Hi Hesham and all!

Some additions and corrections:

Ae-03 was high-altitude photo recon aircraft (probably the very first!) and it was single-seat, accordind to Vaclav Nĕmeček. It was quite small aircraft, of “fighter size” – only 8.20 m wing span. See .

A-16 was unbuilt project of single-engined biplane night bomber, designed in 1926.

A-22 you mentioned was already second application of this index. The first one was unbuilt project of heavy bomber biplane with four 300-hp Hispano-Suiza 8Fb engines, designed in 1924 and resembling Handley-Page V.1500.

A-27 bomber project was also the second one under this number. The first one was designed a bit earlier – in 1925; it also appeared to be A-24 derivative but not a bomber – it would be an airliner carrying 12 passengers, with two Lorraine-Dietrich 12Cc engines.

A-33 was 14-seat airliner project, designed in 1928. It was trimotor biplane with radial engines: one 480-hp Walter Jupiter (license Bristol) as the central one, and two 380-hp Walter Pollux.

A-36 (1926) was biplane bomber project with three Jupiter engines. The third engine was placed on the upper wing center section as pusher.

A-40 was a project of racing biplane resembling Curtiss racers in appearance. It was planned for 1926 President Cup. The engine was Skoda L boosted up from 450 to 620 hp, and the maximum speed was calculated as much as 410 km/h.

A-42 had unbuilt twin-engine version – the A-42c with 500-hp Walter Merkur IV radials (license-built Gnome-Rhone Mercure which were themselves license-built Bristol Mercury).

A-44 was a project of heavy bomber monoplane with two Praga Asso engines (Isotta-Fraschini license), designed in 1931, a bit resembling Dornier Do 23 or larger version of mentioned A-42c, but with unusual triple-fin biplane empennage.

A-48 (1932) was 8-seat airliner project, a high-wing monoplane with three Walter Pollux engines.

A-49 was two-seat parasol-wing ultralight aircraft project, designed for the competition which winner was Letov S-39.

A-55 was another ultralight project, a high-wing monoplane powered by 50/60-hp 3-cylinder Walter Polaris radial.

A-60 projected in 1933 was passenger aircraft with three Walter Castor radials: the first Aero’s low-wing cantilever monoplane with retractable landing gear, it could carry 6 passengers with 280 km/h speed.

A-202 (1934) was twin-engine cantilever low-wing monoplane airliner project with retractable landing gear, probably 14-seat (rival to Avia 57).

A-210 project looked like A-202 evolution but with four 550-hp Walter Sagitta inverted V12 engines, designed to carry 14 to 20 passengers.

A-212 (1937) project was kind of Ae-45 precursor but with more “conventional” appearance. The engines were Walter Minor (the particular version is not specified in Nĕmeček’s book), estimated maximum speed was 265 km/h.

Your text about A-204, 206, 300 and 304 needs some corrections. A-304 wasn’t refined A-300: actually it was earlier design and more closely related to basic civil A-204 – the only changes were more powerful engines (435-hp Super Castors instead of 360-hp Polluxes), a turret with single machine gun for defense and some additional equipment. The A-206 was projected as more specialized bomber, with much more powerful Bristol Mercury IX engines (650/830 hp) and redesigned fuselage; the project was presented in May 1936 but in July the National Defense Ministry required some changes (including twin-fin empennage). So, the project was changed ant then renamed – since January 1937 it became known as A-300.

Also, A-430 wasn’t built as a prototype under this name – it was initial designation of what became A-100.

Some postwar designs:
Ae-145 produced in 1959-61 was the second one; the first Ae-145 was designed in 1948-49 as larger 5-seat Ae-45 derivative with 160-hp Walter Minor 6-III engines and tricycle landing gear. Ae-245 was similar, also 5-seat but with a tailwheel. Finally, Ae-345 was combination of Minor 6-III engines and regular Ae-45 airframe. Any of these versions wasn’t built.

Ae-148 (1949) was airliner project for two pilots and 12 passengers, powered by two 700-hp air-cooled inverted Walter V-12 (M-446) engines. (Logically, it must have a precursor designated Ae-48, but such one isn't mention in Nĕmeček’s book).

L-229 was projected as single-seat light attack version of the L-29. It was armed with two machine guns (the former rear cockpit was used for the ammunition) and had underwing pylons for bombs and rockets. Kind of “L-159” from early 1960s, but unbuilt.

L-260 and L-360 both designed about 1960 were L-60 derivatives: the first with 240-hp Praga M-208D engine, the latter with 260-hp Ivchenko AI-14R radial. Both weren’t built, but much later (since middle ‘70s) all remaining L-60 were converted for AI-14R engines – this version was designated L-60S.

Another L-260 projected in 1970 was high-wing 10-seat multi-purpose aircraft with single M-601 turboprop, resembling popular Pilatus Turbo Porter. Kind of a precursor for the later high-wing L-270.

L-429 isn’t version of L-29A: both designations belong to the same aircraft – single-seat aerobatic version of regular L-29. In similar way, the recon L-329 was also designated L-29R.

According the gliders VT-16, 116, 100, VSB-62 and 66 – they have no connection to Aero at all. They were designed by independent design teams of Medlánky (VT) and Brno (VSB), and produced by Orličan company (successor of Beneš-Mráz).

The LC-II (XE-II / XE-II-A) also included these variants (though they are all possibly the same airframe modified over again):

- XE-II-B - Cyclic control lever relocated above the pilot's head, first flew May 9, 1950.
- XE-II-C - Received a new type of rotor head and smaller tail rotor. Registration OK-FYA, became property of the Ministry of Transport in 1951.
- XE-II-D - (?) variant presented at Točná August 26, 1951.
- XE-II-E - Stabilizer added, fuselage fully enclosed.
- XE-II-F - Received stronger rotor blades. Crashed at the Chrudim airport in May 16, 1952. Pilot killed.

Was the Orličan firm directly related to Aero Vodochody? I thought that Orličan had taken over the former Beneš-Mráz plant at Choceň.

A.211 was a two seat recce aircraft or Project ?,maybe related to A.11 ?.

The Aero A-211 was indeed an A-11 development (the 1928 prototype was converted from A-11.105) but it was a 2-seat trainer not a reconnaissance aircraft. The A-211 was powered by a 240 hp Walter Castor 7-cylinder radial. Built between 1931 and 1933, most sources list 18 airframes.
