Pulsar XP / Pulsar III

The Pulsar is a two-seat, side-by-side, low-wing composite homebuilt designed by Mark Brown and first produced by Aero Designs of San Antonio, Texas, with the prototype flying in 1985. The original Pulsar was powered by the 64 hp Rotax 532 two-stroke, but the design hit its stride in 1992 with the introduction of the Pulsar XP powered by the 80 hp four-stroke Rotax 912UL. Later the line passed through Pulsar Aircraft Corporation (Aero Resources) and eventually SkyStar, which produced the enlarged Super Pulsar 100 and Pulsar III with wider cockpits (44" vs 39"), strengthened landing gear, and larger engine options including the Rotax 912ULS (100 hp), turbocharged Rotax 914 (115 hp), Jabiru 2200 (85 hp), and Jabiru 3300 (120 hp). Approximately 500 kits were claimed delivered by 2005, when factory production ended. Today it is flown by pilots who want a slippery, fuel-efficient, sporty cross-country two-seater with trainer-like handling and microlight-like operating costs. See Aircraft Valuation Methodology for general composite experimental valuation context.

Real-world Pulsar XP cruise is a widely reported 140-145 mph (122-126 KTAS) at 4500 rpm on the Rotax 912, burning 3.5-4.2 gph of mogas — a remarkable speed-per-gallon number among two-seat experimentals. The airframe is very slippery, so descent planning must begin early and power reductions must be gradual to avoid shock-cooling the Rotax. Climb rate of 1200 fpm solo is strong, but the small wing and light wing loading make the airplane bouncy in turbulence. Density altitude affects the Rotax less than a carbureted Lycoming, but the small airframe is sensitive to weight — at gross weight with two adults the climb drops noticeably. VNE is reported at 160 mph (139 KIAS), and the airplane is not spin-approved or aerobatic.

With a typical empty weight of 560 lb and max gross of 1150 lb, useful load is ~590 lb. Full 20-gallon fuel load is 120 lb, leaving 470 lb for occupants and baggage:

• Full fuel + solo pilot (200 lb): 270 lb of baggage/headroom — essentially unlimited personal gear. Range ~520 NM with reserves at 4 gph.
• Full fuel + two adults (400 lb): Only 70 lb of baggage, bumping against gross. Doable but tight.
• Two large adults (450 lb) + baggage (30 lb): Fuel limited to ~110 lb / 18 gallons, yielding ~460 NM range.
• Max range solo: ~600 NM with 45-minute reserve at economy cruise

The Pulsar is fundamentally a pilot-plus-passenger cross-country cruiser for two average-sized adults, not a two-heavyweight airplane. Baggage volume is more limiting than weight — the hat shelf behind the seats is small.

• Flight Training (2): Too light, too slippery, and too weight-sensitive for primary training. A few owners transition into them but it is not a trainer platform.
• Backcountry (2): Low wing, small tires, fragile nose gear, and limited prop clearance rule out rough-field work.
• Business Travel (3): Fast and fuel-efficient for the class, but experimental status, single-pilot-plus-bag payload, and lack of meaningful IFR capability limit serious business use.
• Aerobatics (2): Not approved for aerobatics; spin recovery not demonstrated at gross. Responsive controls, but this is not an aerobatic airframe.
• Cross-Country (6): This is where the Pulsar shines for the $50K budget tier — 125 KTAS on 4 gph gives 500+ NM range with meaningful reserves. Payload limits it to one pilot plus a passenger with light bags.
• Cargo Hauling (1): Tiny cockpit, tiny baggage area, ~200 lb useful load after full fuel and one pilot.
• Local Fun Flying (9): Core mission. Sporty handling, panoramic visibility, mogas fuel burn under $20/hour, and a distinctive composite ramp presence make this one of the best "Sunday morning fun flyer" experimentals ever built.
• Surveying (3): Visibility is decent but endurance, payload, and stability are not optimized for survey work.

Pulsars are almost exclusively VFR day/night panels. Typical configurations:

• Budget ($2-5K panel): Steam gauges, handheld GPS, basic comm, no transponder or ADS-B.
• Mid ($8-15K panel): One Dynon D10A or GRT Mini EFIS, Garmin GTR-200 comm, Garmin GTX-335 ADS-B out, Garmin aera 660 portable.
• High ($20-35K panel): Dual Dynon SkyView HDX or Garmin G3X Touch, autopilot servos, integrated ADS-B in/out, engine monitor tied to the Rotax.

No certified IFR installations are known. The Rotax 912 does not have a vacuum pump, so all attitude information is electric.

As an experimental amateur-built, the Pulsar has no STCs — modifications are handled under the builder's repairman certificate or A&P sign-off per the operating limitations. Common field modifications:

• Engine upgrade Rotax 912UL -> 912ULS (80 -> 100 hp) — adds ~10 KTAS cruise, ~$8K for used engine swap
• Jabiru 3300 conversion — aftermarket mount, adds cruise speed and reduces fuel burn compared to 914
• Dynon/Garmin EFIS retrofits
• Airmaster constant-speed propeller — improves climb and short-field; ~$7-9K installed
• Wheel pants and gear leg fairings on older Pulsars missing them (~5-7 KTAS delta)
• Hydraulic Matco brake retrofit on early band-brake airframes

Per Maintenance Ecosystem, Pulsar maintenance is manageable but specialized:

• Parts availability (fair): No factory. The Pulsar Builders' Group (active email list and annual Kansas fly-in) manufactures replacement parts and supports owners. Common hardware is available from Aircraft Spruce. Proprietary composite parts can require fabrication.
• Mechanic familiarity (specialist): Rotax 912 requires a mechanic with Rotax Service course (Level A/B at minimum). Composite airframe repair requires a builder or composite-experienced A&P. Not every field has one.
• Annual condition inspection: $500-1,500 DIY for the repairman-certificate holder; $1,500-3,000 at a Rotax-qualified shop
• Expected annual operating cost: $3,000-5,000 including reserves for Rotax hose replacement and gearbox inspection
• Expensive items: Rotax rubber replacement ($1.5-2K every 5 years), gearbox overhaul at 1000-1500 hours ($3-4K), composite repair from hangar rash ($2-10K depending on location), carb rebuild kit
• Fuel: Mogas 91 AKI is the preferred fuel, making operating costs dramatically lower than 100LL burners

Per Aircraft Valuation Methodology, Pulsar pricing is driven more by engine time, panel, and rib vintage than by airframe hours. Typical tiers (2026 market):

• $35-45K: Original Pulsar 582 or early 912 XP with steam gauges, high-time engine, band brakes or questionable ribs
• $45-65K: Mid-1990s XP with Matco brakes, solvent-resistant ribs, mid-time 912, single EFIS
• $65-80K: Low-time Super Pulsar 100 / Pulsar III with 912ULS, dual EFIS, ADS-B, Airmaster prop
• $80-90K+: Pulsar III 914 or Jabiru 3300, glass panel, autopilot, recent engine

Rotax 912 engine time is the single largest value swing: a fresh-overhaul 912 adds ~$12-15K over a run-out engine. Dynon/Garmin glass adds ~$8-12K over steam. Constant-speed prop adds ~$5-7K. Experimental airplanes do not hold value as well as certified equivalents, and Pulsars specifically take a discount because the factory is gone.

Experimental amateur-built aircraft are not subject to FAA ADs, but Rotax service bulletins apply to the engine. Known pattern problems:

• Early band brakes — ineffective and prone to fade; replace with Matco hydraulic kit
• Solvent-dissolvable polystirene wing ribs on pre-1994 airframes — any fuel leak or solvent spill can delaminate ribs; later brown solvent-resistant foam ribs fixed this
• Delicate nose gear — ground loops and firm landings bend the steel nose leg; SkyStar-era strengthened gear is the fix
• Fuel shutoff valve leaks over time; original fuel plumbing ran through the cockpit
• Rotax 912 gearbox — per Rotax SB, requires periodic slipper-clutch friction checks and eventual rubber dampener replacement
• Carburetor sync drift on the Rotax 912 dual-carb setup
• Hose replacement — Rotax mandatory 5-year rubber hose replacement is a $1-2K shop visit
• Composite repair skill scarcity — hangar rash or a prop strike requires a composite-qualified shop

Pre-buy should include verification of builder serial number with the Pulsar Builders' Group, Rotax logbook completeness, rib foam type, and a careful composite inspection for delamination and UV damage.

Per GA Insurance Underwriting, the Pulsar sits in the experimental composite two-seat category:

• Hull premiums: 2.5-4% of hull value annually, typically $1,200-1,600 for a $55K hull
• Liability: $200-400/year for $1M smooth is common; some underwriters only write $100K/$100K on experimentals
• Underwriter preferences: Avemco, Falcon, and Starr will write Pulsars; some majors decline experimental composites entirely
• Pilot requirements: Typically 200+ hours total, 25+ hours in make/model or transition training with a Pulsar-experienced CFI. Low-time pilots face surcharges or declines.
• Quirks: Loss history on Pulsars includes runway excursions (nose gear) and off-airport landings after fuel exhaustion from the small tanks — both are underwriter red flags.
