1、 Basic knowledge

The PIka is a 5 inch propeller drone. This is not a toy. If done incorrectly, it can harm the human body.
The PIka is using the Betaflight firmware flight control, and the introduction of Betaflight can be referred to the second part.
The way to type the rudder, as shown below：

The order and direction of the motor:

The manufacturer recommends a 4s 1500mAh battery flight , but can also fly with the 4s (1300mAh- 1500mAh).
PIka does not recommend flying in crowded places to avoid hurting people.
if you want to feel FPV (first person vision), please flying with video glasses.

2、 Install Betaflight
