The “QuadHawk™” is a new remote-control aircraft with the unique capability of both hovering like a helicopter and high speed “dash” flight. It represents the next evolution of the “quadcopter” philosophy unlocking significant upgrades in flight efficiency, controllability, and top end speed. This starts with a change in basic design philosophy to prioritizing drag reduction. As a result, all the electronics and structure are molded into aerodynamic shells. Current quadrotors simply power through this drag. That increases your motor, speed controller, and battery weight. It reduces flight time, maximum takeoff weight, and the amount of gear you can carry onboard. Completely streamlining the design of a conventional quadcopter fundamentally increases your flight performance!
If top end speed is your goal, you should think twice about how a conventional quadrotor works. Current quadcopters have pushed to more powerful motors and bigger batteries to enable faster speeds but most of that power is wasted on lift instead of speed. This is the “brute force” approach. It can certainly work, but we live by the motto, “Work smarter, not harder.” And that brought us to the capability of “Missile Mode Flight.” Essentially this means pitching your quadrotor over into horizontal flight. Doing so points all four motors forward allowing you to use nearly all the onboard power to generate thrust and thrust is speed.
A conventional quadrotor would not be able to sustain this as it is not generating enough lift to keep it in the air. The QuadHawk, however, uses wings to generate lift. So when it pitches over, lift is provided by the airframe, not the batteries. What’s more, by pitching over, the QuadHawk presents its low-drag airframe into the wind where conventional quadcopters are bulky flat plates catching the air and slowing it down.
The QuadHawk’s controls are augmented beyond a typical quadrotor’s by a set of servo actuators which move control surfaces. These are used for providing extra control power in a hover as well as to add control at high speeds. As a quadrotor flies faster and faster, the net thrust decreases and as a result, they begin to lose control power. But because the QuadHawk generates lift with wings, small control surfaces can be used to adjust that lift differentially to maintain control. These control surfaces actually get more responsive the faster you go. By combining a quadrotor’s variable thrust and torque with aerodynamic control surfaces, you get boosted control at all flight speeds.
We have built the QuadHawk around the highest quality, top performing, and expandable control boards on the market intended for first person video (FPV) racing. But we are not limiting you to a single control board. Inside the aircraft is a mounting plate that can accommodate any control board you want with ample internal volume to expand your capabilities with things like a camera, video downlink, GPS, etc…
These reasons make the QuadHawk design ideal for racing. We are currently testing a “boosted” version of the QuadHawk that meets or exceeds the onboard power and thrust-to-weight of today’s FPV racers. We call it the QuadFalcon. If you want an edge on the racing competition; if you want to be faster and more agile using the same onboard power; don’t just brute force the problem; work smarter, not harder. Missile mode is the answer. Support our Kickstarter where you can order your own QuadHawk or QuadFalcon racer: QuadRKT – The future of drone racing
