3. BUILDING STEPS (HIGH-LEVEL)
1. Design & CAD modeling – Map out weight distribution, center of gravity, and airflow.
2. Frame fabrication – Cut and weld frame to spec, ensuring symmetry and strength.
3. Engine & prop installation – Mount engines with vibration dampers, align props.
4. Fuel system integration – Route lines securely, test flow and safety valves.
5. Electronics setup – Install flight controller, sensors, battery backup for controls.
6. Testing & calibration – Ground tests for RPM sync, control response, and vibration.
7. Flight trials – Begin tethered, then untethered low-altitude tests, logging data.

4. FEASIBILITY & WHY IT’S A GREAT IDEA
Fuel efficiency & endurance: Gasoline offers higher energy density than batteries, extending flight time.
Mechanical simplicity: Gas engines are robust, field-repairable, and less dependent on high-voltage electronics.
Rural & Off-grid Use: Ideal for delivering supplies to remote areas where electrical recharging is impractical.
Cargo + Crew Versatility: Enables pilot-led missions with critical cargo (e.g., emergency supplies, tools, or rescue equipment).
Lower Costs vs. eVTOLs: Less reliance on costly lithium battery packs or complex electric motors.
