AutoGyro Cavalon

AutoGyro GmbH, headquartered in Hildesheim, Germany, is the world's largest gyroplane manufacturer by volume, building roughly 300 aircraft per year as of the mid-2010s and holding a commanding share of the global gyroplane market. The company produces three core civilian models that share a common rotor head, pre-rotator, and Rotax powerplant family but differ radically in cabin architecture: the open-tandem MTOsport (originally the MT-03), the enclosed-tandem Calidus, and the enclosed side-by-side Cavalon. All three are pusher-configuration autogyros with a semi-rigid teetering two-blade rotor, tractor-equivalent Rotax 912ULS (100 hp), Rotax 914 turbo (115 hp), or Rotax 915iS injected turbo (141 hp) options.

The MT-03 / MTOsport was the company's first mass-market success after AutoGyro's 2003 founding, and Wikipedia notes it became a "market leader" in the open-cockpit gyroplane segment; an MT-03 set a world gyroplane distance record of 1,263 km in Australia. The Calidus (introduced 2009) added an enclosed composite cockpit for weather protection while retaining tandem seating. The Cavalon, introduced 2011, broke from tradition with a wide side-by-side cabin resembling a small helicopter or car — the most "mainstream GA" presentation of any gyroplane on the market and a favorite of pilots transitioning from fixed-wing.

In the US, the family is sold through AutoGyro USA (the factory's North American arm) in Experimental Amateur-Built and Experimental Light Sport Aircraft (ELSA) kit and professionally-built forms. The Cavalon in particular is popular for police surveillance, pipeline/powerline patrol, and private cross-country recreation. Related European competitor: magni-gyro (Italy).

The Cavalon is the heaviest and most luxurious variant; the MTOsport is the lightest and cheapest entry point. Performance numbers in the frontmatter reflect the Cavalon with Rotax 914 turbo, the most common US configuration.

Gyroplane performance diverges sharply from fixed-wing intuition. The Cavalon cruises at only 85–90 KTAS regardless of power setting because the rotor imposes a hard aerodynamic speed limit near 100 KIAS (Vne) — pushing harder just burns fuel without gaining speed. Fuel burn at cruise is a modest 5.0–5.5 GPH on the Rotax 912ULS/914, giving roughly 4+ hour endurance on the Cavalon's 23 US gal usable fuel and a still-air range near 400 NM.

Unlike helicopters, gyroplanes cannot hover, but they can fly at 20 kt or less into a headwind with full control authority, making them exceptional observation platforms. The Cavalon's rate of climb is solid at ~980 fpm solo, but degrades meaningfully at gross weight and altitude — the Rotax 914's turbo normalization recovers most of that at density altitude, and the 915iS option further improves hot-and-high numbers.

Takeoff rolls are remarkably short (300–400 ft with pre-rotator spin-up) and landing ground rolls are essentially zero — gyroplanes can perform "zero roll" landings at idle power into any headwind above ~10 kt. Service ceiling is limited by rotor tip Mach and engine breathing more than aerodynamics; 13,000 ft is realistic with the 914 turbo.

Crosswind capability is exceptional: gyroplanes can land in 30+ kt direct crosswinds because the rotor disk simply tilts, and there is no fixed wing to weathervane. This is one of the family's headline selling points.

The Cavalon's 529 lb useful load and 156 lb full-fuel weight mean the aircraft comfortably carries two 180 lb adults plus 170 lb of baggage/options at full fuel — a genuine two-up cross-country machine, unlike many lighter gyroplanes.

• Full fuel (23 gal / 138 lb), solo: 390 lb available for pilot + baggage. Max endurance ~4.2 hours, still-air range ~360 NM at 85 KTAS.
• Full fuel, two 180 lb adults: 29 lb of baggage. Range unchanged at ~360 NM.
• Two 200 lb adults, full fuel: Overweight by ~9 lb; reduce to ~21 gal (~325 NM range).
• Max payload (two 200 lb adults + 129 lb baggage): Fuel reduces to 0, untenable — realistic mission is 15 gal / 240 NM.
• Optional 31.7 gal long-range tank: Adds ~$2k cost and ~50 lb full fuel weight; extends solo range to ~500 NM with no useful-load penalty empty.
• Calidus comparison: 408 lb useful load, 23 gal fuel, tandem — 100 lb less payload than Cavalon but similar range.
• MTOsport comparison: 452 lb useful load but only 9–18 gal fuel standard; a local-flying and training gyroplane, not a cross-country tool.

In practice, Cavalon owners treat it as a two-seat, 300-NM-leg touring gyro — comfortable, weather-protected, and remarkably capable for its category. For compact tandem or open-cockpit configurations, see magni-gyro M-16/M-24 equivalents.

• Flight training (5): Gyroplanes require a separate rotorcraft-gyroplane rating, so the Cavalon is not a general-purpose trainer — but AutoGyro USA's flight school network uses Cavalons and MTOsports as primary gyroplane trainers. Scores moderate as a specialty trainer, poor as an entry to fixed-wing or helicopter ratings.
• Backcountry (7): Short takeoff, near-zero landing roll, huge crosswind tolerance, and benign slow-flight make the Cavalon a surprise backcountry contender. Ground clearance and tire size are the limiting factors versus a Carbon Cub or Husky.
• Business travel (2): 85 KTAS cruise and no IFR capability disqualify it from serious travel.
• Aerobatics (2): Gyroplanes cannot perform negative-G or inverted maneuvers; rotor unloading is catastrophic. Low scores universally.
• Cross-country (5): The Cavalon is the family's cross-country champion — enclosed cabin, side-by-side seating, 23 gal fuel, 4+ hour endurance. Still slow, but comfortable enough for 400-NM legs. The MTOsport and Calidus score lower due to tandem seating and (MTOsport) weather exposure.
• Cargo hauling (2): Useful load is respectable at ~525 lb but baggage volume is tiny.
• Local fun flying (10): This is the Cavalon's headline mission. Short legs, low/slow sightseeing, wide panoramic view, operates from any paved or turf field, weather-tolerant, and novel enough to draw a crowd wherever it lands.
• Surveying / patrol (9): Gyroplanes dominate European pipeline/powerline patrol and police surveillance work. The Cavalon Pro has factory FLIR, moving map, and searchlight provisions. Low stall, low fuel burn, and long endurance beat both fixed-wing and helicopter options on cost-per-hour.

Stock Cavalon panels typically ship with a Dynon SkyView or Garmin G3X Touch single-screen EFIS, Garmin GTR 200 comm, Garmin GTX 335 ADS-B out transponder, and a simple autopilot-ready config (though autopilots are rare in gyroplanes). Cavalon Pro patrol packages add a second SkyView screen, FLIR Star SAFIRE or similar gimbaled camera interface, moving-map tactical overlay, and downlink radios.

Unlike certified GA, the experimental category means panel upgrades are cheap and unrestricted — owners routinely swap in dual Dynon HDX or Garmin G3X setups for under $15k. IFR certification is theoretically possible in some European jurisdictions but is not offered in the US, and gyroplanes are categorically VFR-only in practice.

Because the family is sold as Experimental in the US, there are no STCs — modifications are builder/owner discretion. Common factory and aftermarket options:

• Rotax 915iS upgrade ($18–25k): 141 hp injected turbo, meaningful hot/high improvement, FADEC-like Electronic Control Unit, widely considered the "best" Cavalon engine.
• Long-range fuel tanks: Cavalon optional 120 L (31.7 gal) tank extends range to ~500 NM.
• Glass cabin heat (~$1,500): Essential for winter operations; Calidus and Cavalon come heater-ready.
• Rotor pre-rotator upgrades: Newer hydraulic pre-rotators reach 250+ rpm, reducing takeoff roll below 200 ft.
• FLIR/EO gimbal mount (Cavalon Pro only, $80–200k for the camera itself): factory patrol option.
• Float / amphib conversions: Not offered by AutoGyro; a few experimental one-offs exist in Europe.
• Ballistic parachute (Magnum or GRS): ~$8k; fits all three variants, increasingly common in Europe.

AutoGyro USA (Bensalem, PA and satellite service centers) is the primary US support channel, with a growing network of factory-authorized service centers. Parts availability is good from Germany but lead times of 2–6 weeks for non-stock items are common.

• Annual condition inspection: $1,500–3,000 at an authorized shop; owner-performed on Experimental Amateur-Built.
• Rotax 914 maintenance: Standard Rotax intervals — 100 hr inspection, 25 hr oil change, 5-year rubber replacement ($2–4k).
• Rotor blades: Composite carbon blades, ~2,000 hr life, ~$12k/set replacement.
• Rotor head bearings: Inspection at 600 hr, replacement typically at 1,200–1,800 hr ($3–5k).
• Tires/brakes: Small and cheap; 3-wheel gear is simple.
• Typical annual owning cost (100 hr/yr): $6,000–8,000 all-in excluding reserves; add $4/hr for engine reserve and $6/hr for rotor reserve.
• Mechanic familiarity: Rotax-familiar A&Ps are common; gyroplane-familiar A&Ps are not. Expect to travel to a service center for rotor work.

Cavalon and Calidus retain value well — AutoGyro's dominant market share, professional factory build (no amateur-built stigma), and limited supply keep used prices within ~20% of new over the first decade. Primary value drivers:

• Engine choice: Rotax 915iS adds $20–30k over a 912ULS equivalent; 914 turbo adds $12–15k.
• Hours on rotor and engine: Rotor TBO is typically 2,000 hours; engine TBO 2,000 hours. Mid-time examples sell for full book; approaching TBO knocks $15–25k off.
• Pro/patrol package: Cavalon Pro with FLIR provisions and dual-screen panel commands a $30–50k premium.
• New pricing (2024): Kit Cavalon from ~$115k, factory-built "PC Cavalon" from ~$125k base, typical well-equipped 914-powered Cavalon delivered in the US runs $180–220k.
• Used pricing: MTOsport $75–120k, Calidus $95–140k, Cavalon $125–220k depending on hours, engine, and equipment.
• Euro exchange rate: All new pricing is euro-denominated; US buyers should track EUR/USD at order time.

As experimental aircraft in the US, Cavalons are not subject to FAA Airworthiness Directives, but AutoGyro GmbH issues Service Bulletins that reach owners through AutoGyro USA and are effectively mandatory for warranty and insurance purposes. Known recurring items:

• Rotor head bearings: Inspection/replacement interval per SB; expensive if neglected ($2–5k parts).
• Pre-rotator clutch wear: Routine maintenance item; the Cavalon's hydraulic pre-rotator is more robust than older bendix-style units.
• Rotax 914 turbo TBO discipline: The 914 has a 2000-hour TBO but requires strict oil-change intervals (25 hr) and carb balance; neglect leads to premature turbo failure ($4–6k).
• Tail boom cracking (early MT-03s): Resolved in MTOsport redesign; pre-buy inspection item on pre-2010 airframes.
• Ground resonance: Historically rare in AutoGyro's teetering rotor design but documented in mishandled landings; proper technique is essential.
• Fatal accident pattern: Gyroplanes have a worse accident rate than fixed-wing GA, driven almost entirely by Pilot-Induced Oscillation (PIO) and rotor unloading in pushover maneuvers. The AutoGyro family has a better-than-average safety record versus home-built gyros but still demands rigorous transition training.

Gyroplane insurance in the US is a small, specialized market with only a handful of underwriters (Avemco, Starr, and brokers like BWI gyroplane desk). Typical profile for a well-insured Cavalon owner:

• Hull: $2,500–3,500/year on a $150k hull at 100+ gyroplane hours with transition training.
• Liability: $400–700/year for $1M smooth.
• Transition training requirement: 10–25 hours dual with a factory-authorized gyroplane instructor is mandatory for coverage; low-time pilots face 2–3x premium loads.
• Underwriting quirks: Hours in fixed-wing don't count — only gyroplane hours move the needle. A 10,000-hour ATP with zero gyro time pays student rates for the first 50 hours.
• Patrol/commercial ops: Cavalon Pros used for pipeline patrol require commercial policies at 2–4x private rates.
