This thing is based on Micro TBS Dicovery from @Islemunda. The difference is that while the original is suitable for the Hubsan X4 electronics, this was changed to receive a more powerful setup with brushless motors and FPV.

Below are the parts needed to build it, but you can adapt and change anything you want.

Don't worry about the domain "outro.site" it's my click counter, just like goo.gl or bit.ly. It will redirect you to Banggood.

►Screws: http://outro.site/a7ba316479/

You will need also a voltage regulator because it's a 2S drone and the FPV is 5V, so...

►Voltage regulator (option 1, fixed to 5V): http://outro.site/52aa516478/
►Voltage regulator (option 2, variable): http://outro.site/74a2216477/

... and some small M2 screws in different sizes (0,8cm to 1,5cm)

You can choose any option of KV for the motors. The higher motor KV, the higher battery C-Rate. Mine was 5400KV.

It will fly with 2" props, and in this case considere using a higher motor KV like the 7000KV, but definetly flies better with the 3" props.

You can also build the original version from @Islemunda based on Hubsan X4 electronics

Have fun!

Will publish a video later showing the building proccess.
