The RC plane shown above is hovering in that position. And that’s about the least impressive thing it can do. This is the power of Collective Pitch Thrust Vectoring… on a plane.
So what exactly is Collective Pitch Thrust Vectoring anyway? Put simply, it’s like strapping a helicopter rotor to the front of a plane. The basic mechanism behind this is called a Swashplate, which allows for thrust vectoring, meaning the propeller blades can actually change their pitch cyclically, while still spinning at high speeds! This is what allows helicopters to do crazy tricks like barrel rolls.
A normal … Read the rest
