Kitfox Purchase Price: Kits vs. Ready-to-Fly vs. Used Aircraft
The Kitfox offers multiple acquisition paths, making it one of the most affordable aircraft to own. You can purchase a kit and build it yourself, buy a complete kit, or acquire a pre-built used aircraft. This flexibility is unique among aircraft and significantly impacts total cost.
Kitfox Purchase Options & Pricing
| Purchase Option | Typical Price | Notes |
|---|---|---|
| Airframe Kit (plans/pieces) | $30K–$45K | Requires builder labor + engine |
| Complete Kit (airframe + engine) | $60K–$75K | Ready to build; missing avionics |
| Turn-Key Ready-to-Fly | $85K–$110K | Built kit; includes avionics |
| Used (2010–2015) | $95K–$130K | Older models; varying condition |
| Used (2016–2021) | $130K–$170K | Newer models; modern avionics |
| Used (2022+) | $160K–$210K | Recent builds; premium condition |
One major advantage of Kitfox: experimental amateur-built aircraft typically appreciate better than certified aircraft due to their specialized mission (backcountry/bush flying) and owner-friendly operating costs. A well-maintained Kitfox from 2015 retains 70–85% of purchase value.
Fuel Consumption & Operating Costs
The Kitfox's greatest strength is its astonishingly low fuel consumption. With a Rotax 912ULS engine, the Kitfox burns 3.4–4 gallons per hour at cruise, rivaling the Tecnam P2008 for fuel economy. This translates to incredibly low hourly and annual fuel costs.
Fuel Burn at Different Power Settings
| Flight Phase | Fuel Burn (GPH) | Notes |
|---|---|---|
| Takeoff & Climb | ~7 GPH | Full throttle (brief duration) |
| Cruise (Economic) | 3.4–3.8 GPH | Best range power |
| High-Speed Cruise | 4–4.5 GPH | Higher airspeed |
| Descent & Approach | 2–3 GPH | Idle to light power |
Annual Fuel Costs by Utilization (Avgas @ $5.50/gal)
| Annual Flight Hours | Gallons/Year @ 3.7 GPH | Annual Fuel Cost | Per Hour Cost |
|---|---|---|---|
| 50 hours | 185 gal | $1,018 | $20.35 |
| 100 hours | 370 gal | $2,035 | $20.35 |
| 150 hours | 555 gal | $3,053 | $20.35 |
| 200 hours | 740 gal | $4,070 | $20.35 |
Engine Specifications & Owner-Performed Maintenance
The Kitfox typically uses the Rotax 912ULS engine, though some builders choose Continental or Lycoming engines. The beauty of experimental aircraft ownership is that you can perform all maintenance yourself—eliminating expensive mechanic labor that can run $75–$150 per hour on certified aircraft.

Insurance Costs for the Kitfox
Kitfox insurance is surprisingly reasonable, especially for liability-only coverage. However, premiums vary based on pilot qualifications (requiring 750+ total hours and 250+ tailwheel hours for best rates) and hull value.
Typical Annual Insurance Costs
| Coverage Type | Qualified Pilots | Less Experienced | Notes |
|---|---|---|---|
| Liability Only ($1M) | $384–$505 | $470–$630 | Ground damage coverage included |
| Liability + $50K Hull | $950–$1,200 | $1,500–$2,000 | Moderate coverage |
| Liability + $80K Hull | $1,504–$1,920 | $2,200–$2,750 | Comprehensive coverage |
Pilot Requirements: Most insurers require a Private Pilot certificate, 750+ total flight hours, 250+ tailwheel hours, and 25 hours in the Kitfox type for preferred rates. New aircraft owners or those with fewer hours will pay higher premiums.

Frequently Asked Questions
What is a Kitfox and why is it different from certified aircraft?
The Kitfox is an experimental amateur-built (E/AB) aircraft, meaning it was either constructed from a factory-supplied kit by a homebuilder or built from plans. Unlike certified aircraft, E/AB aircraft have fewer regulatory restrictions and owners can perform their own maintenance. This dramatically reduces operating costs. Additionally, Kitfox aircraft are known for exceptional short-field performance and backcountry capability, making them ideal for bush flying and remote operations.
How much does a Kitfox cost to buy?
A new Kitfox kit costs approximately $45,000 for the airframe alone. A complete ready-to-fly kit (including engine and avionics) runs approximately $70,000. For pre-built used aircraft, prices range from $95,000 for older models to $200,000+ for newer well-equipped models. Most used Kitfox aircraft sell between $120,000–$160,000. Compared to certified singles, Kitfox offers exceptional value.
How much fuel does a Kitfox burn per hour?
The Kitfox with a Rotax 912 engine burns 3.4–4 gallons per hour at cruise power. Some owners report average fuel consumption under 3.5 GPH depending on power settings. At $5.50/gallon Avgas, hourly fuel costs are only $19–$22. Annual fuel costs at 100 hours would be just $2,090–$2,420, making it one of the most economical aircraft to operate.
Can owners perform their own maintenance on a Kitfox?
Yes—this is one of the key advantages of E/AB aircraft. FAA regulations allow experimental amateur-built aircraft owners to perform any maintenance themselves, including major overhauls. This eliminates expensive mechanic labor costs. Owners can perform oil changes, inspections, engine work, and avionics maintenance without hiring a certified mechanic. This can save $5,000–$10,000 annually in maintenance labor.
What is the engine overhaul cost for a Kitfox?
Kitfox aircraft typically use the Rotax 912ULS engine with a 2,000-hour TBO. A new Rotax engine costs approximately $20,000, translating to about $10/hour spread over the engine's life. Most owners won't face an overhaul for 13–20 years of typical operation. If you perform the overhaul yourself (or have a friend assist), labor costs are eliminated entirely.
How much does Kitfox insurance cost annually?
Kitfox insurance varies based on pilot qualifications and coverage. Liability-only insurance ($1M) costs $384–$630/year for qualified pilots. Full coverage (liability + $80K hull) runs $1,500–$2,750/year depending on pilot experience and hull value. Insurance premiums require a Private Pilot license, typically 750+ total hours, 250 tailwheel hours, and 25 hours in type. Less experienced pilots pay higher premiums.
What is the service ceiling and range of a Kitfox?
Most Kitfox models have a service ceiling around 17,000–18,000 feet and maximum range around 600–800 nautical miles depending on fuel capacity and power settings. The aircraft is particularly exceptional in short-field and backcountry performance, with some models capable of takeoff and landing in 500 feet or less. This makes the Kitfox ideal for remote bush flying, not long-distance cross-country work.
Is the Kitfox a tailwheel aircraft?
Most Kitfox models feature conventional tricycle landing gear, though some builders choose retractable or tailwheel configurations. Tricycle-gear Kitfoxes are easier to land and operate than taildraggers but offer less ground clearance for rough surfaces. Tailwheel conversions are popular among backcountry operators for their superior rough-field capability. Verify the specific landing gear configuration when purchasing a used aircraft.
