Eichenfeldt line drawing (1910 Aeronautics)
Biplanes c.1909 = Plural use of the model refers to a bowed wing attached at the tips to a high-wing mainplane covered with sheet aluminum. Unusually streamlined for its day, the fuselage appears as cabinlike, except for open windows. Unknown motor type. 1909 Jane's comments: "Put on the market by H J Nice & Co; price about $1,000. Several are building, but none completed yet. Models have been very successful, and remarkably stable."

Aerobat I c.1937 = 2pOM flying wing; 50hp Continental; span: 24'0" length: 17'0" v: 95/75/38. [NX17638].
Aerobat "Bat 1" was a tractor-engine aircraft, a tail-dragger with widely-spaced retractable landing gear that appeared to fold outward into the bottom of the wing. Tailwheel extended behind the rudder pivot line. Most of the aircraft is wing, but the forward fuselage containing the engine extended in front of the wing and was aligned below the leading edge of the wing, with the engine centerline below the wing leading edge. The aircraft had a reverse-delta wing planform with the slightly-tapered leading edge of the wing starting just ahead of the framed bubble canopy. The leading edge went out to rounded wingtips. Trailing edge of the wing tapered from the wingtips all the way back to the rudder hinge line at the aft end of the fuselage. There was a single vertical tail with the stabilizer mounted at the top, and small teardrop-shaped tip plates on the tips of the stabilizer. ( Michael Morrow 4/5/07)
Aerobat II, III - No data for follow-up models, which apparently were redesigns and rebuilds of the original, retaining its license. III had a tail-mounted pusher engine [N17638]Eichmann died in its maiden flight on 7/20/97 when oscillation caused elevator failure and a crash on take-off at Brownsville.

EC-3 Airmobile 1929 = Shown in the plans section of the 1929 Aircraft Yearbook, this was huge, high-wing monoplane with the pilot in an open cockpit behind the wing, and with a cabin for perhaps four to six passengers. Elias has presented many problems for researchers, and this is another of them: (1) the big radial engine shown in the three-view belies its description of a "Liberty;" (2) the model merger of the EC line of small, low-powered sportplanes with the Airmobile biplane is odd; (3) no dimensions are shown, but it seems to be in the general size of the 1927 Airmobile biplane. It was undoubtedly never built.

Soon after it was flown to Haiti via Key West and Cuba by Middlebrook and partner, John Ackerman, refueling along the way from five-gallon cans of gas carried in the cockpits. The original plan was to start an air service in Haiti; however, because of heavy taxation and other troubles with the locals, they flew back to NY. There Ackerman bought it, flew it back to the west coast, and sold it. Middlebrook became a flight instructor at Pensacola in WW2 and founded Penn Yan Aero in 1945.( Bill Middlebrook 3/17/05)

English line drawing
1908 = This father-and-son team built a full-size 1p helicopter with 60hp Hall-Scott V-8, and two hinged 16' rotors mounted on a triangular, steel-tube platforma primitive VTOL concept. "Planes" indicated in the linked drawing are curiously shaped, unexplained, and do not show up in a photo that appeared in 1909 Jane's. Not only that, but that craft looked entirely different from this side-view sketch in 1908 Jane's, which shows a quad-gear cart with sulky wheels under a frame with two circular helical rotor-forms fore and aft, and no rudder. The only thing in common with the two is an identical report that during an unmanned full-power trial in a shed, in July 1909, it broke its tethers and ambitiously smashed itself into the ceiling. Technically it did fly, but in which of its forms is unknown.

ERCO 191-A [X16796] (SEE comments below)
191-A 1936 = 2pClwM; 285hp Jacobs L-5. Enigmatic first production with very little data. Somewhat of a Harlow look to it. Design credit reported as "Don Berliner"a misprint, or was Don Berlin involved? POP: 1 [X16796].
ERCO 191-A is a real challenge. The only register note I found is in Weekly List, Vol 8 No 21, 10/3-16/36: "*X-16796 Engineering & Research Corp, 6100 Sligo Mill Rd, NE Washington DC; Engineering & Research 191A, 2PCLM, 191A-1, '36, Jacobs L-5 285hp. Expires 3/1/37." The asterisk indicated that the plane had never been licensed or identified before.
The picture, possibly that 191-A, is from Vintage Airplane Jan 1993, with accompanying text: "The Mystery Plane remains somewhat of a mystery. The photo appeared in Ken Beatty's book, Cradle of American Aviation, an account of the history of College Park airport outside of Washington DC." The caption with the photo credited its design to the company that "built the Ercoupe," with Don Berliner as designer. No confirmation of this claim has been found. Don Berliner must be a misprint. They can't possibly mean Don Berlin, who was "director, aircraft development section, Fisher Body Division, General Motors Corp 1934-42" (Who's Who in World Aviation 1955). So it comes back to Henry Berlinerdid he have "Don" as a nickname?
Henry Berliner organized ERCO in 1934 in DC to produce aircraft production machinery (AAHS Journal Spring 1985). ERCO was situated in notheast DC, and College Park lies just outside northeast DC. Everything fits, except in Fred Weick's memoirs, he says: "Up to 1936 ERCO had never been involved per se in building airplanes." ( Lennart Johnsson 1/30/99)

Despite being a credible, safe, spinproof, and easy-to-fly airplane, Ercoupe never gained deserved popularity because it was in fact too easy to flya threat to flight instructors?and was scoffed at by "real" pilots for not having a conventional control system. Yet thousands were sold, even at such notable non-aviation outlets as the men's department at Macy's, and an entirely new category of CAA license was created for thousands of new pilots who never felt a rudder pedal.
Ercoupe Retractable gear (magazine clip)
A prototype with retractable gear was built in 1946 and flown with a bigger (c.130hp) engine [N93541]. Certification never happened, and sources claim it was probably flying under (718). There was also a 4-5p Ercoach in development, featuring dual fuel-injected engines built flush into the wings. Planned, as well, was a pusher with retractable gear and an Ercoupelike dual tail. Rumors have it that an unfinished prototype was found in the 1990s and was finished as flyable.
415-C/D 1947 (ATC 718) = 2pClwM; 75hp Continental C-75; load: 510# v: 122/110/48 ceiling: 14,000 range: 450. Gross wt: 1260#. From $3,500; POP: 368. Introduced after ERCO decided that the D's 9° up-elevator travel limitation seriously affected landing qualities, so restored the elevator limit in the C, but left an option of converting the plane to a D.
415-D 1947 (ATC 787) = 2pClwM; 75hp Continental A-75; span: 30'0" length: 20'9" load: 595# v: 122/110/56 range: 450. Stainless steel front fuselage skin, larger baggage area, 9° up-elevator travel. Gross wt: 1400#. $3,590 (less optional crosswind gear, lights, radio, starter, and generator); POP: about 75.
415-E, -F 1948 (ATC 787) = 2pClwM; 85hp Continental C-85; load: 586# v: 127/114/56 ceiling: 12,500'. New Split elevator kept flying characteristics of 415-C. 20° up-elevator travel. 415-F had fuel injection. $3,995; POP: 127.
415-G, Clubair 1949 (ATC 787) = 2pClwM; 85hp Continental C-85; load: 562# v: 125/110/56 range: 450 ceiling: 11,000'. Deluxe 415 with generator, starter, lights, radio; larger baggage area; bubble windshield. 415-G featured a "Kiddy-Seat." Two- or three-control systemoptional rudder pedals were more psychological than practical. $3,950; POP: less than 140.
415-H 1949 (ATC 718) = 75hp Continental C-75; load: 460# v: 120/105/56 ceiling: 14,000'. Gross wt: 1260#. No electrical system. POP: 7. Total all 415 models 1940-41 and 1947-52: 5,140 (?> some sources show 5,028 including production by Sanders, or 5,685 including subsequent production by Alon, Forney, and Mooney).
Ercoupe XPQ-13 Hardin restoration [N37143] (Harry L Francis)
Ercoupe XPQ-13 Faster than a speeding Air-Knocker! [N28655] (Air Force Assn)
PQ-13, O-55 1941 = USAAC for planned use as aerial target; specs similar to pre-war 415-C, but with O-300. POP: 3 initially as YO-55. [41-18875], with YO-170-3, was received by the USAAC on 2/26/41. More auspicious, the first Jet Assisted Take-off airplane was a 1941 65hp Ercoupe [NC28655] s/n 11 (?>[N2049H] s/n 2673), designated as XPQ-13 (p: Lt Homer Bushey, at March Field CA). Those tests led to widespread use of JATO during WW2, as well as the foundation of Jet Propulsion Laboratory. A black powder burn released 174# of thrust for 12 seconds. The first burn tests were conducted at 6000', then followed a series of tests at take-off that provided spectacular results. JATO cut the take-off distance in half in all weight configurations. That aircraft reportedly was still active in San Rafael CA at this writing.
The JATO Ercoupe has been the subject of much debate and folklore. The real rocket-powered Ercoupe, [NC28655] s/n 11, can be verified by looking at the photos in Stanley G Thomas' 1991 book, The Ercoupe, page 66. The photo was taken in Aug 1941 and is from Cal Tech archives. That Ercoupe was built on 12/4/40 and sold to USAAC on 1/4/41 for $10.00, delivered to AAC Material Division, Wright Field OH. I have the FAA files to substantiate this information. ([N28655] now belongs to a Grumman aircraft.)
The first military Ercoupe, about which I know more than the other two, is my [N37143] s/n 110, acquired on 8/19/41 as the last PQ-13 purchased by the USAAC [41-25196], delivered to Wright Field and officially entered into inventory on 12/8/41 as one of two PQ-13's submitted to compete for the Aerial Target Contract, which Al Mooney's PQ-14 subsequently won. According to numerous books written about the Ercoupe, s/n 110 was the very last production model produced before the outbreak of WW2. S/ns 111 and 112 were built in 1942 from spare parts. S/n 112 is documented to have flown with the Civil Air Patrol in WW2. The fate of the other XPQ-13 ( ed: [41-39099]) is of some mysteryone report claims that it went down off the New Jersey coast in WW2.
I inquired to FAA if s/n 11 had been issued a different N-number after the war, and the answer was negative. The last activity of record on that aircraft was 2/3/42. A letter from CAA to USAAC stated that [NC28655] and [NC37143] had been taken over by the Air Corps, that the planes had been canceled on CAA records, and that airworthiness certificates and operation records issued by the CAA inspector were void and should be returned to their office.
There is some debate about the rocket-powered Ercoupe being designated as YO-55. The JATO Ercoupe did not have an official flight record as that was a top secret program at the time. USAF Historical Society as of 6/20/2000 assumes (until we can find more paperwork) that the rocket-powered Ercoupe and the YO-55 were one and the same. However, according to YO-55's flight records, no indication exists that it ever went to March Field. We have paperwork on two of the three actual military Ercoupes as recognized by FAA, USAF, and USAF Historical Society. ( Mark Hardin, Terrell TX)

Twin Ercoupe [NX93384] (1948 Flying via Charles Garrison)
Twin Ercoupe Derelict
Twin Ercoupe c.1948 = Two 415 fuselages joined much like the North American P-82, for use air shows. It had conventional controls and could be flown from either unit; v: 140/100/75. (Thanks to Eut Tileston for steering us to Pete Bowers' photo! 2/2/03)
The twin Ercoupe was built by J B Collie, Southeast Air Service, for the Thrasher Brothers Air Circus, Elberton GA. It was flown by Grady Thrasher and his brother, who rolled, looped, and spun it (yes, it would spin!) They also featured landing a J-3 Cub on a platform mounted on a Ford convertible. Grady lived in Huntsville (AL) from the mid-'70s until his death a few years agohis stories were fantastic and I really enjoyed them, but will not quote for fear of getting them wrong.

(W Samuel) Evans Aircraft, La Jolla CA.
VP-1 c.1968 = 1pOlwM; 40-60hp Volkswagen; span: 24'0" length: 18'0" load:
310# v: x/75/40 (40hp). Initially called Volksplane. Ex-Convair engineer Evans' intention was to offer the novice home-builder an all-wood aircraft that was easy to build, and safe to fly. Evidently he succeeded, for 6,000 sets of plans for VP-1 and -2 had been sold by early 1982.
VP-2 c.1970 = 2pOlwM; 60-65hp Volkswagen; span: 27'0" length: 19'3" load: 400# v: 120/100/40. Larger, two-place side-by-side version of -1.

All-metal construction, tandem seats, tapered wing with the Midget Mustand airfoil, tail from a Comanche 250, Mooney-type tri-gear. Fuel was kerosene or #1 diesel. POP: 1 [N64TT] c/n 1. Planned production naver came about and the ship, while reportedly flying in tests with good stability and performance, never accumulated its 40-hour requirements for certification and was listed for sale as-is in 2007.

Sportsman c1975 = 1pOB; 180hp Lycoming; span: 20'1" length: 16'10".
George Exel, Clifton NJ.
#1 1920 = 1pOH; 50hp Gnôme; rotors: 21'6". Empty wt: 654#. Two-blade coaxial rotors. In tests the helicopter was barely able to hover without the pilot on board, and the control system proved ineffective.
#2 1923 = 1pOH; 80hp LeRhône; rotor 24'0". Co-rotor system. "The co-rotor system refers to the idea of reacting shaft torque of an engine-driven propeller or screw by the crankcase [of the rotary engine], to which the reacting rotor is attached. In Exel's arrangement the crankcase drives the lifting screw [propeller] while the otherwise stationary shaft of the rotary drives the rotor in counter-rotation." Propeller diameter was 8'4". Tests were conducted indoors in 1923. With full throttle and the operator standing beside the machine, it barely lifted one wheel off the ground.
#3 1925 = 1pOH; 80hp LeRhône. Rebuild of #2. An intermediate rotor was introduced making it a "triaxial" machine because of its three rotating members. A new, 6' lifting screw was used, while that of the two-blade intermediate rotor was 14'. The latter included in its hub a planetary gearbox. In tests this variant was able to lift off the ground, but the control system proved to be of little use.
#4 1926 = 1pOH; 110hp LeRhône. A modified version of #3. The intermediate two-blade rotor was replaced by a 16' four-blade rotor. Thrust was improved, but not controllability. Destroyed in a windstorm in late 1926.
#5 1930 = 1pOH; 110hp LeRhône; upper rotor: 9'6" lower rotor: 34'0". A co-rotor design. For the first time a method of cyclic control was introduced, using ailerons on the main rotor blades. A swashplate accounted for both cyclic and collective control of the main rotor, which was of a more modern high-aspect ratio type. Tests showed the rotor to be responsive to the cyclic and collective system used; however, vibration was excessive, and the machine was incapable of hovering. Exel then paused in helicopter research until after WW2.
Model 100 1946 = Conventional tail-rotor helicopter with swashplate controls, flown about 70 hours; 100hp Franklin. No specs found. War surplus Platt-LePage rotors. It was reported that Exel built his seventh and last helicopter in 1967 at age 74.
