I have been working on a drone that it completely modular. E.g You can buy the basic version and then upgrade it later on with things such as cameras and other modules. The GoDrone BASE is the perfect solution. It is amazing new technology because it is made out of LEGO!!! This makes it extremely durable as you can just rebuild it if you crash. It also means you can fully customize it using whatever lego you may already have. It features super powerful 8.5mm coreless motors and and a modern control board with a 3 axis gyro and a 3 axis accelerometer. It comes with everything you need to make and fly a drone.
