American Champion 7EC Champ


Ladies and gentlemen, now entering the ring, wearing any of 20 colors, weighing 1,320 pounds, from Rochester, Wisconsin...the Champ! Florida dealer Larry Tague even paints boxing gloves on the tail. The American Champion 7EC Champ — certified under the old CAR 4 rules — is re-entering the market as a light sport aircraft, and thus has a 1,320-pound gross weight limitation. To take the title of best-selling light sport aircraft, it must compete with 40 light sport aircraft including two Cubs that, like the Champ, appeal to the same tailwheel nostalgia market.

Is it really a Champ?

But, you say, the Champ was the 7AC and had a cartoon-like bulbous windscreen and a sliding window. You'll find neither of these features on the new Champ, so is it really a Champ? Originally the Champ included Aeronca's 7AC, 7BC (military L-16), and 7CC (Continental 90-horsepower C90 engine) and was built from 1945 to 1949. The 7DC (Continental C85 engine) and, yes, the 7EC with the Continental C90 engine — were the last Champs produced by Aeronca before it ended production in 1951. Then came the Champion Company, which resumed production of the 7EC Champ in 1955, according to Robert Szego, president of the Aeronca Aviators Club and the Bellanca-Champion Club. "Then began the magic journey with [the] 7FC that had a nosewheel, the 135- to 150-horsepower 7GC, the 7HC, and the 7JC with its strange tailwheel setup. These were all Champs," Szego said.

Ah, but what about the 100-horsepower engine on today's 7EC? Wasn't the 7EC a 90-horsepower airplane, you ask? In 1964 Champion Aircraft certified it with a 100-horsepower Continental O-200 — setting the stage for the return of the Champ.

The model number and the engine are the same, but that is where the similarity stops. The tail, nose cowling, and fuselage sides are like the original Champ series, but the windows, interior, door, and windscreen are those of a modern Citabria that first appeared on the scene in 1964. The right wing is like that of today's 7ECA (now called the Citabria Aurora) because it has an 18-gallon wing tank, but the left wing is like that of the 7EC (identical to a Citabria wing) but without a fuel tank. To save weight, the aircraft carries only 18 gallons of fuel — 17 usable. The Citabria-like aluminum landing gear — which Szego says is easier to maintain — did not need to be as heavy and robust as the gear used on the Citabria. "There are the [Champ] purists who do not appreciate the squared-off wingtips and rear windows, and the spring gear [of the new Champ]," Szego said. (It does, however, have a wooden propeller.)

"There are very few new Champs out in the field so far, but the few people that flew them are very satisfied. The big item is the fact that you can actually buy a new Champ, something that hasn't been available since the Citabria came out in 1964," Szego added.

How does it fly?

Except for the power difference it flies much like the 118-horsepower Citabria Aurora and the 160-horsepower Citabria Adventure. The aircraft is docile during stalls — and even when held in the stall it reluctantly drops a wing. The pilot's operating handbook says the aircraft will lose only 100 feet in a stall. Holding altitude was not difficult during steep turns, and, partly because of the excellent visibility, the flare during three-point landings was easily gauged.

The airframe is approved for plus 5 and minus 2 Gs, but you can't do aerobatics — like a loop — despite the impressive numbers. Aerobatic maneuvers are limited to spins in the utility category. To fly in that category you primarily ensure there is no baggage in the baggage compartment.

During a brief evaluation flight from Orlando Sanford International Airport there was time to conduct a true-airspeed test: The result was 81 KTAS, a few knots slower than the 87 KTAS reported by the factory. It was a hot July morning in Florida at only 1,800 feet msl. A busy traffic pattern required the tower to limit Tague and me to two landings (both three-pointers), but they were enough to prove the new Champ continues the company's tradition of building tailwheel aircraft that are easy to land.

The pilot's operating handbook says the fuel burn is 6.8 gph based on data from the engine manufacturer, but both the dealer and the factory offer a spirited argument that they have flown the model on long delivery flights burning only 5.9 gph...6, tops.

What's not to like?

The payload with full fuel is the aircraft's biggest drawback, but many of the early customers seem not to mind since they mostly fly alone. With full fuel this is an adult-plus-child aircraft, and with half-full tanks both occupants must watch their diets. To provide a greater margin during the flight to Florida's east coast from Sanford for photos with this article, only one smallish pilot per airplane and full fuel was allowed.

Jerry Mehlhaff, president of American Champion, has lots of plans to improve the payload. He is hoping Continental will complete certification of its new O-200-D light sport engine this winter, which is lighter than the current O-200-A. Cessna is using the O-200-D in its SkyCatcher. Mehlhaff could use lighter tires, a lighter tailwheel, and a lighter interior — he hopes the result will be a Champ of less than 900 pounds empty weight — a 50- to 70-pound improvement over the present one. You can't take out the floor carpet because there isn't any. Floors are mahogany-stained five-ply birch panels.

What's the alternative?

Buy used. There are still more than 2,600 of the 7AC Champs on the FAA registry, and American Champion's Mehlhaff estimates the average cost for one in good shape to be $35,000. (Szego estimates more than half of those are flying.) The other four Champ models show only 150 to 200 aircraft still on the registry for each model, so chances are good that you will end up with a 7AC.

Jim Leavitt of Sanford, Florida, found quite a deal when he went shopping for a Champ in 1999: a Champ in apparently good condition with only 50 hours on an overhauled engine for $12,500. He flies 50 hours a year. The airplane provided him with fun for two or three years, and then an airworthiness directive on wooden wing spars called for an inspection. (New ones now have metal wing spars.)

As long as he was inspecting the wing spars, Leavitt decided he might as well replace the fabric. He went to Southern Aviation Services, which not only specializes in tube and fabric work, but is located at Bob White Field (X61) northwest of Orlando, where Leavitt bases his aircraft. Bob White Field features an exquisitely kept grass runway — perfect for tailwheel airplanes. (Also tied down there is serial number 1 of the pre-World War II Piper Cub J-4 line.)

Re-covering led to the discovery of mouse nests in the leading edge, and mouse urine had done its damage. Also, a wingtip was out of specification and had to be reworked. The final bill after the airplane was repaired, covered with new fabric, and painted came to $13,000.

Performance? You're not really looking for performance if you are a Champ owner — you are looking for fun. That said, he cruises at between 80 and 85 mph true airspeed (70 to 74 KTAS). His climb and landing approach speeds are both 60 mph, and he slows to 70 mph on downwind.

It's a sweetheart of an airplane," Leavitt said. "I never go above 1,000 feet and fly outside of airspace where radios are needed. It's not a mission airplane. Its mission is having fun." That can be said of the new Champ, as well.\

Performance Summary

The Champ is a single-engine, tandem two-place, strut-braced, high-wing airplane equipped with conventional landing gear.

This airplane is certificated in the normal and utility categories. See the airplane’s P.O.H. for approved maneuvers. The airplane is approved for day and night VFR operations when equipped in accordance with F.A.R. 91 or F.A.R 135.

The airplane is powered by a horizontally opposed, four cylinder, direct drive, normally aspirated, air cooled, carburetor equipped engine. The engine is a Continental Model O-200-A and is rated at 100 horsepower.

An 18-gallon, welded aluminum, fuel tank is located in the inboard section of the right wing. The fuel system is a gravity flow type system. Fuel quantity is read from mechanical float type gauges located in the fuel tank. The gauge is only accurate in level flight attitude.

The electrical system is powered by a 60 amp alternator and a drycell, 12 volt battery.
