drone flight time calculator

A higher capacity battery will be able to provide continuous electric energy for a longer time. The battery capacity is also written on the pack and is denoted in milliampere-hour (mAh). Drone flight time varies with manufacturer, model as well as your battery condition.

Or do you want to have a better idea about the drone you're about to buy? Average Current Draw (ACD) = ACD is the average current all the motors draw from the battery. The output voltage is always written on the bottom of the battery, and it remains fixed for the most part of the battery operations (it plummets greatly when the battery discharges below a certain point, see battery discharge profile chart). Do note that the battery size is measured in terms of its capacity (Ampare-hours) and not its size. First, we are going to calculate the average current the motors will be drawing from the battery to support a the total weight. Obviously this is a very simplistic calculator as it doesn’t take into account numerous factors, among them flying styling and weather conditions. We recommend: If you would like to learn more about how to achieve a longer flight time, then a good place to start is our previous blog post - efficiency vs. performance. Everyone. Finally, if you are involved in FPV racing, and are flying at high throttle levels, your flight times will degrade dramatically. Depending on how hard you are flying, FPV racing can take 3 to 4 times as much current as stable hovering does. Whenever you do any maneuvering, other than a controlled steady hover in calm air, one or more of the motors will have to spin faster, and thus pull more current. It includes the weight of the drone itself, any added accessories, and most importantly the battery. The idea is to work out how many amps your multirotor will draw to maintain a stable hover (note we are taking a stable hover to represent average flight). Lines and paragraphs break automatically. Flying in a strong cross wind can also have a huge effect on the current draw of the motors. I am the founder of FTD.

The simplest bluetooth terminal for Bluetooth-based DIY projects. If you would like to more accurately model your multirotor setup and evaluate lots more parameters, there are other, more technical web-based flight time calculators. Flight time is one of the first and most important parameters you check for before buying a drone. The more efficient the motors are, the less power it needs to lift 1 kg of weight. In some cases, it can cut the flying time by as much as 50%! Please note shipment times may take longer than normal as postal services are operating with fewer staff.

To convert from mAh to Ah, divide by 1000. Web page addresses and e-mail addresses turn into links automatically. Doing so will not only lessen its life, but it also puts your drone at risk of falling out of the sky dead if the battery suddenly plummets. I have a degree in Mechanical Engineering and have a passion for rotary and fixed-wing drones. Brushless motors have a value between 80 & 120 watts per kg and Brushed motors have a higher value of around 150 – 180 watts per kg. It makes perfect sense because drones with higher flight times give you more time in the air hence extend its usability. Are you shortlisting components for your next drone build? In respect of this, it's common practice to not discharge your LiPo batteries below 20% mAh during flight; this is known as the '80% rule'. Allowed HTML tags:
