If your drone weighs 750 grams, consider installing engines that together will produce a thrust of 1.5 kg. that is, if you have installed 4 motors, 375 gr per motor). The sum of the power of the engines must produce a thrust 2 times greater than the weight of your drone. Thus, your drone will be able to fly with about 50% of effective power.
This rule is important. It allows you to ensure control of your drone at any time: when there is wind, when you perform a little more brutal or sporting maneuvers or to return to the economy if you are in limit of battery (this makes it possible not to turn the engines at full speed). If, over time, you find the steering a little too brutal, add a little weight on the drone to reach a threshold of about 70%. In our example you add about 300 gr to reach a total weight of 1050gr for a thrust of 1.5 kg (1500gr).
When building your drone, you must adapt its power to the type of use you will make. Now you know that the brand is doing something special with the series. This drone is older than the other drones compared in this list but it still deserves its place as shown in the Part 107 Test.
Indeed, it is classified in the best drones for several years already. Although many believe that products are expensive, we remind you that its price/performance ratio is by far the best on the market. It is incredibly easy to navigate, has a solid construction and is cheaper than most drones in this range currently on the market.
Its only drawback is that it can not be folded back on itself to allow its user to carry it easily in a backpack. In addition, this drone is probably the ideal solution for a buyer whose budget is a little tighter but still wants to enjoy all the power and high quality products.
The autonomy of its battery is average for the drones of this price and is amply sufficient. Its strengths are its incredible flight stability courtesy of the Gimbal 3-Axis Control as well as its 360-degree rotating camera and a host of advanced autonomous flight features. An excellent ratio functions, quality to price even if its price is high because it offers more than the majority of competing products for Part 107 Test.
The power of an engine is not everything, we must also ensure its performance. You calculate the performance by dividing the thrust in grams by the power in Watts. Good efficiency shows that the engine is of good quality because it has a low loss (which ultimately contributes to a good flight quality).
