Globe/Temco Swift GC-1B

The Globe Swift is a sleek, all-metal, two-seat, retractable-gear, low-wing taildragger produced from 1946 to 1951. Designed by K.H. "Bud" Knox and first flown in January 1945, the GC-1A received its type certificate on 7 May 1946. With its bubble canopy, flush-riveted skin, and fighter-like lines, the Swift was marketed as a civilian equivalent to the wartime fighters returning pilots had been flying — and its handling lived up to the look.

Production was split between Globe Aircraft Company in Fort Worth and Texas Engineering & Manufacturing Company (TEMCO), which was originally brought in as a subcontractor. When Globe slid into bankruptcy in 1947 after massive over-production outpaced demand, TEMCO acquired the type certificate, tooling, and remaining inventory and continued production through 1951. Total production was roughly 1,521 airframes: approximately 408 GC-1As with the 85 hp Continental C-85, and around 833 GC-1Bs with the 125 hp Continental C-125 (504 by Globe, 329 by TEMCO), plus continued TEMCO production.

The Swift is the definitive "owner's airplane." Fewer than 700 remain on the U.S. registry, and the type is sustained almost entirely by the Swift Museum Foundation, which purchased the type certificate and tooling from Univair in the early 1980s — making it the only type club in the world to own its aircraft's TC. Swifts today are overwhelmingly owned by enthusiasts who value sporty handling, ramp appeal, and community more than speed-per-dollar efficiency. See Ryan Navion for the other North American post-war all-metal retractable, and Beechcraft Bonanza 35 V-tail (Early) for the four-seat contemporary that dominated the market the Swift could not.

Virtually every surviving Swift has been re-engined at some point. The 210 hp Continental IO-360 is the most popular "big engine" conversion, transforming the airplane into a genuine 160+ KTAS cruiser. Merlyn Products, the Swift Museum Foundation, and various shops hold STCs for 90, 145, 150, 180, 200, 210, and 220 hp installations, with gross-weight increase STCs bringing MTOW as high as 1,970 lb.

Stock GC-1B numbers (125 hp, fixed-pitch prop) are pedestrian: roughly 120 KTAS cruise, 420 NM range, 1,710 lb gross. A stock Swift is not fast — a C-172 will keep up. The airplane's reputation for speed comes entirely from the modified examples. A 210 hp IO-360 Swift with a constant-speed prop and gross-weight STC will cruise 155-165 KTAS on 10-11 GPH and climb 1,500+ fpm off a sea-level runway.

Because no two modified Swifts are alike, published performance charts are nearly useless for the fleet. Aviation Consumer and the Swift Museum Foundation both advise buyers that POHs are scarce and that each airplane's true numbers must be established by test flight. The V-speeds above reflect the GC-1B book; modified airframes see Vne and Va ratchet upward per STC paperwork.

The Swift is crisp and honest in roll, tight in the stall (it breaks clean but without vice at around 52 KIAS flaps down), and demands respect on landing: the short-coupled tailwheel geometry and narrow main gear track make it a handful for low-time tailwheel pilots, especially in crosswinds. It is often described as "a taildragger that punishes sloppy feet."

With a stock 571 lb useful load and 28 gal (168 lb) of fuel, a GC-1B carries roughly 400 lb of people and bags with full fuel — enough for two 180-lb occupants and 40 lb of baggage. Full fuel + two average adults leaves no margin for bags. In practice most Swift pilots depart with partial fuel for local flying and fill up only when a long leg demands it.

Range scenarios (stock GC-1B, 7.5 gph, 122 KTAS, 45 min reserve):

• Full fuel, 2 pax, 40 lb bags: ~400 NM no-wind. Comfortable two-leg day.
• Tabs only (20 gal), 2 pax, 60 lb bags: ~260 NM. Typical weekend-trip loading.
• Solo, full fuel, 100 lb bags: ~420 NM.

Modified 210 hp Super Swifts with 36.8+ gal long-range tanks and a 1,970 lb gross STC push these numbers dramatically: full fuel + 2 pax + 100 lb bags becomes viable, and 700-800 NM legs at 160 KTAS are achievable. The delta between a stock Swift and a fully modified Swift on payload-range is larger than on almost any other classic type, which is why two airframes with the same tail number prefix can command 3× the price difference.

• Flight Training (2/10): Two seats, retractable gear, demanding ground handling, specialist maintenance. Useless as a primary trainer; marginal even as a tailwheel transition trainer — see american-champion-citabria or Piper J-3 Cub instead.
• Backcountry/Bush (2/10): Low wing, small prop clearance, narrow gear, delicate belly-mounted gear doors. Emphatically not a backcountry airplane. See maule-m7 or piper-pa-18-super-cub.
• Business Travel (3/10): Two seats only, no IFR platform in stock form, limited baggage (~40 lb), marginal range. A modified 210 hp Swift can make a credible weekend-getaway machine for a couple, but it is not a business airplane.
• Aerobatics (4/10): Not certified for aerobatics, but the airframe is structurally robust and many owners do gentle aileron rolls and loops informally. The stock 125 hp lacks vertical performance; 180+ hp conversions improve this. For real aerobatics see american-champion-decathlon or pitts-s-2.
• Cross-Country (5/10): Stock GC-1B is slow and short-legged; a 210 hp Super Swift with long-range tanks does 700-800 NM at 160 KTAS, making it a legitimate two-place tourer. Mooney M20C Mark 21 / Ranger is the faster and more efficient alternative.
• Cargo Hauling (1/10): 571 lb useful load stock, no baggage volume, no cargo door. Disqualified.
• Local Fun Flying (9/10): This is the Swift's mission. Ramp appeal, sporty handling, bubble canopy, community at every fly-in, classic warbird aesthetic for a fraction of a T-6's cost. Few airplanes are as rewarding for VFR-weekend-morning flying.
• Surveying (3/10): Poor visibility over the nose, no belly port provisions, limited loiter time. Not a survey platform.

Stock Swifts shipped with minimal instruments — airspeed, altimeter, turn-and-bank, compass. Most survivors have been updated multiple times. Typical panel tiers:

• Day-VFR budget ($35-55K airplane): Round gauges, handheld or uninstalled comm, no transponder or ADS-B compliance (grounded from Mode C veil until upgraded). Buyers should budget $4-6K for a basic tailBeacon or uAvionix ADS-B Out install.
• IFR-legal mid-tier ($60-85K): Single nav/comm, used GNS 430W, Mode S transponder with ADS-B Out, basic autopilot rare. See Avionics Pricing Reference for install costs.
• Modern sport panel ($85K+): Dynon or Garmin G3X Touch (installed under non-required-equipment AML STC), GTN 650Xi, dual-axis autopilot. Typically found on Super Swift restorations and owner-flown show airplanes.

The Swift's small panel opening (originally sized for 1946 instruments) makes modern avionics retrofits tight but not impossible.

The Swift is one of the most STC'd airplanes in general aviation. Major modifications:

• Continental IO-360 (210 hp) conversion: The most popular "big engine" upgrade. ~+30 KTAS cruise, ~+500 fpm climb. Install cost (engine + mount + cowl + prop + paperwork) runs $55-80K on top of base airframe.
• Lycoming O-320/O-360 (150-180 hp) conversion: Merlyn Products and Swift Museum Foundation STCs. Lower cost than the IO-360 path, ~+15-20 KTAS.
• Constant-speed propeller STCs: Hartzell and McCauley conversions, typically bundled with engine upgrades.
• Gross weight increase STCs: Raise MTOW to 1,850 or 1,970 lb depending on engine. Essentially required to realize the benefit of the big engine conversions.
• Fuel capacity increase: Long-range tanks bringing total capacity to 36.8+ gallons, pushing range past 700 NM on a 210 hp airframe.
• One-piece windshield and modernized canopy: Cosmetic but common.
• Gear door deletion/simplification STCs: Improves maintenance reliability at a small speed cost.

Because paperwork discipline across 80 years of modifications varies wildly, a pre-buy must include a forensic 337/STC audit. See Aircraft Valuation Methodology for how STC pedigree affects value.

The Swift is sustained by the Swift Museum Foundation (Athens, TN), which holds the type certificate, the original Globe/TEMCO tooling, and the original factory drawings. The Foundation manufactures PMA parts, maintains a parts store, operates an annual fly-in at its home field, and provides technical support via the "Monty the Answer Man" archive and direct member hotline. Foundation membership is effectively required to purchase PMA parts.

• Parts availability: Good for airframe items via the Foundation; poor for original Continental C-125 engine parts; excellent for the Lycoming and IO-360 conversions since those engines are mainstream.
• Mechanic familiarity: Specialist. A general A&P without Swift experience will struggle with the landing gear system and airframe quirks; most Swift owners travel to or ship to a known Swift shop for major work. Notable Swift specialists cluster around Athens TN, Texas, and the upper Midwest.
• Annual inspection cost: Typically $2,500-$5,000 without squawks; $8-15K is not unusual for a first annual after acquisition or for a deferred-maintenance airframe.
• Expensive items: Gear hydraulic pump overhaul ($2-4K), cylinder work on original C-125 (if parts can be found), fabric re-cover on early elevators, wing attach fitting inspections and replacement, cowling and gear door repair.
• Annual cost envelope: Budget ~$9,000-12,000/year all-in for a flying Swift (100 hr/yr), including insurance, hangar, fuel, reserves, and annual. See Maintenance Ecosystem for reference baselines.

Current market (2026) ranges approximately $35K-$110K, with a typical mid-market Super Swift around $65K. Key drivers per Aircraft Valuation Methodology:

• Engine installed: A stock 125 hp C-125 airframe is worth less than a run-out 210 hp IO-360 airframe. The IO-360 conversion alone can represent $40-60K of installed value.
• Time since major overhaul: With C-125 parts scarcity, a near-TBO original engine is a liability, not an asset — the next overhaul may force a re-engine decision.
• Paperwork completeness: Clean 337/STC trail is worth 15-25% of airframe value on this type.
• Cosmetics and paint: Swifts are show airplanes; ramp appeal drives price more than on utility types. A fresh paint job in period-correct scheme adds $10-15K.
• Avionics: Modern IFR or sport panel adds $10-25K, but many buyers value a period-correct panel over glass.
• Gear door and belly condition: A Swift with straight belly skins and properly rigged gear doors commands a premium.

Recent market examples: 1946 GC-1B at $49,900 (project-grade), 1946 GC-1B at $72,000 (3,500 TT, serviceable), 1946 GC-1B at $109,000 (fresh annual, restored), high-end restorations up to $250,000.

• Wing spar inspection: The Swift's two-spar wing structure has been the subject of recurring inspection ADs addressing corrosion and cracking in the main spar carry-through and attach fittings, particularly on airframes operated in coastal environments. The Swift Museum Foundation maintains inspection guidance and supplies replacement parts.
• Landing gear electro-hydraulic system: The Swift's gear retracts inward hydraulically via an electric pump. The system is reliable when maintained but has many unique components; leaks, pump failures, and sequencing gremlins are the single most common shop complaint. Budget for periodic actuator overhauls.
• Gear door rigging: Belly-mounted main gear doors are fussy to rig and prone to minor damage from hangar rash and unpaved operations.
• Tailwheel attach and rudder cables: Small tailwheel unit; cable wear is a recurring squawk.
• Control surface fabric and balance tabs (early airframes): Original fabric-covered elevators on some early GC-1As; most have been recovered or converted to metal.
• Continental C-125 parts scarcity: The original engine is long out of production and cylinders/cases are rare. This is a major reason most surviving Swifts have been re-engined.
• Pre-buy red flags: Missing 337s, undocumented engine or gross-weight STCs, corrosion in the wing root and landing gear attach area, gear system that cycles slowly or unevenly, and recent paint hiding skin issues.

The Swift sits in the vintage retractable tailwheel insurance bucket — one of the more expensive categories for its hull value because of the combination of high claim frequency (ground-loops, gear-up landings) and specialist repair cost. Per AOPA Insurance Services and Swift Museum Foundation guidance:

• Low-time pilot (100 hr TT, 10 hr tailwheel, 10 hr retract): ~$2,200-2,700/year on a $45K hull.
• Experienced pilot (100+ hr tailwheel, 100+ hr retract): ~$1,400-1,900/year on a $45K hull.
• Well-qualified Swift-current owner: Can drop to ~$1,100-1,400/year after three years on type with no claims.

Underwriters will typically require a minimum 5-hour checkout with a Swift-current CFI before issuing a policy, and many will mandate annual recurrent training. Hull values above $100K draw additional scrutiny. See GA Insurance Underwriting for category baselines.
