acting on the wing. The wing is 70 mm wide at the root, 50 mm at the tips, and the span is 627 mm. If the plane will fly at high speeds (i.e. Wing and tail surface outlines c. Fuselage shape d. In this article we will take a more in-depth view into what these measurements mean in practical terms and how to apply them to your projects. The Clipped Wing version of the Cub is an excellent trainer because it is responsive, crisp on the controls and has a better power-to-weight ratio. 249 000 lbs Dimensions. In the lift equation, these factors correspond to the coefficient of lift, velocity, air density, and wing … Learn more about Wing Cube Loading includes free calculator. Grouping dividing the mass of the aircraft with the power of 3/2 RC Glider - DG-1000 - 2630mm wing span Fiberglass & Balsa- Electric . This much power would give you the equivalent of a plane like a Midwest Aerostar 40 or Great Planes PT-40 trainer powered with a basic ringed .40 glow engine. Adjustable towhook position maximizes launch angles and altitudes. 396 900 kg. We welcome opinions on these factors which may preclude a flight attempt, especially if empirically based (e. g. cubic wing loading comparisons or actual experience with aged glue joints while flying 1950s vintage models). Similar to the stabilizer, the wing was sanded with a sanding block to create an airfoil (semi-symmetrical in this case). The wing area and wing loading is not listed because it is more work to calculate, and also due to the fact that scale models of similar aircraft will have similar wing loadings if their spans are the same. Now also with RC unit conversions, wing and cubic wing loading and battery gravimetric energy density. From the newcomer to the expert, there's something for everyone! Weight of the finished wing is … Automatic Battery Discharger: Automatic Battery Discharger - Enhanced: Battery Monitor: Buoys - Illuminated - for Paula III: RC Switch: Servo Driver - Switched - Simple: Sound Generator - Piston Engine: Sound Generator - Jet Engine / Guns: Arming Plug for Electric Models There is much discussion on wing loading, but actually cubic loading is a much better indicator of how "lightly" a plane will fly. Goes together in as little as 2-3 hours! The HQ3012 airfoil the high performance from the real DG-1000. Maximum revenue payload. Each of these hurdles was cleared before we bought the plane for flying purposes. ... Cubic Loading Prop Size ... RC Models Wing Dragon HL RTF Trainer Span 101cm (42") Weight: 482 g (17oz) Champ RTF Span: 22.4 in. Those measures are the Static Margin (SM), Center of Gravity (CG), Horizontal Stabilizer Volume (VH), Vertical Stabilizer Volume (VV), and Cubic Wing Loading (CWL). Cubic wing loading is the same regardless of the size of the plane. The plane with the glow engine weighed 8 pounds 3 ounces, with a wing loading of 19.03oz. It also fly’s very well in thermals Assembling the DG-1000 is quite an easy job. The DG-1000 all up weight is around 1100g. There is also a feature where you can use Cubic loading values to predict a suitable target weight based on other types of model. Since Wing Area Loading (WAL) directly correlates to the size and weight of the airplane, it is not a good measure of an airplanes “flyabilty” or flying characteristics, this is where Wing Cube Loading comes in. Some basic rules of thumb may be followed when designing an easy flying trainer model according to the drawings below: One may start by choosing the desired wingspan from which all other related dimensions may Imperial. 40% airplanes have much higher wing loadings than small electrics, however, if the cubic loadings are the same they will fly very much alike. For an aircraft to be stable in pitch, its CG must be forward of the Neutral Point NP by a safety factor called the Static Margin, which is a percentage of the MAC (Mean Aerodynamic Chord). You can have two planes with the same wing loading that fly totally different if at all but cubic wing loading tells you if it will fly like a glider or an edf jet. Detailed info about RC car, Radio Control and Wind-up Toys. Specification : In ground effect the clipped Cub lets you round out and make those “kiss the grass” landings that will stroke your ego. My LT-25 has a cubic wing loading of 9.4 oz./cu.ft. Wing span. Height The Radio Control Aero Portal bringings the R/C model aircraft pilot all the news, views and infomation available in the radio control model aircraft world. A full scale Cessna 152 has a cubic loading of about 13 oz./cu.ft., which puts it at the high end of the trainer category (not surprisingly, it’s one of the most popular full scale trainers). Unfortunately, the acceptable range of area wing loading changes with the size of the plane. I'll be able to use a little bit smaller fuel tank also to save weight. ft. WING CUBE LOADING: 7.1 LENGTH: 33 in. fast & reliable simulation - no more guessing most comprehensive motor database ☆ over 1 million calculations per month Combustion engines for RC (Radio Controlled) vehicles, whether for cars or airplanes, are measured in either Cubic Centimeters (CC), or Cubic Inches (CI). Static Margin … Area wing loading is most commonly used because it is widely understood. Get your Stevens AeroModel Groove™ on! With the 26 the weight will be 9 pounds and 3 ounces and the wing loading with be about 21.5oz. W ÷ C = wing loading, where “W” is exit weight in pounds and “C” is the canopy’s surface area in square feet For example, if you have a total exit weight of 190 pounds and fly a 190-square-foot canopy, your calculated wing loading would be: This avoids the problem of using just wing loading as a measure of performance, as wing loading should increase as … Trainers: (70 to 80 watts per pound) These types of models have moderate wing loadings, with high-lift flat bottom airfoils, and spend most of their time flying at around ½ throttle. 2.1.7 Modification of Design and Construction The following aspects of reasonable fidelity to the original design are required: a. Proportions of whole design b. Cubic wing loading (CWL), like typical wing loading, is an indicator for grouping airplanes by their possible flight characteristics. Contact Taiwan Radio Control Toy supplier-MING YANG MODEL CO., LTD. for 1/8th Scale Flux 4WD Buggy on Taiwantrade. Personally i find cubic wing loading to be much more usefull as it tells you what your plane will fly like.

The cubic wing loading (CWL) factor is a size independent parameter used for grouping and comparing radio controlled (RC) planes according to flight characteristics. Finally, the wing was covered with one layer of glass cloth on thinned epoxy. Now also with RC unit conversions, wing and cubic wing loading and battery gravimetric energy density. 2.1.6 Wing Loading Unless otherwise stated, the minimum wing loading is 8 oz/sq ft. See Rules 5.6.3 and 5.9.3 for exemptions. Maximum take-off weight. It has little to do with the aerodynamics needed to get the plane to fly at various sizes/scales in real, un-scaleable air. 875 000 lbs. Metric. An 100″ plane can tolerate a much higher area wing loading than a 50″ version of the exact same plane. Wing loading is also more critical with smaller models. The SV26 will add a pound of weight. Lift acts perpendicular to the flightpath through the wing’s center of lift. There is a mathematical relationship between lift, angle of attack (AOA), airspeed, altitude, and the size of the wing. Enter the variables at left using the same units for all entries. Built-up wood wing sections are expertly covered in Top Flite® MonoKote® film. All you need to know is your wing span, wing area and all up weight (or estimated target) and it will spit out Wing loading (in g/in2 and oz/ft2), Span loading and Cubic Loading.

Hand-laid fiberglass fuselage increases durability and distributes weight evenly. a sport-aerobatic design or pylon racer), a low drag design is desireable. 42 FLY RC MAGAZINE ... Brown B-2 was designed around the 300hp, supercharged, 544-cubic-inch Menasco Super Buccaneer engine and was the second in a series of three similar racers. The concept of “Wing Cube Loading” is that by creating a formula that incorporates the square root of the wing area, that makes the formula a cubic equation. ... WING LOADING: 8.35 oz./sq. In aircraft design there are some critical measures that will determine if your plane will fly. CWL is found by and can be used in comparative study at different scales. Cubic Wing Load is also known as Wing Cube Loading (WCL) or 3D Wing Load, see 3D Wing Loading by Larry Renger To keep the required input parameter to the basic the following values are based on a simplyfied aircraft model and are only approximate numbers.
