Rutan Model 33 VariEze

The Rutan Model 33 VariEze is Burt Rutan's seminal canard pusher that reshaped amateur-built aviation in the late 1970s. Unveiled at EAA Oshkosh 1975 as a prototype and offered to homebuilders as plans beginning summer 1976, the VariEze introduced moldless composite construction (hot-wire-cut foam cores skinned in fiberglass and epoxy) to a community that had been building tube-and-fabric and sheet-metal airplanes for decades. The canard configuration made the airplane resistant to full aerodynamic stalls and departures — the forward wing stalls first, pitching the nose down before the main wing loses lift — which Rutan marketed heavily as a safety advantage.

By the end of 1979 Rutan Aircraft Factory had sold more than 3,000 plan sets; by 1980 around 200 were flying with roughly 2,000 under construction. Completions tapered off after RAF stopped selling plans in 1985 in the wake of a Long-EZ product-liability suit, and as of the early 2020s approximately 800 VariEzes are estimated to have ever flown worldwide. The type is an orphan design in the literal sense — no factory, no parts catalog, no kit vendor — supported entirely by a tight-knit builder community through the Central States Association newsletter, the Canard Aviators list, canardzone.com forums, and Cozy Girrrls (Chrissi and Randi) who machine replacement metal parts.

The airplane that comes out of a good build is remarkable: a two-seat tandem retractable that cruises at 160+ knots on 5 gph behind a 100 hp Continental O-200. The price for that efficiency is a 1,050 lb gross weight, a 465 lb useful load that is almost fully consumed by two adults and fuel, non-trivial runway requirements, and a handling personality that rewards proficiency. It is a single-mission airplane — fast, efficient cross-country fun — and it does that job better than almost anything else at its price point.

Later VariEzes commonly received winglet modifications, strake-integrated fuel tanks (originally fuselage-mounted), Cozy Girrrls machined landing brake and gear hardware, and electrical-system upgrades. Most flying examples today are heavily modified from the 1976 plans baseline. The Long-EZ (Model 61) is a larger, refined successor and is covered separately: see rutan-long-ez.

The published 165 KTAS book number assumes a clean, on-weight, correctly-built airframe with a tight cowling and a small-diameter prop turning efficiently behind the pusher installation. Real-world fleet cruise varies widely — 150-165 KTAS is typical, with heavier or draggier builds closer to 140 KTAS. Fuel burn at economy cruise can fall below 5 gph, giving the type its legendary 30+ mpg figures.

Canard aerodynamics impose a penalty at low speed. The forward canard must stall before the main wing, which means the main wing never reaches its full coefficient of lift. Approach speeds are high (roughly 75-80 KIAS over the fence) and landing rolls are long for a 1,050 lb airplane. There are no flaps in the conventional sense; pitch authority and a belly-mounted landing brake manage the descent. Density altitude hurts takeoff performance disproportionately because the canard is already operating near its stall limit during rotation.

Climb is strong when light — 1,600-2,000 fpm solo with an hour of fuel — but falls off quickly at gross. Service ceiling in practice is 18,000-20,000 ft depending on build and engine condition; some owners have operated above 20,000 ft on oxygen.

The Vne is 191 KIAS (220 mph) and the airframe was load-limited to +2.5g / -1.5g after wing problems surfaced in early fleet experience. This is not an aerobatic airplane despite its sporty feel.

The VariEze's 465 lb useful load is the single most limiting spec on the airframe. Two scenarios:

• Full fuel + pilot only: 24 gal × 6 lb = 144 lb fuel, leaves 321 lb for pilot and baggage. A 200 lb pilot with a 20 lb flight bag leaves 100 lb of baggage margin — easily within limits. Range at 5.1 gph with 45-min reserve: approximately 600 nm no-wind at 160 KTAS. This is the airplane's signature mission.
• Two 180 lb adults + baggage: 360 lb occupants, 20 lb baggage = 380 lb, leaving only 85 lb (14 gal) of fuel. Usable range drops to roughly 300-350 nm with reserves. Two large adults cannot make the book range on full tanks without exceeding gross weight — a classic light-two-seater trap.
• Two 220 lb adults: Simply will not work at gross. Many VariEzes are CG-limited before they are weight-limited with two heavy front-and-rear occupants, particularly without strake tanks.

The airplane rewards lightweight pilots, light passengers, and pilots flying alone with full fuel. For cross-country with a companion, baggage is hand-carried essentials only and fuel stops are closer than the range number suggests.

• Flight training (1/10): Single-place instruction is impossible, checkout is difficult, insurance is ruinous, and the handling is unforgiving. Avoid.
• Backcountry (1/10): Fragile composite belly, retractable nose gear, long landing roll, and a prop at the back of the airplane vulnerable to FOD. Categorically unsuitable.
• Business travel (3/10): The speed is attractive but two-seat tandem with negligible baggage, no IFR capability in most examples, and weather sensitivity rule it out for anything but the most casual business mission.
• Aerobatics (1/10): 2.5g limit; stall-resistant design means no spins or traditional aerobatic figures. Prohibited.
• Cross-country (7/10): This is the VariEze's raison d'être. 160 KTAS on 5 gph with 600 nm range is exceptional. Score capped by 2-seat tandem layout, tiny baggage volume, and limited IFR fit. See cross-country.
• Cargo hauling (1/10): 465 lb useful load, no baggage compartment to speak of. Irrelevant.
• Local fun flying (8/10): Sports-car handling, ramp-appeal that stops traffic, and cheap-per-hour operation make it a superb $5-burger machine for owners who enjoy the airplane itself.
• Surveying (2/10): Too fast for useful low-altitude work, no camera ports, no observer seat layout.

Panels in VariEzes are builder-chosen and vary wildly. Three realistic tiers in today's fleet:

• Day-VFR vintage ($1-3k): Original-era King KX-155 or Narco Mk-12D nav/com, encoding altimeter, no transponder upgrade. Many 1980s panels still flying as-built.
• ADS-B minimum ($5-10k): uAvionix skyBeacon/tailBeacon (challenging on composite), Garmin GTX 335, a single 2.25" G5 in the panel cutout, handheld GPS for navigation. The most common modern configuration.
• Glass refresh ($15-25k): Dynon HDX 7", Garmin GNC 255 com, GTX 345 transponder, autopilot servos (difficult to install in a pusher canard). Rare because panel real estate is tiny and composite installations of ADS-B antennas are a project.

IFR certification is legal in Experimental Amateur-Built and a handful of VariEzes fly IFR, but panel space, pitot-static plumbing, and the lack of a backup electrical system typically keep the fleet VFR. See avionics-pricing for cost guidance.

STCs do not apply to Experimental Amateur-Built aircraft; modifications are by builder choice and logged in the aircraft's individual records. Common modifications in the VariEze community include:

• Winglets: Almost universal retrofit on pre-1978 airframes
• Strake fuel tanks: Replace original fuselage tanks with wing-strake tanks for better CG and capacity
• Cozy Girrrls machined hardware: Landing brake actuators, gear attach fittings, canard lift tabs — the primary replacement-parts source for the fleet
• Lycoming O-235 conversion: Common engine upgrade from O-200 for modest additional HP and better parts availability
• Electric nose-gear retract: Replaces the manual crank (labor but popular)
• Larger main gear tires: For softer fields, at a cruise-speed penalty

The VariEze sits in the specialist corner of the maintenance-ecosystem. There is no factory, no parts catalog, no approved repair station network. Owner-maintenance is the norm under Experimental Amateur-Built rules, with condition inspections performed annually by an A&P (no IA required).

• Parts availability (fair): Continental O-200 engine parts are excellent via the certified supply chain. Airframe-specific parts (landing brake, gear fittings, canopy latches) come from Cozy Girrrls, Featherlite (long gone), eBay, and a handful of cottage machinists. Some parts are unobtainium and must be fabricated.
• Mechanic familiarity (specialist): A typical field A&P will refuse to sign a VariEze condition inspection. Canard-experienced inspectors exist in clusters (Mojave, Oshkosh, Lakeland, Central States) but require fly-ins. Budget $1,500-$3,000 for a proper condition inspection by a specialist.
• Annual cost estimate ($4,500): Assumes owner-performed labor, occasional composite repair consumables, O-200 oil changes, and specialist condition inspection. Add $2-3k in years requiring significant composite work.
• Expensive items: Engine overhaul ($18-22k for O-200), canard retrofit to Roncz ($8-15k in materials and labor equivalent), fuel-tank rebuild ($3-6k), canopy replacement ($4-8k).
• Community resources: Canardzone.com forums, Central States Association quarterly, Cozy Girrrls parts and advice, EAA Technical Counselor network for local hands.

Baseline asking prices for flying VariEzes in 2024-2026 run $18k-$45k, with $25-30k typical for a sound, day-VFR, Continental O-200 airplane with mid-time engine and the Roncz canard retrofit. Drivers (see valuation-methodology):

• Engine time: O-200 mid-time ($10k premium for fresh) vs. run-out (deduct $12-15k). Lycoming O-235 installations add $3-5k if recent.
• Canard retrofit: Roncz R1145MS in place of original GU canard adds $4-8k and is a red flag if absent.
• Avionics: ADS-B Out compliance adds $3-5k; full modern glass panels add $10-15k but are rare.
• Builder reputation: A well-known builder with meticulous logs can add 20-30% over an unknown-provenance example.
• Logs and records: Complete build logs, condition-inspection history, and SB compliance are critical. Missing records cut value by 40%+.
• Paint and cosmetics: Composite airframes show age badly; fresh paint adds $5k.

There is no bluebook for the type; Trade-A-Plane and Controller listings are sparse, and most transactions happen on canardzone.com classifieds or through the Central States Association network. Expect 6-18 month sale times in either direction.

Experimental Amateur-Built aircraft are not subject to FAA ADs. However, RAF and the canard community issued numerous mandatory and advisory service bulletins over the life of the design. Known problem areas:

• Canard delamination and original GU canard airfoil: The original GU25-5(11)8 canard airfoil is rain-sensitive (pitch trim changes in visible moisture). Many aircraft have been retrofitted with the Roncz R1145MS canard, originally designed for the Long-EZ — this is a major rebuild but considered a meaningful safety improvement.
• Wing load limits: 2.5g/1.5g placard applied after early wing failures. Verify placarding and any wing inspection history in logs.
• Foam core degradation: UV exposure, fuel spills in strake tanks, and water intrusion can soften polyurethane/polystyrene foam. Non-destructive inspection of composite sandwich is difficult.
• Epoxy quality: 1970s-era Safe-T-Poxy and later RAES epoxies have known lifetime concerns; hot-hangar exposure can cause post-cure failures.
• Nose gear collapse: Manually-cranked retract mechanisms are fragile; belly scrapes from forgotten-gear landings are common and damage the composite fuselage.
• Engine cooling: Pusher cowlings on VariEzes are notoriously marginal; CHT runaway at low airspeeds is a recurring issue.
• Builder quality variance: Two VariEzes with the same paint can be 50 lb apart in empty weight and meaningfully different structurally. Pre-buy inspection by a canard specialist (see Canardzone "condition inspection" guidance) is essential.

Insurance is the single biggest ongoing expense for a VariEze relative to hull value. The combination of experimental category, retractable gear, canard configuration, pusher engine, and single-place checkout difficulty places it in a small underwriting pool. See insurance-underwriting for GA experimental insurance framework.

• Hull coverage: $1,500-$2,500/year for $25-35k hull, liability-only is $400-600/year and is what most owners actually carry.
• Pilot requirements: Underwriters typically want 250+ total time, 25+ retract, 10+ in make and model dual received, and a canard-experienced checkout pilot's logbook endorsement. First-year premiums for low-time-in-type pilots can be 50-100% higher.
• Hull coverage availability: Only a handful of markets (Avemco, Starr, BWI Aviation) will quote hull on a VariEze at all. Hull coverage is often declined outright for pilots under 500 TT.
• Ground handling: Long, low nose and retractable nose gear generate a disproportionate share of claims; insurers know this.
