Waco F series / INF / KNF / MNF / RNF / PCF / PBF / QCF / UBF / UMF / UPF-7 / PT-14 / YMF / ZK-7 / ZPF / XJW-1 / YPF / QNF / CPF / DPF / EPF / VPF
The Waco ‘F’ series of biplanes supplanted and then replaced the earlier ‘O’ series of 1927/33. The ‘F’ series had an airframe which was smaller and about 450 pounds (200 kg) lighter than the ‘O’ series, while continuing to provide accommodation for three persons in tandem open cockpits. A similar performance to the earlier model was obtained on the power of smaller and more economical engines.
The initial models were the INF (125 hp / 93 kW Kinner engine) with around 50 built, KNF (100 hp / 75 kW Kinner, about 20 built, ATC 313, at $3,630) and the RNF (110 hp / 82 kW Warner Scarab, nearly 150 built), all of which had externally braced tailwheel undercarriages. Many further sub-models followed with more powerful engines of up to 225 hp / 168 kW. The most powerful in the range was the ZPF of 1936/37, intended for executive use.
Only four 1931 MNF’s (ATC 393) were built; NC11213, NC11222, NC11239 and NC11246, priced at $4,475.
Al Menasco used the MNF to help promote his engines. A Heywood air-operated starter, caster action tail wheel, compass, navigation lights, first-aid kit and fire extinguisher were standard equipment on the MNF. NC11213 has the optional, Hamilton Standard ground adjustable prop. Brakes were optional.
The first QCF was finished on May 12, 1931. Thirty-one were built in 1932.
The ‘F’ series was popular with private owner pilots for sporting and other uses and continued in production through the late 1930s. The tandem cockpit UPF-7 was adopted by the Civilian Pilot Training Program and continued in production until 1942 by which time over 600 had been built.
One EPF-6 was built in 1936 and test-flown.
The 1936 VPF-6 was similar to the VPF-7 but with narrower landing gear and smaller wing cut-out. It was advertised as available, but none was produced. The 1937 VPF-7 (ATC 642) was the export version of the UPF-7. Priced at $9,500, six went to Guatemala, all of which returned to the US in 1959.
Two, 9521/9522, XJW-1 of 1934 were a USN version of the UBF as hook-up trainer and mail shuttle for the dirigible Macon.
In 1937 Waco introduced its Model UPF-7 as an open-cockpit biplane with a 164-kW (220-hp) Continental W-670-K radial engine and seating for two or three. The type was intended for training and sport use. A single example was evaluated by the USAAC as a primary trainer during 1939 with the designation XPT-14.
The 1939 XPT-14 39-702 crashed in testing on 11 October 1939.
Then followed 13 YPT-14 service trials aircraft, which were later re-designated PT-14.
A single civil 1937 Model UPF-7 (ATC 642) was impressed in 1941 with the designation PT-14A. However, another 600 aircraft of the same basic type were ordered, priced at $9,500, with three engine types for the Civilian Pilot Training Program that undertook pilot training at educational institutions to provide a pool of trained pilots in the event of war. Another 31 similar aircraft were bought by the Civil Aeronautics Authority for its own flying unit, and 14 to the USAAF as YPT-14.
One QNF model was built. It flew, but presented nose-heaviness problems.
The three place YPF-6 and YPF-7 OF 1935 (ATC 586) featured a sliding canopy and unit price of $8,395. Five were built as YPF-6 (NC15700, NC15606, NC15711, NC16579, NC17470) and three re-designated in 1937 as YPF-7 (NC17710, NC17715, NC20907).
Three ZPF-6 (ATC 586) were built in 1936, NC15707, NC16579, and NC17470, featuring a sliding canopy. The price was $7,385.
Two ZPF-7 were built in 1938, NC17710 and NC17715.
Approximately 600 came out of the Troy, Ohio factory between 1937 and 1942.
The WACO Aircraft Company of Ohio Inc had built three replicas by December 2011, which they designated MF.
Military operators
The Guatemalan Air Force received at least 1 Waco YMF-7 in 1934, which was still in airworthy condition in 1998.
The United States Army Air Corps adopted the UPF-7 as the PT-14, with one XPT-14 and 13 YPT-14s being purchased, with an additional UPF-7 impressed in 1942 as a PT-14A. Some were operated by the United States Navy.
The 1932 PBF (ATC 491) was priced at $4,415. Basically the same as PCF with modified ‘B’ wings. Four were built; NC13029, NC13049, NC13428, and NC13446.
Three 1931 PCF (ATC 453) were built; NC11476, NC11483, and NS12439, priced at $4,415. The PCF-2
(Certified ATC#473 2 October 1931) featured a new cross-braced undercarriage.
177 1930 Waco RNF were built (ATC 311, and 2-255 and 2-311) for weight changes. They were priced at $4,195-4,320, or $4,450 with an optional 125hp Warner engine.
Priced at $5,025, about 11 1932 Waco UBF and UBF-2 (ATC 473) were built, of which 2 went to the USN as XJW-1 dirigible “skyhooks”, and one was fitted with EDO floats in 1933; NC13074.
Eighteen of the 1934 UMF-3 and -5 (ATC 546) were built at $6,530, of which 4 went to Guatemala, and 3 to the Cuban Navy. They were the forerunner of the UPF-7.
The YMF-3 (ATC 542) of 1934 was powered by a 225hp Jacobs L-4. Powered by a 245hp Jacobs L-4, the YMF-5 appeared in 1935 for $6,795. Eighteen were built.
The design was revived around.1990 by Classic Aircraft Corp of Lansing MI as the YMF-5 Super.
Considerable numbers of ‘F’ series biplanes, both original and newly built, remained in service in mid-2009.

Waco AGC / DGC / EGC / MGC / ZGC / UC-72B / UC-72E / UC-72P / J2W / YGC
Seventeen 1937 AGC-8 (ATC 664) were built at a $9,895 price. Two were impressed by the USAAF as UC-72P (NC20905 and NC20909) in 1942, two were exported, and two were later modified as EGC-8 (X=NC2334 and NC19364).
The EGC-7 Custom Cabin of 1937 (ATC 639) sold for $10,390. Thirty-eight were built, of which 30 went to Brazil, and 3 to the USN/USCG as J2W. Seven were civil (NC1312, NC2209, NC2239, NC2241, NC17706, NC17724, and NC17749). Manufacturing rights were granted to the Brazilian government in 1939, but it is unknown if any were produced there.
Seven EGC-8 (ATC 665) were built from 1937; NC2279. NC2329, NC19354, NC19357, NS19365, NC19382, and NC19375, plus 2 conversions from AGC-8 (NC2334 and NC19364) selling for $12,680. Four were impressed by the USAAF as UC-72B.
One, NX2334, was tested with a 260hp Menasco D-6 for the MGC-8.
Most military operators operated either a single example, or a very small number. Military operators included Exército Brasileiro of Brazil (30 EGC-7), the Royal Netherlands Air Force possibly impressed an EGC-7, Nicaraguan Air Force (EGC-7), and the Royal Air Force impressed one ZVN-8 in 1942 as UC-72B and four ZGC-7 in 1942 as UC-72E.
The 1937 built DGC-7 Custom Cabin (ATC 639) sold for $10,390. Two examples were built: NC2239 and NC17706.
No one ever ordered the 1937 YGC-7 and the 1938 YGC-8 had new flaps.
Twenty-eight 1937 ZGC-7 (ATC 627) were built at $8,935, of which 4 were impressed by the USAAF as UC-72E.
Four 1937 ZGC-8 (ATC 664) were built at $10,495; NX=NC2272, NC19355, c/n 5053 to Argentina, NC19360, VT-AKD. The first one (prototype, c/n 5001) was later modified with an L-6 engine as an AGC-8.

Waco A series / BBA / IBA / ICA / KBA / KCA / PBA / PCA / PLA Sportsman / RBA / RCA / TCA / UBA / UCA / ULA Sportsman / TBA
The Waco A series is a range of light American-built twin side-by-side seater sporting biplanes introduced in 1932 as an affordable private-owner aircraft with cross-country range and baggage capacity and a more sporting image than the larger Waco F series. The A series offered a number of engine options which had varying sub-designations. The power range lay between the KBA with a 100 hp (75 kW) Kinner engine and the later UBA with a 210 hp (157 kW) Continental powerplant.
The PLA “Sportsman” of 1933 (ATC 502) introduced a longer wider fuselage and a higher useful load and had a 170 hp (127 kW) Jacobs LA-1 radial engine. With a side-by-side cockpit with sliding canopy, four were built; NC13067, NC13073, NC13401, and NC13410, priced at $4,285.
The last model in the series was the ULA, also of 1933, with a 210 hp (157 kW) engine.
Relatively few were produced and the type survives in small numbers in 2009.
The 1932 Waco BBA was powered by a 165hp Wright J-5 and featured an enclosed, side-by-side cockpit. Possibly there was only one conversion for motor installation tests since there is no record of actual production.
The 1932 Waco IBA (ATC 465) featured a two place side-by-side canopied cockpit. Priced at $4,059, three were built; NC12435, NC12446, and NC12453.
The 1932 Waco KBA (ATC 460) built was registered NX/NC12435 and sold for $3,585. Featuring a two place side-by-side canopied cockpit and became the Waco IBA with an engine upgrade.

The 1932 RBA (ATC 466) carried two side-by-side with a canopied cockpit. Priced at $4,195, four were built; NC12435, NC12442, NC12444, and NC13401. Higher speeds were reached with rerated 125hp Warner and cowling.
The 1932 three seat Waco RCA sold for $4,195.
The 1932 TBA (ATC 474) featured a side-by-side cockpit with an optional canopy. They were available for $4,490 but none was produced. The three place open cockpit TCA was available for $4,285 but there was no actual production. The three place open cockpit UCA was a planned project (for $4,895), but produced as the UBA.
At least six 1932 Waco UBA (ATC 479) were built, priced at $4,895, with side-by-side cockpit and optional canopy.

Waco JYM / JWM
Two mailplane derivatives from the O series (types JYM and JWM) were single seaters with a 14″ stretch in the fuselage.
The JWM was a straightwing derivative of which two were built, including NX8550.
The JYM (ATC 2-361) was a taperwing derivative of which four were built, NR42M, NR631N, NC731K, NC991, for Northwest Airways in 1929.

Waco 10 / GXE / 90 / ASO / 220-T / ATO / BSO / CSO / CTO / DSO / HSO / HTO / JTO / JYO / KSO / OSO / PSO / QSO / RSO / 240-A / O Series / Taperwing
Designed by Charles Meyers, the Waco 10 was a larger span development of the Waco 9, both single-engined three-seat single-bay biplanes constructed around steel-tube frames. The wing covering was fabric, and both upper and lower planes carried ailerons, which were strut linked. The two passengers sat side by side in a cockpit under the upper wing and ahead of the pilot, who had a separate cockpit. It had a split-axle fixed undercarriage and a tailwheel. The main undercarriage was fitted with hydraulic shock absorbers, unusual at the time on a light aircraft. The fin could be trimmed on the ground to offset engine torque, and the tailplane could be trimmed in flight. Initially it was powered by a Curtiss OX-5 water-cooled 90° V-8 engine producing 90 hp (67 kW).
Its first flight was in 1927. The improved WACO Model 10 replaced the Nine in 1927, featuring a larger wing area, bigger cockpit, an adjustable stabilizer, and the first shock absorber landing gear built into a small aircraft. The WACO 10’s performance was markedly enhanced and the aircraft was sold with several different engine options (OX-5, OXX-6, Hispano-Suiza and Wright J-5 Whirlwind).
Noted for quick and straightforward takeoffs, a speedy rate of climb and equally tolerable landing speeds, the WACO 10’s performance soon made it the most popular small aircraft in the United States. By 1927, more than 40 percent of small aircraft sold in the country were WACOs, including 350 WACO 10s at a sticker price of $2,460 (with the OX-5 engine). The WACO 10’s reputation extended to the air race circuit as well: an OX-5 engine-powered model won the 1927 New York to Spokane, Washington, transcontinental Air Derby (Class B) and a Wright J-5-powered WACO 10 won the National Air Tour the following year.
Advance Aircraft went on to manufacture the notable WACO Taperwing in 1928 and then, in 1929, the company officially renamed itself the WACO Aircraft Corporation to correspond with its line of aircraft.
A Taperwing was flown to victory in the 1928 National Air Derby by Johnny Livingston a well known aviator, WACO dealer, airline operator and daring air-racer of the day.
In 1928, after the Waco 10 had entered production, Waco changed its designation system so that the basic model 10, powered by a 90 hp (67 kW) Curtiss OX-5 engine became the GXE. The OX-5 was also used in the Waco 9, and this led to the confusing popular description of both aircraft as Waco 90, after the power.
Other engines were fitted experimentally, without unique designations, including Rausie, Siemans, and the 115 hp (86 kW) Milwaukee Tank engine (ATC 2-363) in 1931. This was an air-cooled version of the Curtiss OX-5, and was intended as an aircraft engine.
Later aircraft used a three-letter designation, the first denoting the engine, the second, S or T meaning Straight or Tapered wing and the final O indicating it belongs to the Waco O series for open cockpit. An -A suffix indicated an armed variant intended for export.
The Waco 10 turned out to have excellent handling, and there was a ready supply of war-surplus Curtiss engines. It was widely used for the popularisation of aeronautics through barnstorming and joyrides, and was also much used as a trainer and by small operators for charter flights.
The 1931 240-A was a single place armed export version of the CSO with a 240hp Continental W-670. Possibly only one was built.
It was numerically the most important type to be built by Waco (ATC 13), with at least 1,623 built over a period of 7 years from 1927 to 1933 and was fitted with a very large variety of engines of radial and V configuration. The unit cost was $2,145 minus engine & prop. The total price was $2,460, $2,385 in 1928, and $3,145 in 1929.
The Advance ASO or 10-W, and 220-T of 1927 (ATC 41) was also popularly known as “J-5 Straightwing,” “Waco Sport,” or “Whirlwind Waco.” ATC 2-101 covered weight changes and ATC 2-102) for EDO floats.
The ATO aka 10-T Taperwing of 1928 (ATC 123) was designed by Charlie Meyers and first flew on 30 April 1929. The price was $8,325 and 54 were built. Sometimes popularly referred to as “Waco 220” for its horsepower.
The BSO (or BS-165) of 1929 operated under ATC 168 (and 2-262 for EDO twin-float modification) and about 45 were built, at $6,370.
Twenty-nine CSO / CS-225 was built in 1929 for $7,335 under ATC 240. Thirty military exports as CSO-A and 240-A were built in 1932.
The 1929 CTO (or 225-TW) (ATC 257) was a taperwing CSO. Thirteen were built plus 22 military versions as CTO-A in 1932. ATC 2-378 was for two single place models with 240hp Wright R-760 engines and raked top wing with I-struts; NC21M and NC666N.
The Waco DSO / 10-H (ATC 42) of 1928 sold for $3,935 with the 150 hp Hisso A ($4,085 with Hisso E) and 62 were built. 2-ATC 245 was for the EDO float conversion.
The 1930 HSO (ATC 333) was designed by A Francis Arcier (principal Waco designer from 1930-47). The one built, NX/NC4N, was priced at $7,500 and later modified as taperwing HTO NR4N.
The 1929 three-place JTO was powered by a 300hp Wright J-6. The one built, N13918, was refitted with a 365hp Wright R-975 in 1932 but only test-flown.
The 1933 JYO were two USN version of the JTO for evaluation.
One Waco KSO was built, NX795E, in 1929. Possibly a modified GXE with a 100hp Kinner K-5.
One Waco PSO (ATC 339) was built, NC699N, in 1930, priced at $5,175.
One WACO QSO (ATC 337) was built in 1930, NC837V, priced at $5,575.
One Waco RSO was built, in 1929, NC9531.

1 conversion of Waco 10
Waco AQC / DQC / EQC / UQC / VQC / ZQC / J2W-1 / UC-72G / UC-72H / UC-72Q
Manufactured from 1936, sixty-eight AQC-6 (ATC 598) were built.
The ZQC-6 model (285 hp Jacobs L-5MB engine) could be converted to an AQC-6 (330 hp Jacobs L-6MB).
At least two AQC-6 Freighter aircraft and eight ZQC-6 Freighter aircraft were ordered through Fleet Aircraft and built for use in Canada with additional freight doors on both sides of the fuselage and equipped for floats. Additional aircraft may have been modified. CF-BDW appears as EGC-7 in some regs.
Twenty EQC-6 were built in 1936 (ATC 597) for $9,650. The USCG used three EQC-6 bought from Waco as J2W-1 (V157, V157, and V159). One ZQC-6 was impressed by the USAAF as UC-72Q and five as UC-72H in 1942. Additional aircraft impressed by the US Navy were undesignated.
US Army Air Forces designation for impressed Custom Cabin series Wacos.
UC-72Q – one impressed ZQC-6
UC-72G – one impressed AQC-6 (NC20906)
UC-72H – five impressed ZQC-6
The Swedish Air Force designation for ZQC-6 was Tp-8a and Tp-8 was a generic designation for all Wacos.
The Royal Australian Air Force impressed a YQC-6 serialled A-54. It was re-engined with a 200 hp (149 kW) De Havilland Gypsy 6 inline engine in 1946 (VH-UVW).
The Argentine Navy operated EQC-6 and UOC. The Royal Canadian Air Force impressed AQC-6. The Canadian Department of National Defence purchased two ZQC-6. The Finnish Air Force impressed ZQC-6.
The DQC-6 of 1936 (ATC 597) seated 4-5 and sold for $8,975. Eleven were built: NC2277, NC15706, NC15714, NC15722, NC16214, NC16218, NC16515, NC16520, NC16525, NC16591, and NC16595.
Three USCG version of the EQC-6, on twin floats for operation from a cutter, and EGC-7 on wheels, were built in 1937 as J2W-1; V157, V158, and V159.
One 1937 VQC-6 (ATC 631) was built (NC16243), reportedly first registered as UQC-6, but unconfirmed by factory records.
