Gas Powered Airplanes

Gas powered hobby rc airplanes are for the enthusiasts that want extra performance and realism. Only try these types of RC planes if you are very familiar in maneuvering the electric airplanes. Although they require more maintenance and skill, you get more flexibility and sophisticated controls so you can do all kinds of exhibition moves. From there, you can even go more advanced by trying to fly jet engine powered RC planes that real flight experts use.

RC Airplane Info For The Novice

Remote Controlled Airplane RC Airplane Info For The Novice by Avery Manning

Getting fellow RC plane fliers all-around, is a fantastic asset to any novice, and acquiring a community group of enthusiast to present guidance is a must have. With guide, new pilots will be cozy moving up to bigger, faster planes in no time.

RC Hobbie Cars

If you want to take pleasure in a loved ones helpful hobby with your little ones you may possibly want to commence flying electrical RC airplanes. It is a wonderful hobby that an overall household can delight in together that involves a great deal of bonding time and all kinds of clean air. A household that flies electrical RC airplanes jointly can journey all more than the nation to meet with diverse flying clubs and take pleasure in the group pursuits that these types of clubs put on all through the 12 months.

Flying an electric remote control airplane is just the identical as a standard remote management airplane. The only big difference is that an electric plane’s battery is charged by electricity as a substitute of by gasoline. The electrical energy costs up the battery pack so that when a relatives is prepared to go flying their aircraft is completely charged and all set to go.

Electrical RC planes can be flown by each young children and adults. Children normally have to be supervised by an grownup and in some destinations young children have to be of a realistic age in purchase to tackle the aircraft safely. Just mainly because they are in a position to manipulate the controls does not indicate that they have the mental wherewithal to command it safely and correctly in the air. By obtaining an grownup supervise them they not only are capable to master from watching but they are in a position to consider turns managing it on their private.

Quite usually distinctive remote management flying clubs have meets and tournaments all throughout the country. Families and flying aficionados will journey for lots of hrs just for the chance to take component in these tournaments and meet with other flying fans at the exact same time. It is a terrific bonding time and allows full households to connect with each other and converse above their preferred flying machines. Many households look ahead to these meets every single year so that they can reconnect with other families that they met on prior years to see how the youngsters have grown and what varieties of new remote manage planes have been bought.

Extra periods than not, a little one that grows up in a relatives that enjoys electrical RC airplanes turns out to be a flying buff as an adult also. It is a hobby that will get in the blood from a really youthful age and sticks with them even via to adulthood. Probabilities are that a love for flying will be passed on to their youngsters also. It is a terrific household helpful pastime that inspires little ones to dream and teaches them the worth of family members and group making though taking advantage of the excellent outdoors at the very same time.

Fly RC Airplanes, Easy Learning

Fly RC Airplanes, Easy Learning by ada faulk

Flying RC airplanes as a leisure time hobby is prevailing all over the world. If you’re thinking of learning to Fly RC Airplanes, the following will give you some fundamental information that you need to understand more about the hobby, with the added bonus of there not being an exam at the end! So get yourself comfortable, grab a drink and a snack and we’ll begin! Firstly, we should grab how it works. The letters rc stand for radio control. You’ll often see rc airplanes referred to asremote control, but technically this is an incorrect term. Radio control is the correct term because the airplane is controlled by radio signals that pass through the air from the transmitter (abbreviated to ‘tx’) to the receiver (abbreviated to ‘rx’).

Glow/Electric Powered Radio Remote Controlled RC A

The transmitter is the main box that you hold in your hands, the receiver is located inside the airplane and picks up the signals sent out from the transmitter. The radio signals are sent to the model in the same way as television and radio broadcasts are sent. Signals are generated whenever you move a stick or flick a switch on the tx, and are emitted via the antenna. All radio signals operate on a frequency, measured in megahertz (MHz*). The transmitter and receiver must be on the same frequency for them to work together, and the gadget that determines the frequency is called a crystal. Both the tx and rx need a matching crystal to function. MHz is slowly giving way to the new GHz (gigahertz) system – 2.4GHz to be exact, or ‘spread spectrum’ technology. Spread spectrum sets don’t require a crystal, as the technology is slightly different. Once the radio signal is picked up by the receiver, via the receiver antenna, it is converted into physical movement by the servos. Servos are connected to the control surfaces of the airplane by servo rods, or connecting rods, so any movement of the servo is passed directly to the control surface that it is connected to. To learn to fly RC airplanes, we should know how an rc airplane moves and turns So now you know how radio signals are sent to the airplane when you operate the transmitter, but why does the model do what it does when you move the sticks?

All controllable airplanes have control surfaces and different control surfaces do different things. The primary control surfaces are rudder, elevators and ailerons. The most basic rc airplanes will only have rudder control; the rudder is the moveable section (hinged) of the vertical stabilizer, or fin, at the rear end of the airplane. It controls the directional movement of the airplane, or yaw; when the rudder moves left, the plane turns to the left and when the rudder moves right the plane turns to the right. The elevators are the moving section (hinged) of the horizontal stabilizer, or tailplane, also at the rear of the airplane. Elevators control the pitch attitude of the airplane – whether the nose of the plane is pointing up, down or level.

When elevators are moved up, the airplane will point upwards and thus begin to climb. If the elevators are moved down, the opposite happens. When the elevators are held level, then the airplane will fly level. The ailerons are the moving sections (hinged) of each wing and are located on the trailing edge (rear) of each wing towards the outer end, or wing tip. Ailerons always come in pairs, one left and one right, and they move in opposite directions to each other. That’s to say that when one moves up, the other moves down and vice versa. Ailerons control the roll of the airplane; left aileron up / right aileron down causes the plane to roll to the left, right aileron up / left aileron down causes the airplane to roll to the right.

Ailerons used in conjunction with the elevators have the same effect as the rudder ie directional control. Practice makes perfect (almost) Once you’ve got the basic feel of flying rc airplanes, there’s one sure way to improve your flying skills – practice! But be prepared to have the odd ‘air incident’… Any rc pilot who tells you he or she has never crashed a model plane obviously hasn’t been flying one for long enough! RC planes crashes are, sadly, all part of the fun and you will damage your model at some point in time. But don’t worry! Just keep practicing as often as you can and you’ll quickly improve your skills and become much more confident with your airplane. The most important thing to do is enjoy the flying and laugh at the crashes! (so long as no-one gets hurt…) Hopefully now you know a lot more about learning to fly rc airplanes than you did before reading this part.

Now you have grab some skills, take action to practice. Better to start with RC Electric Airplanes, which are easily controlled. If you are bothered to where to get RC airplanes, well, Online Marketplace ( www. Topons. com) won’t disappoint you.
