Payload & Fuel Configuration

Cargo payload 25 lb

0 lb (ferry)55 lb max

External fuel tanks / Ferry SETS PAYLOAD = 0

Immediately sets cargo to 0 and allows fuel above internal limit, up to full useful load (displaced payload → fuel).

Breguet: R = (V/c_t)·(L/D)·ln(W_i/W_f). Default cruise 100 mph (≈87 kt); reserve 10 min. Efficiency varies linearly with speed (87 kt → 200 mph). Altitude: K scaled +12% per 10,000 ft from sea level. Simplified model — not high-fidelity. Disclaimer: conceptual tool; actual performance will differ.

Mission: −reserve fuel, −5% F₀ VTOL takeoff, cruise out with cargo, drop payload, cruise home empty, keep 5% F₀ for vertical landing (10% total VTOL). Same cruise speed both legs; empty return L/D +10% (same SFC). VTOL = 10% of F₀ (5%+5%), not in Breguet cruise.

Breguet: R = (V/c_t)·(L/D)·ln(W_i/W_f). W_f = empty + payload. Lower cargo → more fuel → longer range. External tanks / ferry sets payload to 0 and puts displaced weight into fuel. At 87 kt (100 mph): baseline efficiency; at 200 mph: improved SFC, reduced L/D (linear). Published max range 240 mi is a company / Part 108 target. Conceptual tool only.
