The VTail frame you see here was originally made after Bledi contacted DiaLFonZo, requesting a professional platform design based on his prototypes. After many hours of design and talk, they came with this awesome flying beast.
About the Mini VTail
The Mini-VTail is a high performance mini size 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 frame uses G10 fiberglass composite which is incredibly rigid and lightweight and offers significant price advantages over carbon fibre. The hardware is entirely metal, using lightweight aluminium standoffs, steel screws and lock nuts.
The Mini-Vtail is Lynxmotion's smallest VTail frame measuring about 283mm motor to motor. This measurement is the diameter of the circle (in centimeters) which passes through all four motors and is commonly used as a size reference for multi-rotor UAVs.
The VTail design requires a controller which is VTail compatible. The controller's function is to stabilize the aircraft using onboard sensors (usually a multi-axis gyroscope and/or accelerometer). In addition to the main controller, each motor needs an electronic speed controller (ECS) ideally designed for the very fast response time needed by performance multi-rotor aircraft.
- Controller: FLIP (Multi-Wii compatible flight controller). This is one of the least expensive flight controllers on the market and uses the Arduino programming language. Onboard is an ATMega328 chip, a 3-axis accelerometer and a 3-axis gyro. All pins are pre-soldered.
- Alternately you can incorporate your own controller which uses a standard 30.5mm x 30.5mm and a 35mm x 35mm mounting hole pattern (and includes compatibility for VTail designs)
To keep costs down we are not providing printed Assembly Guides. They are provided online, so you will need to print them when you order the kits. By providing the assembly guides online we can provide more detailed and up to date information than the old hardcopy method allowed.
