Three flight modes are configured by the Vortex Wizard, and are mapped by default to
channel 5 of the R/C Tx.
This mode is the preferred mode for the more advanced mini-quad pilot.
In many ways it is the simplest mode, but also the hardest mode to learn.
In Acro mode, the accelerometer part of the IMU is not used, only the Gyro.
Because of this, the quad will not self-level, explaining the steep learning curve
for this mode.
To learn this mode, it is recommended to start flying the quad FPV, in Level
mode, get some altitude, and switch into Acro mode.
Landings in Acro mode can be a bit challenging for the beginner, so switching to
Level mode before landing is a reasonable way to deal with this.
Acro mode is the ideal mode to have fun with flips and rolls.
Angle mode is the easiest to learn. When the sticks are centered, the flight
controller is always working to level the quad.
The deviation of the Roll/Pitch controls from neutral defines the angle of the
quad in flight.
Not a great mode for racing, but definitely the mode to use for the maiden flight.
