Eachine Wizard X220 CAD Model Design

Project: Eachine Wizard X220 OpenVSP / CAD Model

I need a simplified but dimensionally representative Eachine Wizard X220 quadcopter model for OpenVSP / VSPAERO aerodynamic analysis as part of an MSc dissertation.

The model should include:
- Main body/frame
- Four arms
- Four motors
- Propellers or simplified rotor discs
- Battery/electronics volume where aerodynamically relevant

The main reference dimension is approximately 220 mm diagonal motor-to-motor wheelbase.

The priority is accurate:
- Overall dimensions
- Motor positions
- Arm geometry
- Central body geometry
- Propeller diameter
- Frontal/projected area

Small details such as screws, wires and antennas are not required.

OpenVSP Requirements

Preferred output is native OpenVSP geometry suitable for:
- VSPAERO
- Rotor-off / bare-airframe analysis
- Rotor-on modelling
- Different wind speeds
- Different angles of attack

Deliverables
- .vsp3 OpenVSP file
- STEP/CAD file if available
- STL export
- Main dimensions used
- Brief list of modelling assumptions/simplifications

The model will be compared with wind-tunnel measurements of:

Lift, Drag, Side Force, Pitching Moment, Rolling Moment and Yawing Moment.

Manufacturing-level detail is not required. The main aim is a reliable aerodynamic model of the Wizard X220 for OpenVSP/VSPAERO analysis.
