High performance Hunter VTail 400 quadcopter with two angled rear propellers "Plug and play" for easy solder-less assembly Frame made with rigid and lightweight G10 fiberglass Includes standard brushless motors, speed controllers and propellers Requires flight controller, battery, charger and remote (TX/RX) The Lynxmotion Hunter VTail 400 QuadCopter Kit (Base Combo Kit) is a high performance quadcopter. Unlike other 'x' (where the front of the UAV is facing between two legs) or '+' (where the front is facing one of the legs) quadcopters and Y-shaped tricopters, the VTail concept uses two angled rear propellers, merging both concepts. Many tricopter designs use a servo to angle the rear propeller to Yaw (rotate horizontally) the aircraft clockwise / counter-clockwise, and have an issue with asymmetry (only two propellers can counter-rotate while the third causes a bit of rotation). A 6-rotor tricopter solves the symmetry issue, but is more expensive as it requires three additional motors and ESCs. The MechanicsThe frame uses G10 fiberglass composite which is incredibly rigid and lightweight and offers significant price advantages over carbon fiber. The hardware is entirely metal, using lightweight aluminium standoffs, steel screws and lock nuts. The ''400'' refers to the diameter of the circle which passes through all four motors and is commonly used as a size reference for multi-rotor UAVs. ElectronicsThis kit requires a controller which is VTail compatible. The controller's function is to stabilize the quadcopter using onboard sensors (usually a multi-axis gyroscope and/or accelerometer). You can incorporate your own controller which uses a standard 30mm x 30mm or 45mm x 45mm mounting hole pattern (and includes compatibility for VTail designs). Note: Optional UAV & Drone Sticker Kitssold as a separate accessory in the VTail category. Multiple colors available.
