KITPLANES Guide: Buying a Van’s RV-7

1

By Dave Prizio.

The RV-7 made its debut in the spring of 2001 at Sun ’n Fun as a replacement for the recently discontinued RV-6 series. Some 19 years later it is still selling well but has yet to threaten the record of almost 2700 RV-6/6A completions. With so many choices now available from Van’s and others, it may never reach that number. Nevertheless, a large number of fine RV-7s in both gear configurations are available, so potential buyers shouldn’t have too much trouble finding something to entice them.

Design

The RV-7 originally came with the larger tail found on late RV-6s, but more extensive testing suggested that a still-larger tail would provide better spin recovery. This resulted in kits shipped after May 20, 2002 coming standard with the RV-9 tail. Van’s then made provisions for owners of earlier kits to replace their tails with the larger version (see Van’s service bulletin SB 02-6-1). The RV-7 shares many other parts with the RV-8 and RV-9 series kits in an effort to save money across the line of products.

In order to increase gross weight and useful load, the RV-7 includes a greater wingspan of 25 feet compared to the RV-6’s 23 feet, but the chord and airfoil remain the same. This allows a 200-pound increase in gross weight to 1800 pounds without fudging the factory recommendation. The longer wings also hold four gallons of extra fuel, something much needed with the larger engine options available in the -7. The extra gross weight also comes in handy when builders add autopilots and other more sophisticated avionics, which all tend to increase the empty weight. On the slightly negative side, the extra weight is only partly offset by more wing area, meaning that the RV-7 has a small, 2-knot increase in stall speed over the -6, if the -6’s recommended 1600-pound gross weight is respected.

Following the example of the later RV-6 kits, the RV-7 kits come match hole drilled for easier assembly. The design has remained largely unchanged since then.

Yes, the RV-7 is capable of aerobatics.

In SB 02-6-1, Van’s goes into detail about the aerobatic capabilities of the RV-7. It is worth reading in its entirety if you are seriously considering buying an RV-7 or -7A. In Van’s words, “They were designed primarily as sport/cross-country airplanes with sufficient performance and control authority to safely perform basic recreational aerobatic maneuvers such as loops and rolls. We do not consider aerobatic maneuvers such as high-speed multiple snap rolls and tail slides, which can impose high airframe loads, to meet our definition of sport aerobatics.”

Inverted flight is possible if the builder makes the necessary provisions, but the RV series of airplanes do not have symmetrical airfoils that allow for better performance in upside down or negative-G situations.

Different Configurations

Like the RV-6 before it, RV-7 kits come either with tricycle gear or conventional gear. However, unlike some planes such as the GlaStar, switching from one gear configuration to the other after building is not really an option. You make your choice and live with it. RV-7s are also available with either a sliding or tip-up canopy. Both the gear and canopy options are roughly equally split among the planes available. Conventional gear is said to provide a two-knot speed advantage, but choices individual builders make with engine and propeller options, not to mention their skill at rigging, make such a difference largely irrelevant in a practical sense.

This RV-7A was built with a sliding canopy, but the tip-up canopy is also popular.

There are many more examples of RV-7s available with larger engines and constant-speed propellers than you will find with RV-6s. This is in keeping with the greater expectations and willingness to spend money to meet those expectations found in the typical RV-7 builder. In a very real sense, the advent of the RV-7 series marked the end of the price-conscious era of the RV-6 and ushered in an era where builders wanted more capability out of their planes and were willing to pay for it.

It still matters that you pay attention to empty weight, both from a flight performance standpoint and a utility standpoint. Big angle-valve engines add lots of weight and yield relatively small performance gains. Some of this can be offset with a composite propeller, but not all of it. It is easy to get seduced by a big horsepower number, but each configuration has its pros and cons. Be sure to understand not only the benefits but also the downside of the choices made in the plane you are considering.

What to Look For

The RV-7 is a sturdy plane that holds up well under normal use, but condition does vary from one plane to another, and condition is very important. It is always better to get the best plane you can afford rather than get a cheap plane that needs work to bring it back to excellent condition at your expense. This makes a prebuy inspection vital.

There are a number of service bulletins that should concern you. Hopefully the builder or a subsequent owner has logged compliance with them in the airplane records. Missing service bulletin compliance is a definite negative for you as a buyer. The big ones deal with cracks in various places in the airframe. SB 16-03-28 deals with cracking in the aft wing spars at the inboard aileron hinge bracket attach point. SB 14-02-05 deals with cracks in the elevator spar and SB 14-01-31 deals with cracks in the horizontal stabilizer spar. These typically arise from enthusiastic aerobatic maneuvers that may not have been well executed or are outside of what Van’s considers sport aerobatics. In any case it is important to have a competent person inspect these items for compliance and possible damage. If damage is found, Van’s sells retrofit kits to repair and reinforce the damaged areas. AntiSplatAero LLC also sells kits to reinforce the tail attachment points in hopes of preventing future damage.

A service bulletin that applies to all RV trikes is SB 14-12-22 that calls for inspection and correction, if needed, of the installation of the nosewheel stop. This is a simple but important matter. Beyond that, there are a number of other service bulletins that should be addressed by any owner of a plane you are considering. See Van’s website for all of the service bulletins.

The need for a prebuy inspection of any potential purchase by someone familiar with the type cannot be overemphasized. This inspection should include a thorough review of the aircraft service records and a physical inspection of the airplane. Anything likely to be found in a prebuy inspection is likely to cost money to correct. The idea is to be sure you aren’t the one who is going to pay for fixing it unless you have agreed to do so.

Engine Options

One advantage of the RV-7 over the RV-6 is the ability to accommodate more engine choices, including the angle-valve 200-hp Lycoming IO-360. Most planes are going to have some version of the parallel-valve 180-hp O-360 Lycoming engine, with many newer planes having fuel injection. This basic engine seems to represent the best compromise of price, power and weight. You may also see Superior and ECI (now Continental) versions of the Lycoming design. All of these engines represent good value to the potential buyer if they have been well maintained.

The RV-7 will accommodate a wide range of engine choices from 150 to 200 hp. This one is powered by an Aero Sport Power 195-hp IO-375.

Engines other than Lycoming-type engines detract from the value of the plane. If you find a plane with a Subaru or Mazda engine conversion, you should expect to pay way less for it, say $40,000 less or so, than if it were Lycoming equipped. Because of the problems these engines had, most have been replaced by now, but beware if you find one that hasn’t. That does not mean that there are not people who enjoy their alternative engines, but the marketplace has spoken, and it says planes with these engines are less desirable.

Of course, the O-320-series Lycoming engines are another choice, but expect to lose something in cruise and climb performance with the lower power output of these engines. On the plus side, they are very economical to operate and also a bit lighter.

You are much more likely to find a constant-speed prop on a used RV-7 than on an RV-6. Metal props, almost exclusively by Hartzell, are fairly common. There are also a few metal fixed-pitch props, mostly by Sensenich, that may be found on lower priced models. Newer versions may sport ground-adjustable composite props by Sensenich or WhirlWind to name two, or composite constant-speed props by MT, Hartzell and WhirlWind. There are also at least a few fixed-composite props out there by Catto and others. Be aware that light props may shift the center of gravity more rearward than you would like, limiting baggage carrying capacity. Be sure to check weight and balance before you buy.

Although it’s used primarily for $100 hamburgers or, more accurately, $100 fish sandwiches, Krea Ellis’ award-winning RV-7A features a beautiful interior and a full IFR panel.

Typical Avionics

Early RV-7s will likely have steam gauges and VOR receivers in their panels, but those completed more recently will usually have glass panels by Dynon, AFS or Garmin, with a few Grand Rapids and others rounding out the field. Many may have round instruments as backups to the glass, but the more recent ones will most likely have electronic backups such as the Garmin G5. These later versions also may not have any VOR capability at all, relying exclusively on GPS navigation.

Dave Harris’ RV-7A has a full suite of Dynon avionics and full IFR capability including a two-axis autopilot. These types of panels are showing up more and more in RV-7s.

The big question to ask yourself as a buyer is, do I need IFR capability? Many very nice panels do not have approach-approved GPS and are therefore not going to work for IFR flight. Do not be fooled by fancy displays. Make sure you have IFR-approved navigation equipment if you need it. It is expensive to add later. Backup systems are also very important to instrument pilots. Be sure you understand what you are getting when you consider your purchase. The good news is that there are quite a few IFR-capable planes that have been built, so you should be able to find one to suit your needs. The bad news is that these fancy panels add cost and bump up the selling price, pushing many well-equipped RV-7s above $150,000 on the used airplane market.

Paul Kovalak’s nice dual-screen panel relies on an older Garmin GNS 430 for navigation and communication. New, better-priced offerings from Garmin have largely eliminated the cost advantage of using older equipment such as this.

Common Modifications

One modification that many RV builders have embraced is a plenum in lieu of baffle seals in the engine compartment. A well-built plenum does a great job of forcing cooling air through the engine with virtually no leakage. Their downside is that they must be removed to service spark plugs. All things considered, I would consider a plenum a plus.

AntiSplatAero sells a number of popular mods for the RV-7 and other Van’s models. Visit their website for the complete rundown. Many builders and owners have added one or more of these items to their RV-7. I have come across a few other modifications that seemed to be practical. There can be a tendency, however, to load a plane up with a lot of minor mods and gadgets that mostly add weight and complexity, neither of which is desirable.

Like most of their models, Van’s designed the RV-7 to be sporty but also capable of cross-country flight.

Performance and Flying Qualities

As with most of their models, Van’s designed the RV-7 to be sporty but also capable of cross-country flight. This compromise means they are well suited for what you might call gentlemen’s aerobatics but still stable enough to fly a few hundred miles or more on a longer flight. The downside of this compromise is that they are not the most stable IFR platform without autopilot assistance. This is not your Cessna 172 or Piper Cherokee. If you want something that is as stable as a one-ton truck and holds 150 pounds of luggage, you should be looking somewhere else. But that seems to be just fine with over 10,000 RV owners.

The bigger complaint I hear is that RV owners who go back and fly a Cessna or Piper say they can’t believe what dogs those planes feel like compared to how they remember them. Compared to these planes, the RV-7 and other Van’s models have controls that are light and responsive, with handling that makes you feel really connected to the plane. The flip side of that is there is a sacrifice in stability inherent in the light and responsive feel.

Engine cooling plenums, like this one on Paul Kovalak’s RV-7A, are an effective way to reduce cylinder head temperatures in warmer climates.

Resources

By far the largest and most active user group in Experimental aviation is the Van’s Air Force forum. It is a tremendous source of information—and occasionally misinformation—about all things Van’s and RV airplanes. There is even a section devoted exclusively to the RV-7/7A. The Van’s factory does a great job of making service information and parts available on its website, which is often utilized by non-RV builders such as myself. Van’s also has live technical support by phone during limited hours, but many builder problems can be solved on the forum or by a search of its archives.

Prices

Prices of RV-7 models are on average quite a bit higher than for RV-6s. The planes tend to be newer and better equipped, which drives the price upwards as it should. The low end of the RV-7 price range seems to be in the mid-$80,000s. Depending on the engine, prop and avionics, the high end will be upwards of $150,000 or more. A recent look at Trade-a-Plane and Barnstormers.com showed several examples in the $120–140,000 range. If you are looking for something with a constant-speed prop, a 180-hp fuel-injected engine and dual-screen IFR avionics, you will have to pay a good price for it. You can always upgrade a less-well-equipped model, but it is generally cheaper to buy the best plane you can afford and take advantage of the other guy’s efforts.

Calendar age isn’t a big factor for the airframe value, but years of little or no flying should raise a caution flag, especially as it relates to engine condition. Inactivity is often not kind to airplanes. A careful prebuy inspection is always vitally important before any such purchase.

The RV-7 and -7A represent a very good value for an airplane that serves most people’s needs very well. They can be a little tight on space for big guys and do not hold a great deal of baggage, but there’s a reason over 1800 of them are flying and many more are under construction.

Owner Feedback

Jeff KerseyI bought a flying RV-7A in February 2016. I had been flying for 13 years but always just rented what fit my mission for the day. Two miles from my house is a private airstrip that belonged to a good friend. He was getting near the end of his life and asked me to help him sell his Cessna 172. I delivered it to the new owners in South Texas. A couple weeks later he told me if I bought a plane, I could keep it there for free. All of the sudden, owning an airplane got much more interesting. I did not really know about Experimentals or Van’s Aircraft. I started reading about them and could not believe the performance numbers. I searched out an owner locally who had an RV-6A, and he was generous to give me an introduction. As soon as we took off and started climbing, I wanted one. Side-by-side was my preference as my wife would not want to sit in back, and I like to share the experience with friends and other pilots. A slider was also my preference for staying cool while taxiing out in the summertime. I went to look at a few planes and passed on the first one, a nice RV-9A, because I was not comfortable buying the first plane I looked at. By the time I realized it was a good one, it was gone. Passing through an airport in North Carolina, I happened to find an RV-7A that was not listed. It only had 52 hours on it. The owner passed away and the family was selling it. We agreed on a price and I flew back down after a condition inspection by a local mechanic. It is not a show plane but the high-ticket items, engine and avionics, were fairly new. I now have 500 hours on it and I love it. I say, “It is not a show plane, it is a go plane.” And it’s mine. It is a magic carpet. I have been to more family events in the last four years than the previous 30 years. I also use it for business trips and have spent more nights at home in my bed because of it. If it is within 1000 miles, it is faster and cheaper than the airlines door to door for me and my wife—most of the time. I have the RV grin!

Krea Ellis – We purchased the kit as a project in 2017 from an owner in Grand Junction, Colorado. First flight was in March 2018. We took the airplane to Evoke Aviation in Gadsden, Alabama, and the incredible paint scheme, a collaboration between my son and Plane Schemer, was completed about a week before OSH. We still had 25 hours of Phase I to complete, but made it to OSH on the first Sunday and were thrilled to win an Outstanding Workmanship award. The airplane is a delight to fly. Handling qualities are excellent. We’ve done very limited aerobatics, but will test and expand the envelope once we get some competent aerobatic training. Mostly we like the fact that we built it ourselves. We primarily use it for $100 hamburgers or, more accurately, $100 fish sandwiches in Destin, Florida. The airplane is equipped with a parallel-valve Titan IO-360 and Hartzell wide-chord composite prop. It’s a great combination and the prop is very tolerant of our less than ideal runway conditions at Mallards Landing (GA04). We have a full Garmin IFR panel built by SteinAir. The airplane is great for just burning 100LL and despite what some say, it works just fine for IFR flying, too. Would I do it again? Yes, but differently. I wouldn’t buy an existing project (too many unknowns and mistakes) and it would be an RV-14 instead of an RV-7. Much more refined kit, easier to build and more capable for how we use the plane.

Jason Johnson – So yes, the RV grin is for real! My airplane definitely exceeded my expectations and meets or exceeds published performance numbers. I have flown 154 hours since the first flight on January 3, 2020. What do I like about my RV-7? Everything! I always said I would build an RV-8, but I felt that the -7 offered a little better package in the way of available baggage space, weight and balance, and a better experience for the passenger. No regrets with this decision. My wife loves this airplane and can’t wait to go flying, often participating or riding along during formation or aerobatics. She is learning to fly in our Cherokee and is hoping to fly the RV. It’s fast and feels very balanced and controllable throughout the envelope. It’s very predictable and an easy tailwheel airplane with seemingly no bad habits. The RV community is amazing—I’ve flown 154 hours and probably made at least that many new friends. Just Awesome! We are doing lots of formation and aerobatics and have a lot of cross-country trips planned. We want to hit every state and national park with the airplane. I am also a corporate pilot and sometimes use the -7 to commute to other airports for a trip. Maintenance issues have been minimal, limited to a very minor oil leak and a cracked exhaust hanger. Both were quickly repaired. Luckily, all my engine temps and cooling are great, so I can truly climb VX/VY without temperature limitations.

Alan Dyck I now have 375 hours on my RV-7. Like all Van’s aircraft, it is an awesome plane to fly. Mine stalls at 48 knots indicated with a top speed of 178 knots. My typical cruise is between 2300–2400 rpm at 145–150 knots. Prior to the -7, I purchased an RV-4 to learn to fly a taildragger since I had no tailwheel time. I put 450 hours on the- 4 in the four years I had it. The -7 is nicer in that it has more room, no weight and balance concerns with a passenger and baggage, and it has more range. The things I miss about the -4 are the centerline seating and the agility. Both are great planes! I had one major engine issue with it making metal after 34 hours. The engine was pulled and it was found that the overhauled tappets had not been properly done and had destroyed the cam. The engine was again rebuilt with new cylinders, pistons, cam, lifters, oil filter and cooler, oil pump and gaskets. Everything has been OK since. I tried a Rotec TBI for the first 100 hours but it ran too lean at WOT. I couldn’t get support from Rotec to solve the problem, so I changed to an MA4-5 carb with the Mooney mod, which has worked great. The plane just requires normal maintenance with no other issues to date.

Jim HarrisI purchased my RV-7A from the builder in April 2015 and I’m now completing my fifth year of ownership. This is the only aircraft I’ve ever owned, and I purchased it because I had just gotten back into flying after a 22+ year layoff as a military pilot. The price I paid reflected a prop strike by the original owner the summer before I purchased it. The aircraft had approximately 170 hours TT when it experienced a prop strike going to AirVenture. The engine was removed, torn down and thoroughly inspected by G&N Aircraft according to Lycoming standards, with new magnetos, rings, bearings, seals, etc. installed during the inspection. A new Hartzell constant-speed prop was installed. I had a relatively high degree of confidence in the effectively new engine and prop. Mistakes were made during my prebuy experience, transition training and first year and a half of ownership. However, my overall experience is extremely favorable. Once I figured out that every used aircraft has issues that need to be addressed, with E/A-B aircraft needing particular attention to build quality, my appreciation of the aircraft grew. I’ve had four different A&P/IAs (three of them with significant RV/Experimental aircraft experience) work on the aircraft and assist with the annual condition inspection. Each one discovered different issues they thought needed attention—and each item was addressed. I love flying the aircraft. Learning piston engine management and how to work on it has also been very enjoyable. Dusting off 22+ years of pilot rust has also been interesting, and I’ve survived a few unexpected surprises.

Rick Weiss – In the years since first getting that magic ticket to fly, we would rent whatever we could afford at the time and do day trips and little overnight mini-vacations. We had a blast! She loved visiting places and I loved flying us there. But when we weren’t going someplace, I still wanted to fly. The problem was, the local 172 just didn’t satisfy my inner Walter Mitty. I imagined myself a fighter pilot wrenching a plane through the sky, doing loops and rolls, then sliding into position on my flight leader for the trip home. When it came down to it, I wanted it all. Unfortunately, I wanted it on a budget. So, I started the research. At some point in this process, I started to become aware of another path: a homebuilt aircraft. I started to compile a list of potential aircraft that could meet my priorities. I wanted something that could be built mostly by myself in my garage, would meet the major mission goals (IFR cross-country and aerobatic), could be built in a couple of years and would be cost-effective. When the analysis was done, a couple of potentials bubbled to the top. But because my wife is very sensitive to the smell of resin, it came down to one: the Van’s RV-7. There has been a lot written about Van’s aircraft; I will add my voice. It’s a fine airplane that really is a jack of all trades and master of fun! Since completing my RV-7 in November 2017, my wife and I have been all over the western half of the United States. And in between trips, I get to exercise that inner Walter Mitty and play fighter pilot. I have even recently started formation flying. I love this plane!

James JulaMy RV-7A has been flying for four and a half years, with the Hobbs meter now approaching 300 hours. It is so worth the 13 years I spent on and off building the slow-build kit. I remember one flight where I was passing over Crater Lake in Oregon around 11,000 feet, near sunset with the light shining off the rivet line of the wing. I realized I had riveted every one of those rivets so I could be in that very spot. Incredibly rewarding! When I think about what I like about my plane, I ask: What other plane is there that can fly at night, IFR and go upside down regularly? It is nimble and well balanced, easy to fly, cruises at a good speed, can fly slow enough for shorter runways and was built exactly how I wanted it. The view out of the tip-up canopy is amazing, especially during loops as you come over the top and see the earth coming back at you upside down. I have to say that flying other non-aerobatic planes just doesn’t compare anymore. If there are any negatives, it is a touch on the smaller side, but some sacrifices are needed to keep it fast and strong enough for aerobatics while keeping it more affordable to fly. It would be a more difficult decision today to choose between building a -7 or a -14. While the -14 is roomier, it is a bit more costly, too.

Tim Threw – The Experimental aircraft world was always interesting to me. I liked the idea that a person could have lower ownership costs if they were mechanically inclined and liked working on machines—which I am and do. I briefly considered building, but I was approaching 60 years old; I wanted to be flying, not building. I started researching on the web: KITPLANES®, Van’s Air Force forums and builder and company sites. Extending my search, I found an RV-7A that was a good match. Deposit check sent, I flew commercial to Burbank, California. After a flight and prebuy inspection at the owner/builder’s hangar at Fox Field on a hot late-July day, I was the new, proud owner of N54LH. The next morning, I was flying back to central Illinois—and I had the RV grin. I “adopted” my RV-7A in July 2015. I have about 700 total hours, 450 of those in my RV. The hardest part I had transitioning from spam cans was overcontrolling on landing and landing too flat. As I was told during training, “Think of the nosewheel as a bike kickstand; only use it when you have to.” Both issues I have overcome. I like to tell people that I found the RV “twitchy” at first—but now it is responsive—and I love how it handles. N54LH is a great traveling machine. My wife and I are both small, so we fit just fine and can carry full fuel and still have plenty of weight capacity for our bags. We have flown with a group of five other RVs from Minneapolis to Kalispell, Montana; Seattle; and Northern California—a wonderful experience. We’ve made several trips to New Orleans; Destin, Florida; and Dallas. And we’ve been to Sun ’n Fun once and made three trips to OSH (another fantastic experience). Would I do it again? Absolutely. Any regrets? I wish I had done it sooner.

  1. N98DA has 1297.8 hours on it after I certificated it in 2007. I flew it twice this year from Manassas, VA to Pearson Field, Vancouver, WA. On average, the round trip took 29.9 hours of flying. On the last return flight, I took off in 1.25 miles visibility and 300 feet VV at 1053am, and arrived at Manassas at 320pm the next day. This took three fuel stops and two of the four legs were under IFR. Average fuel burn for both xctry trips was 8.7gph on my O-360. I cruise at 166 knots TAS at 8,000ft, running 24 squared. If you train regularly, IFR flight is no different than in another ASEL; as with any airplane, an autopilot is essential.
