# FunCub QuadPlane (Pixhawk)
The Fun Cub QuadPlane VTOL is a standard tailplane aircraft (the Multiplex FunCub) that has been retrofitted with a QuadCopter system.
Key information:
- Frame: Multiplex FunCub
- Flight controller: Pixhawk
Unmodified, the Fun Cub is a relatively affordable plane and relatively easy to fly. After the conversion the plane is significantly heavier and less aerodynamic. It still flies quite well but needs around 75% throttle in forward flight.
# Bill of Materials
The actual plane looks roughly like as shown in the image above (other similar models will work just fine - this is a Multiplex Fun Cub). The minimal equipment required is:
- Multiplex FunCub (or similar)
- Pixhawk or compatible
- 数字空速传感器
- 900 kV motors (e.g. Iris propulsion set - motors and ESC)
- 10" props for quad motors (10x45 or 10x47)
- 10" prop for fixed-wing motor (10×7)
- GPS module
- 4S battery
- Aluminum frame for mounting the quad motors (10x10mm square tube, 1mm wall thickness)
- TOW is ~2.3kg with a 4200mAh 4S battery
# Structure
The structure is made out of aluminum booms as shown below.
# 布线
The outputs of Pixhawk should be wired like this (orientation as seen like "sitting in the plane").
提示
The servo direction can be reversed using the PWM_MAIN_REVn parameters in the PWM_OUTPUT group of QGroundControl (cogwheel tab, last item in the left menu).
