Combustion engines for RC (Radio Controlled) vehicles, whether for cars or airplanes, are measured in either Cubic Centimeters (CC), or Cubic Inches (CI). Cubic wing loading (CWL), like typical wing loading, is an indicator for grouping airplanes by their possible flight characteristics. Wing and tail surface outlines c. Fuselage shape d. Adjustable towhook position maximizes launch angles and altitudes. Get your Stevens AeroModel Groove™ on! 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. 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. I'll be able to use a little bit smaller fuel tank also to save weight. Wing span. 64,40 m. 211 ft. Try it, it's truly useful. Goes together in as little as 2-3 hours! Lift acts perpendicular to the flightpath through the wing’s center of lift. The DG-1000 all up weight is around 1100g. In ground effect the clipped Cub lets you round out and make those “kiss the grass” landings that will stroke your ego. An 100″ plane can tolerate a much higher area wing loading than a 50″ version of the exact same plane. acting on the wing. Maximum revenue payload. ... WING LOADING: 8.35 oz./sq. Detailed info about RC Car, Friction, Radio Control and Wind up Toys. 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. 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. It just needs 1-2 hours to assemble and the DG-1000 is flying. RC Glider - DG-1000 - 2630mm wing span Fiberglass & Balsa- Electric . 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 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). Detailed info about RC car, Radio Control and Wind-up Toys. Specification : It has little to do with the aerodynamics needed to get the plane to fly at various sizes/scales in real, un-scaleable air. 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. 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). Height ft. WING CUBE LOADING: 7.1 LENGTH: 33 in. Hand-laid fiberglass fuselage increases durability and distributes weight evenly. The HQ3012 airfoil the high performance from the real DG-1000. In aircraft design there are some critical measures that will determine if your plane will fly. 875 000 lbs. Similar to the stabilizer, the wing was sanded with a sanding block to create an airfoil (semi-symmetrical in this case). fast & reliable simulation - no more guessing most comprehensive motor database ☆ over 1 million calculations per month Wing cube loading (WCL) calculator: Radio Control Related Electronic Projects. So perhaps who ever came up with cubic wing loading liked the fact that they had a number that looked something wing loading ad was related to the scale factor of the plane. Log In to reply 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. Finally, the wing was covered with one layer of glass cloth on thinned epoxy. (Designed with Lithium-Polymer (LiPo) batteries in mind but any rechargeable battery including NiCd, NiMh and LiFe batteries can be calculated if you know the voltage.) 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. 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. 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. 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 It also fly’s very well in thermals Assembling the DG-1000 is quite an easy job. 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. The higher wing loading also lets you handle higher wind conditions. ... Cubic Loading Prop Size ... RC Models Wing Dragon HL RTF Trainer Span 101cm (42") Weight: 482 g (17oz) Champ RTF Span: 22.4 in. a sport-aerobatic design or pylon racer), a low drag design is desireable. 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: If the plane will fly at high speeds (i.e. Contact Taiwan Radio Control Toy supplier-MING YANG MODEL CO., LTD. for 1/8th Scale Flux 4WD Buggy on Taiwantrade. The cubic wing loading is proportional to the square root of the scale ratio. Now also with RC unit conversions, wing and cubic wing loading and battery gravimetric energy density. Type of plane: Any plane with 'plenty of wing' makes an excellent choice for conversion since the wing loading will still be reasonable even if the plane turns out a little heavy. Those measures are the Static Margin (SM), Center of Gravity (CG), Horizontal Stabilizer Volume (VH), Vertical Stabilizer Volume (VV), and Cubic Wing Loading (CWL). Metric. In the lift equation, these factors correspond to the coefficient of lift, velocity, air density, and wing … WING SPAN 38in 965mm WING AREA 302in2 19.5dm2 DRY WEIGHT 14.4oz 408g ALL UP WEIGHT AUW 17.25oz 489g WING LOADING WL 8.23oz/ft 225.1g/dm WING CUBIC LOADING WCL 5.7 RECOMMENDED SETTINGS THROW EXPO AILERON 12°30% ELEVATOR 12°30% RUDDER 12°30% Build Skill Level : Pilot Skill Level : Enter the variables at left using the same units for all entries. 2.1.6 Wing Loading Unless otherwise stated, the minimum wing loading is 8 oz/sq ft.

With the 26 the weight will be 9 pounds and 3 ounces and the wing loading with be about 21.5oz. Personally i find cubic wing loading to be much more usefull as it tells you what your plane will fly like. Cubic wing loading is the same regardless of the size of the plane. Grouping dividing the mass of the aircraft with the power of 3/2 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). My LT-25 has a cubic wing loading of 9.4 oz./cu.ft. From the newcomer to the expert, there's something for everyone! That means, a bigger model may have greater wing loading than a smaller one. which puts it in the trainer category. 396 900 kg. Weight of the finished wing is … There is a mathematical relationship between lift, angle of attack (AOA), airspeed, altitude, and the size of the wing. Learn more about Wing Cube Loading includes free calculator. 113 000 kg. Built-up wood wing sections are expertly covered in Top Flite® MonoKote® film. 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. This avoids the problem of using just wing loading as a measure of performance, as wing loading should increase as … 249 000 lbs Dimensions. Area wing loading is most commonly used because it is widely understood. Wing loading is also more critical with smaller models. CWL is found by and can be used in comparative study at different scales. The B-2 had a top speed of 270 mph and landed at 60 mph. The SV26 will add a pound of weight. Our G480 Groove laser-cut model airplane kit defines what a no excuses small field precision aerobat should be. The cubic wing loading (CWL) factor is a size independent parameter used for grouping and comparing radio controlled (RC) planes according to flight characteristics. Maximum take-off weight. There is much discussion on wing loading, but actually cubic loading is a much better indicator of how "lightly" a plane will fly. 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. There is also a feature where you can use Cubic loading values to predict a suitable target weight based on other types of model. Each of these hurdles was cleared before we bought the plane for flying purposes. The plane with the glow engine weighed 8 pounds 3 ounces, with a wing loading of 19.03oz. Now also with RC unit conversions, wing and cubic wing loading and battery gravimetric energy density. get the best drive for your RC airplane! 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. Unfortunately, the acceptable range of area wing loading changes with the size of the plane.
