A little splash on the outside may be ok, but Electronics Hates Water ! Drones have openings for necessary cooling ventilation. If water gets inside, there will probably be short circuits that destroy it. If that happens, remove the battery immediately and dry the insides very thoroughly in a...

Ando & Jackson have the basic info. Your drone's SD card must be: 1) Within its maximum GB capacity rating, 2) Fast enough to record from the drones camera, 3) Correctly formatted. (Usually FAT32.) Your drone manual, or the manufacturers website, will give these specifications. 4) And stop...

I confirm you can use any capacity Li-Ion battery that is the correct voltage. (I am an electronic technician.) For some quads there are various capacity batteries available, but from experience they are not always the capacity claimed ! (You can check battery capacity when charging through a...

Many thanks for this, but it's in German. (If anyone wants English info: https://www.dry-fluids.com/dryfluid-gear-lube-1.html) And very expensive at about £17 for 20ml. (I can get a pack of 100 new gear shafts for less than that !) Please can anyone recommend something good but cheaper ?

I had assumed that any drone's "Follow Me" mode worked by simply homing in on the controller signal. Are there different methods ?

I am a drone beginner, but I know a little about electronics. I am going to suggest: 1) Make sure the drone is dead level when you switch it on, as its gyro may be self calibrating itself on its initial orientation. (But this just a guess.) 2) Tether the drone by attaching a few meters of...

I have an Eachine E58 - can I use a better (generic ?) controller, or does each drone only work with its own controller ?
