In a previous article, I examined the features and assembly process of the Vortex 150 race quad. This time around, I'll get this little beast in the air and see how it performs.
The Vortex's flight controller has three default flight modes: Angle, Acro, and Horiz. You can select any of these modes during flight with a 3-position switch on your transmitter. Angle mode limits the quad's maximum pitch and roll angles and provides self-leveling when the controls are neutralized. While this is the easiest and most forgiving flight mode, the angle limits rule out any aerobatics.
Acro mode is the same thing that many flyers call Rate mode. It provides no self-leveling features or angle limits. Acro is definitely the most challenging mode to fly. Yet, it also provides the most precise control of the quad. It's like the difference between driving a car with an automatic transmission (Angle mode) and one with a manual transmission (Acro mode). It takes practice to get the feel of it, but the results are worth it.
Horiz mode is a hybrid of Angle and Acro modes. During normal flying, it behaves like Angle mode. When you input large control movements, however, the bank limits disappear and it responds as if in Acro mode. You get the safety net of self-leveling, along with the ability to perform flips and other aerobatics. If you intend to eventually master Acro mode, Horiz is a great way to transition away from Angle mode.
