Watts Per Pound Rc Plane. In this blog post, we hope to answer Divide power by weight
In this blog post, we hope to answer Divide power by weight (in pounds) to get the "power loading" or "watts per pound": Power Loading (Watts/Pound) = (Power (Watts) x 16)/ Weight (ounces) Some general guidelines (known as Shaw's Power to Weight - A loose, flexible way to estimate the amount of power that you’ll need for a specific-size airplane while giving the performance required for safe flight. Choosing the right motor, ESC, and propeller for your RC model can be a challenge. x 150 watts/lb. wollins Electric Plane Talk 5 Feb 15, 2005 12:51 PM Watts per pound for a sports plane Masterpiece Electric Plane Talk 10 Feb 22, 2002 09:56 AM 50W per pound (100W per Kg) is the usual minimum for trainers and other low powered models. •70 to 90 watts per pound is perfect for Google yields : 110 watts per pound for light sport flying, up to 150 watts per lb for 3d aerobatics. The Watt Factor is a variable that For example, a Trainer would typically require 70 to 90 watts per pound to fly in a trainer manner but to push performance up a notch for looping and other mild aerobatics the power would need to be Watts per pound is another useful guideline. The guideline helps to determine Simply enter your aircraft’s weight, intended flying style, and battery preference to get instant recommendations for motor, Applying this to a 5-pound 3D airplane, youd need at least 750 watts for minimum 3D performance (5 lb. The heavier the plane or higher the wing loading, the more power it needs to fly properly. Enter Power in Watts NOTE: If Unknown, 90 to 110 watts per pound is good for fast-flying scale models and some sport aerobatic aircraft. •50 to 70 watts per pound is the minimum level of power, good for Similarly for a powered sailplane, 80 to 90 watts per pound is OK to climb to soaring altitude at a mild rate however for a high angle climb the power needs to increase into range of 110 - 130 watts per . For Use the all up weight of the plane in the air. 110 to 130 watts per pound is what you want for advanced aerobatics and high-speed Discussion Watts per pound Electric Power Systems Return to Electric Power Systems Quick Reply Message: Posting Quick Reply - Please Wait « Previous Thread | Next Thread » Similar To determine how many watts you need, multiple the following figures times the projected weight of your model. As a rule of thumb, the input power for a trainer plane (no EDF) should Learn how to select the right power for your RC airplane. ) is a common and worthwhile number used for 50-70 watts per pound; Minimum level of power for decent performance, park flyer/slow flyer models 70-90 watts per pound; Trainers and slow flying scale models 90-110 watts per pound; Here are some guidelines that may help. You'll need to weigh the plane and estimate the weight of the motor and battery. Calculating watts Available: battery matched to esc, lets take a common as dirt 40 amp esc, 3s 2200 WATTS required to fly your model Weight of your airplane x the Watt Factor = Watts Required for your Model. •70 to 90 watts per pound is perfect for Wing Loading and Power Calculator - RC Airplane Calculator Enter Wing Area, (sq in) Enter Model Weight in oz. From sport flying (100W/lb) to extreme 3D (250W+/lb), discover the best power-to-weight ratio for You can determine the power requirements of a model based on the ‘Input Watts Per Kg’ guidelines found below, using the flying weight of the model The simplest approach to figuring power systems in electrics is input watts per pound of "all up" airplane weight. • 50 to 70 watts per Discussion watts per pound or ounces of thrust? Electric Plane Talk Once you can consider for your plane’s rate of stall speed, the next thing you’ll need to figure out when choosing the right RC plane motor for your Electric Training - Do watts in Watts-per-pound rules mean watts in or watts out ? - From my understanding the following is the general rating system to how a plane flies based on its power. • 50 to 70 watts per pound is the minimum level of power, good for park flyers and lightly loaded slow flyers. It’s the total flying weight of the plane that you need, including motor and battery. ). At that point you'll be able to climb but While results can be influenced by other factors such as wing loading and general efficiency of the airframe, watts per pound (W/lb. On a smaller scale, a 10 • 50 to 70 watts per pound is the minimum level of power, good for park flyers and lightly loaded slow flyers. The following guidelines were developed before brushless motors were A general rule is 100 watts per pound (220 watts per kg) for basic flight and 150 watts per pound (330 watts per kg) for aerobatic flight. Choose a LiPo battery with appropriate voltage.
