Van's RV-8 / RV-8A
Lycoming O-360-A1A, 180 hp (carbureted); IO-360 200 hp also common
The RV-8 is what the RV-4 grew up into. It's a tandem two-seater with more cabin room, more fuel, and a heavier-duty airframe meant for serious aerobatic use. Most run a 180 to 200 hp Lycoming, cruise at 170 to 185 KTAS, and burn 8 to 10 gph. The fuselage is wider at the shoulders than the RV-4 and the rear cockpit is genuinely usable by a normal-sized adult, which makes the RV-8 work as a sport airplane that can also take a passenger somewhere.
Like every Van's design, the RV-8 splits along builder versus buyer lines on cost and maintenance. The fleet is still in active kit production as of mid-2026, so used inventory is varied and recent completions are common. This page covers what an RV-8 actually costs to own, how it compares to the RV-7 for a side-by-side buyer, and what to check on a pre-buy.
History
Van's introduced the RV-8 in 1995 as the modern replacement for the RV-4. The brief was straightforward. Keep the tandem layout that experienced RV-4 owners loved. Add cabin width. Add fuel. Add useful load. Make the airplane capable of carrying a fully-equipped passenger on a real cross-country trip without making the pilot feel cramped. The result was a noticeably larger airplane than the RV-4 with a similar visual signature.
The RV-8 found a market among aerobatic pilots who wanted something sportier than an RV-7 but more practical than a single-seat aerobatic competition airplane. Tandem seating offers better visibility for both pilot and passenger and centers the cabin on the roll axis, which makes the airplane feel more responsive in aerobatic maneuvering than a side-by-side design.
Van's continues to ship RV-8 kits as of 2026, though the volume has tapered as builders gravitate to the newer RV-14. As of mid-2026, Van's reports about 1,400 RV-8s flying with another 600 in build. The fleet skews newer than the RV-6 fleet, which means used examples often have modern avionics and current paint.
Variants
RV-8 (taildragger)
1995-presentThe taildragger configuration. About 90% of completed RV-8s are taildraggers. Better aerobatic feel and slightly faster. Insurance is meaningfully higher than the RV-8A unless you have current tailwheel time.
RV-8A (nosewheel)
1995-presentNosewheel version. Easier transition for non-tailwheel pilots but loses some of the aerobatic character. About 10% of the fleet. Used 8A airplanes are less common and tend to trade at a small discount.
Performance
Performance scales with engine. A 180 hp O-360 RV-8 with a Hartzell constant-speed prop cruises at 170 to 175 KTAS on 8 to 9 gph. The 200 hp IO-360 angle-valve version turns 175 to 180 KTAS at similar fuel burn. A 215 hp IO-390 RV-8 climbs better at altitude and runs 180 to 185 KTAS at 9 to 10 gph. The IO-390 isn't common in the RV-8 fleet, but where it appears it's the fastest and best-climbing setup.
Useful load is solid for an aerobatic two-seater. A typical 200 hp RV-8 has about 580 to 620 pounds of useful load. Full fuel is 42 gallons (252 pounds), leaving 320 to 370 pounds for two adults and bags. The tandem cabin makes the rear seat usable for a normal-sized adult, which is the big improvement over the RV-4. Aerobatic limits are +6/-3 g. The airframe was designed for sustained inverted flight, which the RV-4 was not.
Powerplant
The Lycoming O-360 (180 hp) is the most common engine and the canonical choice. The IO-360 angle-valve (200 hp) is the next most common, and the IO-390 (215 hp) shows up on more recent builds. All three are parallel-valve or angle-valve four-cylinder Lycomings with a published TBO of 2,000 hours per Lycoming Service Instruction 1009 BE. In experimental service that number is advisory.
Field overhaul of an O-360 runs $28,000 to $42,000 in 2026 at a name-brand shop. The IO-360 angle-valve adds $5,000 to $10,000 to overhaul cost because of cylinder, valve train, and accessory differences. The IO-390 is in the same neighborhood as the IO-360 angle-valve. Owner-assisted overhauls are legal in experimental service and can cut labor costs by 30 to 40 percent.
The Hartzell constant-speed prop is almost universal on RV-8 airplanes. There's a 2,400-hour or six-year overhaul cycle per Hartzell Service Letter HC-SL-61-61Y Rev 12, at $3,000 to $6,000 in 2026 for the typical RV-8 prop. The higher cost versus the RV-6/RV-7 reflects the heavier-duty propeller specs the RV-8 uses for aerobatic compatibility.
Cost of ownership
Hourly operating cost on an RV-8 runs slightly higher than an RV-7 because most of the fleet has a more capable engine and a heavier-duty propeller.
If you built it: fuel runs $50 to $65 per hour at $5.50 to $7 per gallon and 8 to 10 gph. Engine reserve is $14 to $25 per hour depending on whether you have an O-360, IO-360, or IO-390. Prop reserve is $1 to $3 per hour. Airframe maintenance reserve is $7 to $13 per hour, slightly higher than the RV-7 because aerobatic use accumulates stress. All-in at 100 hours a year is $95 to $140 per hour, plus $3,500 to $6,500 in annual fixed costs.
If you bought it used: realistic all-in at 100 hours a year is $120 to $170 per hour. Insurance is the biggest variable. Aerobatic use on an RV-8 raises premiums versus an identical airplane flown only cross-country. Underwriters want to see current aerobatic experience or a clear non-aerobatic operating profile.
Acquisition cost in mid-2026 runs $95,000 to $135,000 for a well-equipped used RV-8 with a 180 hp O-360 and a recent panel. A 200 hp IO-360 example with current avionics runs $130,000 to $175,000. A new build with a 200 hp engine, glass panel, and current paint typically lands at $200,000 to $260,000 in total cost, with 1,500 to 3,000 hours of builder labor on top.
| Fixed cost | Range | Frequency |
|---|---|---|
| Hangar RV-8s fit a standard T-hangar. Aerobatic owners often opt for end-T or open-bay storage for easier propeller clearance. | $200–$500 | monthly |
| Condition inspection (A&P sign-off, non-builder) Aerobatically-flown airplanes need more thorough inspections than cross-country airplanes. | $500–$1,200 | annual |
| Insurance (builder, current aerobatic time) | $2,000–$3,500 | annual |
| Insurance (used buyer, no aerobatic time) Aerobatic use raises premiums versus non-aerobatic operation. Underwriters discount once you build hours in type. | $2,800–$5,500 | annual |

Common issues & gotchas
Build quality variance
highLike every Van's design, the RV-8 has been built by hundreds of different people. Build quality varies. A pre-buy should be done by an RV-knowledgeable inspector, especially one familiar with the heavier-duty wing attach and tail surfaces on the RV-8. Budget $1,500 to $2,500 for a thorough pre-buy on an aerobatically-used airplane.
Aerobatic stress and engine mount fatigue
highRV-8s used aerobatically accumulate stress on the engine mount, tail surfaces, and gear legs. A pre-buy should include dye-penetrant inspection of the engine mount welds, a careful look at the tail attach hardware, and a review of the operating profile. An RV-8 flown only cross-country wears differently than one used in aerobatic competition.
Repairman certificate doesn't transfer
moderateThe original builder's repairman certificate stays with the builder. Used buyers can still do most of their own maintenance, but the annual condition inspection requires an A&P sign-off. On an aerobatically-flown airplane, that inspection should be done by someone who understands aerobatic stress patterns.
Cylinder wear from aerobatic use
moderateAerobatic operation accelerates cylinder wear. Top overhauls are common between 1,000 and 1,500 hours on aerobatically-used RV-8 engines, versus 1,500 to 1,800 hours on cross-country examples. Verify cylinder compression and borescope condition on any pre-buy.
Canopy and bubble cracks
moderateThe sliding bubble canopy is a wear item. UV exposure and aerobatic G-loading both contribute to cracking. Replacement canopies run about $1,500 plus installation labor.
Older avionics on early builds
lowFirst-generation RV-8 builds from the late 1990s and early 2000s often have aging avionics and wiring. Modern glass panel upgrades run $20,000 to $40,000 depending on equipment choice.
Who it's for
Good fit for
- ✓ Tailwheel-current pilots who want a fast tandem aerobatic airplane
- ✓ Owners who fly aerobatics regularly and want a capable competition or sport airplane
- ✓ Pilots who want a passenger-capable tandem with real cross-country range
- ✓ Builders who like the tandem layout and want a modern airframe to build it on
- ✓ Buyers who can budget for a thorough RV-specific pre-buy
Less good for
- ✗ Pilots who carry passengers regularly and want easy two-up conversation
- ✗ Buyers without current tailwheel and aerobatic experience
- ✗ Owners who want to outsource all maintenance
- ✗ Pilots who don't fly aerobatics and just want fast cross-country (the RV-7 is the better choice)
The verdict
The RV-8 is the right answer when you want a tandem aerobatic airplane that can also carry a passenger on a cross-country trip. The cabin is genuinely usable in both seats, the airframe handles sustained inverted flight, and the performance is in the same league as the RV-7 with a more capable aerobatic envelope. For an aerobatically-current pilot who values the tandem layout, nothing else in the Van's family does it better.
For a cross-country-only mission profile, the RV-7 is a better fit. Side-by-side seating is easier on the passenger, the cabin is more practical for bags, and insurance is meaningfully cheaper. Buy the RV-8 because you actually use the aerobatic capability, not because it looks the part.

Frequently asked
How much does a used Van's RV-8 cost in 2026? +
A well-equipped airplane with a 180 hp O-360 and modern panel runs $95,000 to $135,000. A 200 hp IO-360 example with current avionics runs $130,000 to $175,000. New builds with 200 hp engines, glass panels, and current paint typically land at $200,000 to $260,000 in total cost. The RV-8 fleet skews newer than the RV-6 fleet, so used inventory often has updated avionics.
Is the RV-8 a serious aerobatic airplane? +
Yes. The RV-8 is rated for +6/-3 g and was designed for sustained inverted flight, which the RV-4 was not. The fuel system supports inverted operation with an optional flop tube, the canopy and structure are sized for aerobatic G-loading, and the tandem layout puts the pilot near the roll axis. It's competitive in IAC Sportsman category and capable in Intermediate.
Should I buy an RV-8 or an RV-7? +
Buy the RV-8 if you fly aerobatics regularly and value tandem visibility. Buy the RV-7 if you mostly fly cross-country with a passenger. Performance numbers are within a few knots of each other for the same engine. The RV-7 has a more practical cabin for passenger comfort and bags. Insurance is meaningfully cheaper on the RV-7.
What's the typical fuel burn for an RV-8? +
A 180 hp O-360 RV-8 burns 8 to 9 gph at cruise. The 200 hp IO-360 version burns 8.5 to 10 gph. The 215 hp IO-390 burns 9 to 10.5 gph. Lean-of-peak operation can pull cruise burn down by 1 to 1.5 gph at moderate power settings.
Can I do my own maintenance on a used RV-8? +
Mostly yes. Experimental rules let you do most maintenance and repairs yourself. The annual condition inspection requires an A&P sign-off at $500 to $1,200 a year. On an aerobatically-flown airplane, the inspection should be more thorough than on a cross-country-only airframe, so the high end of that range is realistic.
Is the RV-8 hard to land? +
It's a taildragger with light controls, so it rewards current tailwheel pilots and punishes sloppy ones. The RV-8 is forgiving by taildragger standards thanks to a wider gear track and predictable handling, but it's not as forgiving as an RV-7A. Insurance underwriters typically want 25-plus hours of tailwheel time and a transition checkout with a current RV pilot.
