Here are some commonly used upgrades or add-on components for drones. They are not required for use with the HoverGames drone but you may enjoy adding them. The linked items are only suggestions, and should not be considered an endorsement of any specific company.

Propellers

Original DJI propellers will be much better balanced than the propellers included with the kit, but quality comes at a price. The propellers below are very similar to the propellers that come with the HoverGames drone kit. You can also look for good quality propellers in any hobby flyer shop.

Several 3D printable models for the HoverGames drone are available on Thingiverse. Search terms such as "RDDRONE-FMUK66", "NXPhlite" or "HoverGames" should pull up most files. They are also listed below. Please also use these terms for tags if you publish anything yourself.

Also, you may also find interesting accessories by searching for "S500" or "LJI X4"

RC receiver antenna bracket

Improved landing gear T-connector

Improved landing gear parts

Note that the improved landing gear T-connector above is based on the T-connector included with this design. From this one, you should only use the part that connects the landing gear to the body of the drone.

Protective outer dome/shield

You may have to drill or cut access holes for the GPS or telemetry antenna

Propeller balancing equipment

The propellers coming with the HoverGames kit (the same as provided in the links above) can sometimes have balancing issues: one blade can be heavier than the other, which could cause unwanted vibrations. This inbalance can be removed by adding or removing weight from one of the propeller blades (sticking tape underneath the blade or by sanding it down).

To check the balance of a propeller, you can use special propeller balancing tools, which can show you whether one of the propeller blades is heavier than the other. Some people have used very basic setups, such as an iron nail. Others have used dedicated propeller balancer shafts such as the one linked below.
