When buying a drone, you should pay attention to the camera quality, gimbal stabilisation, GPS function, flight time, range, FPV transmission, safety functions and weight, which is regulated in particular by the EU Drone Regulation.
Here are the most important features to consider before buying a drone:
Camera
Camera resolution varies widely, going up to 8K resolution on some top models, with higher resolution usually meaning better image quality. However, sensor size is equally important, especially in low light conditions. Many drones have smaller sensors, while the frame rate (fps) should be at least 24 fps to enable smooth recording, while budget models often offer less fps.
Gimbal
Is a camera suspension that separates the drone's own movements from those of the camera in order to stabilise the image. Depending on the number of stabilised axes, a distinction is made between 1-axis, 2-axis and 3-axis gimbals. Only drones with a 3-axis gimbal deliver really sharp images without blurring.
GPS
A drone with GPS can maintain its position in the sky independently and will not be blown away even in light winds. GPS drones also enable intelligent flight modes such as Follow Me or Active Track. Automatic return to the starting position (return-to-home) is also only possible with GPS.
Flight time
Drones generally have flight times of approx. 20 to 50 minutes. It is generally advisable to buy a second battery to extend the flight time.
Range
A long range generally results in a stronger and more stable signal. Obstacles such as houses or trees can impair the connection quality. Drones with a high maximum range therefore have an advantage, as signal interruptions or image interference are less likely.
FPV
Almost all drones with a camera can transmit the drone's live image to your smartphone in real time. From the drone's perspective, this first-person view (FPV) is very helpful when filming and taking photos.
Safety function
Most GPS drones have a return-to-home (RTH) function that allows you to return to the starting position at the touch of a button. In addition, many models return automatically when the battery is low or the signal between the drone and remote control is interrupted.
Weight
Weight plays a particularly important role in the EU drone regulation. Drones are categorised into risk classes and are subject to various rules accordingly.
