Wizard X220HV Upgrades

thingiverse

I decided to upgrade my Wizard X220HV drone by adding custom parts I designed. Several problems with the original product had me wanting to make some changes:\r\n1) The tail piece that came with the drone was not up to par, so I created several new styles that improve VTX antenna mounting and allow for better performance with RX antennas made from coffee stirrers. Additionally, I was able to fit a MATEK H-style tail light and buzzer onto the quad.\r\n2) The original VTX placement was problematic due to excessive heat generation directly underneath the battery, which caused interference. To resolve this issue, I relocated the VTX beneath the drone and designed air ducts that bring prop wash down to cool it significantly. Moreover, relocating the bottom carbon fiber plate created space for a FrSky X4RSB RX, utilizing extra PWM channels for a video switcher, front servo to control camera TILT angle, and PWM to the H-tail. I also managed to fit in an LED controller. The custom camera tilt is necessary as this drone is not used for racing purposes; instead, it's paired with a foxeer camera and a FLIR camera (a separate mount for the Tau2 core might be uploaded later).\r\n3) The front servo mount consists of two pieces requiring a metal connecting rod to assemble. It functions well.\r\n4) To enable GPS functionality on my drone, I removed the Bluetooth module and built a strap mount that allows me to connect the GPS to the battery strap. Unfortunately, there are no I2C ports available on the Wizard FC, precluding magnetometer usage.
