An overview of suggested sources for replacement parts.
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.
An overview of commonly upgraded parts or possible add-ons to the HoverGames drone kit.
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.
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.
