Decide on\u00a0Motor Size\u00a0First<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>To begin with, you need to answer these 2 questions:<\/p>\n<ul style=\"font-weight: normal\">\n<li>What\u2019s your quadcopter\u2019s planned total weight ?<\/li>\n<li>What\u2019s the size of your frame?<\/li>\n<\/ul>\n<p>The total weight of the quadcopter can be your best guess, as you haven\u2019t built it yet. It should include\u00a0everything: frame, FC, PDB, wires, motors, ESC\u2019s, battery, payload (such as HD camera and gimbals), etc. Remember this is just an estimation so you can always go back and update\u00a0the number when\u00a0you have better idea which parts you are going to get.<\/p>\n<p>By knowing the size of the frame, you should know\u00a0what the maximum propeller size can be used.<\/p>\n<p>By knowing these 2 things, you can now\u00a0calculate roughly how much thrust the motors need to deliver to lift it in the air, by using propellers of limited size.<\/p>\n<p><strong>2:1 Thrust to Weight Ratio<\/strong><\/p>\n<p style=\"text-align: justify\">A general rule is that you should\u00a0<strong>AT LEAST<\/strong>\u00a0be able to provide twice as much thrust than the weight of the quad.\u00a0This is the bare minimum to ensure you have a stable copter\u00a0that is easy to control during\u00a0hovering \ud83d\ude42\u00a0If the thrust provided by the motors are too little, the quad would\u00a0not respond well to your control, it might even\u00a0have\u00a0difficulties to take off.<\/p>\n<p style=\"text-align: justify\">For example if we had\u00a0a quadcopter that weights 1kg, the total thrust generated by the motors at 100% throttle should be at least\u00a02kg, or\u00a0500g per motor (for a quadcopter).<\/p>\n<p style=\"text-align: justify\">For faster flying like drone racing, you should expect the ratio to go much higher than this. It\u2019s not uncommon to see someone build a mini quad that can achieve 8:1, even 10:1 thrust to weight ratio. The quad\u2019s performance would be much more agile and dynamic, it would accelerate much faster and corner better. But\u00a0when you have excessively high thrust to weight ratio, the quad would become very hard to control, because a little increase in throttle is enough to\u00a0\u201cshoot the quad in to orbit\u201d. \ud83d\ude42<\/p>\n<p style=\"text-align: justify\">My recommendation is, even if you only\u00a0just plan to fly the multirotor as a slow aerial photography platform, you might want to\u00a0aim at somewhere between\u00a03:1 and\u00a04:1. Not only it gives you better controllability, but also the room for adding\u00a0extra payload in the future (like heavier cameras, or maybe extra batteries to extend flight time)<\/p>\n<h4 style=\"color: #000000\"><span class=\"ez-toc-section\" id=\"Motor_Size_and_KV\"><\/span><strong>Motor Size and KV<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Brushless motors in RC is normally indicated by a 4-digit number \u2013 AABB. \u201cAA\u201d being the\u00a0<strong>stator width<\/strong>, and \u201cBB\u201d being the\u00a0<strong>stator height<\/strong>. Basically, the wider and taller the motor is, the more torque it can generate.<\/p>\n<p>KV is another important parameter, it\u2019s\u00a0the theoretical increase of motor RPM (rotation per minute) when voltage go up by 1 volt without\u00a0load. For example, when powering a 2300KV motors with a 3S LiPo battery (12.6V), the motor would spin at about\u00a028980 RPM. This is just an estimation by the way.<\/p>\n<p>But once you mounted a propeller on the motor, the RPM won\u2019t be that high due to resistance. Higher KV motors would attempt to spin the propeller faster, but lower KV motors normally generate higher torque. That\u2019s why we tend to see\u00a0larger props are paired with\u00a0low KV motors, and smaller props with\u00a0high KV motors. (You can alter the KV of a motor by reducing or increasing the number of copper wire winding in the motor!)<\/p>\n<p>It\u2019s important to find a balance between RPM and torque when choosing motor and propeller.<\/p>\n<p>By pairing\u00a0high KV motors with excessively large propellers, the motor will attempt to spin it fast like they would do with smaller props, and therefore drawing too much current and generating too much heat. Eventually it could\u00a0burn out the motor due to overheat and shorts in motor coils.<\/p>\n<p><strong><span style=\"color: #000000\">N and P<\/span><\/strong><\/p>\n<p style=\"text-align: justify\">You might sometimes see something like \u201c12N14P\u201d. The number before the letter N means the number of electromagents in stator, and the number before P means the number of permanent magnets in the motor.<\/p>\n<p style=\"text-align: justify\">Most motors have the same 12N14P configuration, some lower KV motors would have more electromagnets and permanent magnets to help increase torque more efficiently (and thus more expensive).\u00a0While it\u2019s good to know what this is, it\u2019s not an essential piece of information when picking motors.<\/p>\n<h4 style=\"color: #000000\"><span class=\"ez-toc-section\" id=\"Frame_Size_%3E_Prop_Size_%3E_Motor_Size_and_KV\"><\/span><strong>Frame Size =&gt; Prop Size =&gt; Motor Size and KV<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Most of the times by knowing frame size, we can estimate\u00a0what sort of motor we should use. This is\u00a0because frame size limits props size, and prop size limits motor size and KV. But anyway, always check motor thrust test data to verify the current draw does not exceed safety rating of the motor, when pairing\u00a0the propellers you want to run.<\/p>\n<p>This table is only a simplified example to give you some ideas and assumes you are running 4S LiPo battereies, you might see people using slightly higher or lower KV motors than this table suggests. Frame size is referring to wheelbase (aka diagonal motor to motor distance).<\/p>\n<table style=\"font-weight: normal;color: #757575\">\n<tbody>\n<tr>\n<td><strong>Frame Size<\/strong><\/td>\n<td><strong>Prop Size<\/strong><\/td>\n<td><strong>Motor Size<\/strong><\/td>\n<td><strong>KV<\/strong><\/td>\n<\/tr>\n<tr>\n<td>150mm or smaller<\/td>\n<td>3\u2033 or smaller<\/td>\n<td>\u00a01306 or smaller<\/td>\n<td>\u00a03000KV or higher<\/td>\n<\/tr>\n<tr>\n<td>180mm<\/td>\n<td>4\u2033<\/td>\n<td>\u00a01806<\/td>\n<td>\u00a02600KV<\/td>\n<\/tr>\n<tr>\n<td>210mm<\/td>\n<td>5\u2033<\/td>\n<td>\u00a02204-2206<\/td>\n<td>\u00a02300KV-2600KV<\/td>\n<\/tr>\n<tr>\n<td>250mm<\/td>\n<td>6\u2033<\/td>\n<td>\u00a02204-2208<\/td>\n<td>\u00a02000KV-2300KV<\/td>\n<\/tr>\n<tr>\n<td>350mm<\/td>\n<td>7\u2033<\/td>\n<td>\u00a02208<\/td>\n<td>\u00a01600KV<\/td>\n<\/tr>\n<tr>\n<td>450mm<\/td>\n<td>8\u2033, 9\u2033, 10\u2033<\/td>\n<td>\u00a02212 or larger<\/td>\n<td>\u00a01000KV or lower<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"color: #000000\">Voltage and Current Draw<\/p>\n<p>It\u2019s also important to understand that voltage will have a large impact on your motor and propeller choice. Your motor will try to spin much harder when a higher voltage is applied, and thus drawing a higher current.

To pick the best motor for your application, you should\u00a0consider the following factors:<\/p>\n<ul style=\"font-weight: normal;color: #000000\">\n<li>Thrust<\/li>\n<li>Current Draw<\/li>\n<li>Efficiency<\/li>\n<li>Weight \u2013 Moment of Inertia<\/li>\n<\/ul>\n<p>The decision here really depends on your preference, how you want your aircraft to perform.<\/p>\n<p>Higher thrust gives you top speed, but you also need to look at efficiency, making sure it\u2019s not using\u00a0a ridiculous amount of power that is exceed\u00a0what your hardware can support.<\/p>\n<p>Also your choice of motor and propeller\u00a0can affect your choice of batteries too. If your quad could draw a\u00a0large amount of current at full throttle, your battery\u2019s max discharge rate has to be able to keep up in order to provide the power, as well as they don\u2019t overheat and go buff (check out\u00a0<a style=\"color: #ff002a\" href=\"https:\/\/oscarliang.com\/lipo-battery-c-rating\/\" target=\"_blank\" rel=\"noopener\" class=\"broken_link\">C rating<\/a>).<\/p>\n<p>One thing that often get overlooked is motor weight, it\u2019s more important in racing drones. It doesn\u2019t only affect the total weight of your quadcopter and thrust to weight ratio, it also affects the moment of inertia of your quad. When your quad is doing flips and rolls for example, it takes some time to pick up the angular acceleration and eventually move to the desired position. If your motors are heavy, it will take the quadcopter longer to do this, and therefore feels less responsive.<\/p>\n<p>It\u2019s all about balance really, or which area you want your copter to excel at.<\/p>\n<p style=\"color: #000000\"><strong>More tips on Motor Efficiency<\/strong><\/p>\n<p>A multicopter is more efficient when it\u2019s as light as possible.\u00a0This post shows you\u00a0<a style=\"color: #ff002a\" title=\"How to choose battery for Quadcopter, Tricopter and Hexacopter\" href=\"https:\/\/oscarliang.com\/how-to-choose-battery-for-quadcopter-multicopter\/\" class=\"broken_link\">how to find the perfect balance when choosing LiPo batteries for your multicopter<\/a>.<\/p>\n<p>Battery and weight is not the only factor we need to consider when it comes to overall power efficiency. When choosing motors, apart from motor KV and thrust, we also need to look at motor efficiency.<\/p>\n<p>It\u2019s like cycling, cycle\u00a0at\u00a0lower\u00a0gear enable you\u00a0to go\u00a0faster\u00a0but it\u2019s harder\u00a0to peddle. If you are going uphill, and it\u2019s\u00a0getting steeper, you will eventually come to\u00a0a point where peddling becomes too heavy and you are getting slower although you are peddling very hard. This is where you lose efficiency.<\/p>\n<p>The same applies to\u00a0brushless motor, the higher\u00a0efficiency the better. A 70% efficient\u00a0motor produces 70% power and 30% heat. A 90% efficient motor produces 90% power and 10% heat.<\/p>\n<p>With less efficient\u00a0motors not only are you wasting a lot of energy\u00a0(and thus flight time), you also get little\u00a0thrust\u00a0on full throttle. Most importantly, because the motor runs so inefficiently, the response time suffers. It will take the motors longer\u00a0to reach desired\u00a0RPM\u00a0and this will have negative influence on\u00a0stability and responsiveness.<\/p>\n<p style=\"color: #000000\"><strong>Other Factors Manufacturers Don\u2019t Tell You<\/strong><\/p>\n<ul style=\"font-weight: normal;color: #000000\">\n<li>Response<\/li>\n<li>Temperature\u00a0(explain more in future update)<\/li>\n<li>Best props\u00a0(explain more in future update)<\/li>\n<li>Vibration\u00a0(explain more in future update)<\/li>\n<\/ul>\n<p>Response \u2013 how fast the motor can change RPM.

Although it\u2019s not always necessary, it\u2019s good practice. I personally only do this on large motors though like 2212 or bigger.

The intention is to use 2 CW motors and 2 CCW motors on a quad, so that when the motors spin, all four prop nuts lock themselves down. It really matter which one you pick as they are identical motors except the prop shaft thread. But I personally prefer to get all motors of the same threads so I don\u2019t confuse myself with the different prop nuts.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Choosing_Propellers\"><\/span><strong>Choosing\u00a0Propellers<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Propellers generate thrust by spinning and moving air.

There are propellers of different length and pitch. For example 9\u00d74.7 (sometimes 9047) propellers are 9 inch long and has a pitch of 4.7 inch. 5x3x3 (sometimes 5030\u00d73) means 3-blade 5\u2033 propeller that has a pitch of 3 inch.<\/p>\n<p>The Size of a propeller is measured from tip to tip, and it\u2019s\u00a0sometimes called diameter, as when you spin up a prop you get a circle and the diameter is the size of the prop.<\/p>\n<p>Pitch is sometimes called pitch length too,\u00a0which\u00a0can be defined as the travel distance of one single prop rotation.<\/p>\n<p>Generally, either increased propeller pitch or\u00a0diameter\u00a0will lead to higher current draw, because more air is moved (assuming\u00a0RPM is the same), and it gets harder to spin. In a nutshell, larger propeller or higher pitch length will increase your vehicle speed but\u00a0also use more power.<\/p>\n<p><a href=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller-diameter.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-24783\" src=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller-diameter.jpg\" alt=\"propeller diameter\" width=\"300\" height=\"92\" srcset=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller-diameter.jpg 300w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller-diameter-272x83.jpg 272w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><strong><span style=\"color: #000000\">Effects of Prop Size and Pitch<\/span><\/strong><\/p>\n<p style=\"text-align: justify\">When deciding on prop size, length and pitch, you need to find a good balance.<\/p>\n<p style=\"text-align: justify\">Generally a prop with lower pitch numbers can spin faster (higher RPM), the motors don\u2019t need to work as hard to spin it so it pulls less current. If you want to do acrobatics, you will need lower pitch\u00a0propellers which provide higher\u00a0acceleration and it puts less\u00a0pressure\u00a0on the power system. Lower pitch propellers will also improve stability.<\/p>\n<p style=\"text-align: justify\">A higher pitch propeller moves greater amount of air, which could create turbulence and cause more prop wash. It generates\u00a0more thrust in the expense of higher current draw, but giving you higher top speed.<\/p>\n<p style=\"text-align: justify\">A smaller prop is easier to stop and\u00a0speed up while a larger prop takes longer to change RPM due to\u00a0inertia.<\/p>\n<p style=\"color: #000000\"><strong>Material<\/strong><\/p>\n<p>Propellers can\u00a0be\u00a0made of different materials, plastic, carbon fibre, wood etc. Each type of material gives unique features, for example carbon fibre and wooden props are stiff and best known for their smooth performance, certain plastic compound are very\u00a0durable\u2026 check out\u00a0<a style=\"color: #ff002a\" href=\"https:\/\/oscarliang.com\/carbon-fibre-props-plastic-propeller\/\" target=\"_blank\" rel=\"noopener\" class=\"broken_link\">this post<\/a>\u00a0for more info.<\/p>\n<p style=\"color: #000000\"><strong>Shape<\/strong><\/p>\n<p>The shape of the propeller also plays a big part in performance. The most distinctive difference would probably be the\u00a0<a style=\"color: #ff002a\" href=\"http:\/\/intofpv.com\/t-propeller-tip-normal-bullnose-hybrid-bull-nose\" target=\"_blank\" rel=\"noopener\">tip of the props<\/a>: pointy nose, bull nose (BN) and Hybrid bullnose (HBN). Basically for propellers that are the same size and pitch, pointy tip props are the most efficient however pulls less thrust. Bullnose props can pull higher in thrust number, however they also draw a lot more current. This is due to the fact that they have a larger surface area than than the pointy tip props. And HBN props is in between the two.<\/p>\n<p><a href=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-24784\" src=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1.jpg\" alt=\"propeller\" width=\"640\" height=\"427\" srcset=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1.jpg 640w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1-300x200.jpg 300w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1-600x400.jpg 600w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1-272x181.jpg 272w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/propeller1-544x362.jpg 544w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p><strong>Number of Blades<\/strong><\/p>\n<p style=\"text-align: justify\">The most common propellers\u00a0are probably 2 blades (or dual-blade). The next up is Tri-blade which is also very popular among racers and freestylers. You can sometimes even see quad-blade and even hex-blade. Basically, the more blade a prop has, the more surface area and thus can generate more thrust. However that also leads to higher current draw and lower efficiency.<\/p>\n<p style=\"text-align: justify\"><a href=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/prpellers.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-24785\" src=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/prpellers.jpg\" alt=\"prpellers\" width=\"300\" height=\"225\" srcset=\"https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/prpellers.jpg 300w, https:\/\/blogimage.geekbuying.com\/wp-content\/uploads\/2017\/01\/prpellers-272x204.jpg 272w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p style=\"color: #000000\"><strong>Testing is Only for Reference<\/strong><\/p>\n<p>It\u2019s important to check out motor thrust tests, and see which props work better with the motors you plan to run. Same propeller can perform very differently on 2 different motors.<\/p>\n<p>Even the for props of the same size and pitch, when they are made of different material and by different manufacturers, the performance also tend to be very different. Here is an example where I\u00a0<a style=\"color: #ff002a\" title=\"Gemfan 5030 VS HQ 5030 Propellers Props For Mini Quad\" href=\"https:\/\/oscarliang.com\/gemfan-5030-hq-5030-prop\/\" class=\"broken_link\">compare the 5030 props<\/a>\u00a0of two different brands.<\/p>\n<p>However these bench tests are done in static environment, and therefore\u00a0it doesn\u2019t represent the motor\/propellers true performance in the wild \u2013 where air are moving and there are many other factors that can have some effect on it. One of the most noticeable difference between static bench test and real flight is motor thrust, which is normally 5%-10% less in real flight than in static bench test.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong>Conclusion<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify\">With a well balanced motor and propeller combination, your quadcopter should achieve great efficiency, not only improve battery life time, but also allows great user control experience.
