The S.4 was a short-lived project for an all metal sesquiplane
single engined fighter armed with two M.G's.(type unknown)
No drawings. No further info for S.5 to S.9
Designations not mentioned.

René Bulté worked for the Belgian state's technical department (Service Technique de l'Aéronautique) until 1926, then for Zacco, where he participated in the construction of the Acaz C.2 and its subsequent modification as a long range aircraft.

Around 1927, he designed two projects on his own:
- a single engine 450hp transport monoplane for 10 passengers
- a two engine transport amphibian for four passengers
Those were not produced.

In 1928, he left Zacco and created his own society "Avions Bulté". At some time in the 1930s, the company was taken over by Jef Guldentops who continued the production of the RB.30 as "Bulté-Guldentops".

In 1932, René Bulté was hired by Minerva engines, then in 1934 by Lacab, where he participated in the construction of the GR.8 Doryphore. After 1936, he left the aircrafy industry for other activities.

The RB.1 was the first Bulté aircraft actually built.

The first two aircraft were built by the SEGA workshops at Gosselies in 1928:
- first prototype O-BAJL, christened "Hélène", later OO-AJL
- second modified aircraft O-BAJR, later OO-AJR
Three others were built by Avions Bulté in 1930-31: OO-AKR, -ALD, -ALJ. Of those, OO-ALD was briefly sent to Britain for Seelandair, a prospective sales company which soon went bankrupt.

The aircraft was normally equipped with an Anzani 6-cylinder radial engine (visible in photographs of O-BAJL, -BAJR, OO-AKR, -ALD), but drawings also exist with a Renard 5-cylinder engine.

The next aircraft was the RB.29, whose name might correspond to the year 1929.

Three were built by SEGA at Gosselies in 1928-1929, registered OO-AKC, -AKD, -AKE.

Three different engines were tried on these aircraft:
- Hispano 100 hp 6-cylinder inline water-cooled engine (on -AKC)
- Renard 100 hp 5-cylinder radial engine (on -AKD)
- ADC Cirrus III 85 hp 4-cylinder inline air-cooled engine (on -AKE)

One of them (perhaps -AKC or -AKD) was damaged in speed record attempts in February 1930.
Later in the same year, two RB.29 (probably -AKC and -AKD) were completely destroyed in a workshop fire, after which any attempt at building further examples was abandoned.

At some time, the third aircraft OO-AKE was hired by the government for an exhibition tour and had the word "Travail" prominently painted on the sides. On other pictures, the same aircraft has the name "Coccinelle" painted on the side instead.

(Same sources.)

The final model was the Bulté RB.30 Sport. (The designation perhaps corresponds to the year 1930.)

This biplane has nothing to see with Guldentops designs like the St-Hubert and St-Michel. But in later years it was sold as "Bulté-Guldentops" after Guldentops took over the Bulté company.

The study of the aircraft was started in 1930, and plans were entered in a state competition for light aircraft projects, with various engine options: Salmson 40 hp, Walter 65 hp, Gipsy I 85 hp, and others up to 110 hp. (It seems that the actual aircraft had Cirrus Hermes 100/105 hp engines.) In the competition, the design lost to the Guldentops St-Michel.

Nine aircraft were built by Bulté in 1931, and three others were almost completed by mid-1932.
These include the prototype OO-ALU, completed in March 1931, and several other aircraft registerd in Belgium: OO-ALW, -ALX, -ALY, -ALZ, -AMA, -ANA.
Of these, OO-ALX was equipped with an enclosed cabin and supplemental fuel tanks for a long distance flight to Africa in early 1932.
It is also reported that one aircraft was exported to France in 1931.

There is very little information available about the later examples sold as Bulté-Guldentops. One aircraft was registered OO-ARZ by Guldentops, in 1937, with a Cirrus Hermes 120 hp. Another aircraft was registered in France as F-AQLU in 1938, with serial number 30.

Finally, a report of the Bulté company dated 1932 (reproduced in BAMM no.47) mentions two further projects:
- the Bulté Trainer, a military training aircraft
- the Bulté Racer, a fast touring monoplane
It seems that the original document contained drawings of these aircraft, but these were unfortunately not reproduced in BAMM.

There is no mention of a numerical designation for those projects. (This particular document uses numerical designations for the RB.1 and RB.29 only, but not for the RB.30, which is only called Bulté Sport.)

Here is the Mulot AM.20 Sport.

The first example was built in 1925, registered O-BAFS and later OO-AFS. Its engine was a six-cylinder radial, maybe an Anzani (?)
The photographs show various modifications, for example in the shape of the fin and rudder, the wheels, or the propeller.
The same aircraft was photographed in 1937 with a different engine, perhaps a Pobjoy.

The second AM.20 was registered OO-LIL. It was described in Les Ailes 19 August 1937. It had a Train 60 hp six-cylinder inline engine. (For the engine mounted on OO-LIL, see the discussion in a later post.)
The article in Les Ailes says that the AM.20 could receive a Train 60 hp or a Cirrus Minor 85-90 hp engine.
Similar engines were mentioned for the AM.20 in an undated brochure by the "Ateliers de Constructions Aéronautiques Mulot & Ertag".

The same brochure also mentions a side-by-side cabin two-seater named Baugniet-Mulot-Ertag, offered by Mulot & Ertag "under license".
It was different from the AM.20, but its configuration is not known. It was offered with a DH Gipsy or Renault 120 hp engine.
It might have been designed by Lucien Baugniet, who was the owner of OO-AFS at some time in the 1930's.

About the fate of the two AM.20, registration lists by André Dillien say that they were sold to France, OO-AFS becoming F-BCZS in 1946 and OO-LIL being registered in the F-Axxx series in 1937. However the site Belgian Wings says otherwise: "OO-LIL was destroyed before 1940 while OO-AFS did not survive the war".

Hi Hesham,
You are right, there was a Mulot A.M.220.

The designer André Mulot was a Frenchman, employed by SABCA in Belgium.
After WW2, the first Mulot OO-AFS was modified in France as a two-seater with Cirrus 90 hp engine. It thus became the A.M.220, registered F-WCZS then F-PCZS. It was described in Les Ailes 11 October 1947 as the "Mulot-Sport A.M.220".

There was an article about André Mulot and his aircraft in Trait d'Union 235, but I don't have it. It is surely the best available source about these aircraft.
Incidentally, according to its description in the Trait d'Union index, it seems that the first aircraft O-BAFS was originally called "motoaviette Labor", not A.M.20.

The Mulot registered O-BAFS first appeared as a parasol monoplane with 18 hp Vaslin engine, named the Mulot Labor. It was entered a the 1925 glider and light plane competition at Vauville.

There is a picture of the aircraft in its original configuration in the website claudel.dopp.free.fr:
http://claudel.dopp.free.fr/Les_planeurs/Histoire/Vauville-1925/Vauville-1925_machines.htm
and another in Flight 13 August 1925:
http://www.flightglobal.com/pdfarchive/view/1925/1925 - 0521.html

Those photographs show considerable differences from the later configurations as OO-AFS.

Cambier made two ultralight planes:
- the Cambier I, a monoplane with Sergeant 16 hp engine, registered O-BAFI in 1924
- the Cambier-Guldentops CG-2 "Camgul", a biplane with Anzani 60 hp engine, registered O-BAFU in 1925, later OO-AFU,
At least the second one was made with Jef Guldentops, who was chief of the Sabca workshops.

In 1925, the CG-2 was entered in the 5th light plane competition at Bruxelles, in the light plane competition at Vauville, and in the Coppa d'Italia in Rome. In 1926, it was entered in the "Concours d'Avions Économiques" at Orly. In 1927, it participated in the 6th light plane competition at Bruxelles. In 1928, it was offered for sale without engine by Sabca in Les Ailes.

In contemporary periodicals, one can find both spellings "Cambgul" and "Camgul".

Some additions about the Mulot AM.20.

The Mulot AM.20 was reportedly shown at the 1937 Bruxelles salon with Gipsy I engine:
http://www.flightglobal.com/pdfarchive/view/1937/1937 - 1478.html

The article in Les Ailes 19 August 1937 and the brochure at Collection Philippe Veys only mention the Train 60 hp six-cylinder or the Cirrus Minor 85-90 hp four-cylinder engine. The Train was an inverted engine, and there is no photographic proof that it was mounted on the Mulot.

In late 1937, André Mulot was looking for a financial backing for his aircraft, placing an ad in les Ailes.

In 1939, one of the AM.20 was in France, under testing for the CNRA registration (permit to fly).

This plane was designed by Carlos Regnier (or Régnier, but I'm not sure his name had an accent), from Gand, and built in the Mulot workshops. It was registered OO-REG on 8 Aug. 1936.

It is usually called Régnier R.1 in today's sources. However it was exhibited in the Bruxelles salon in 1937 with the name "Régnier-12" on the tail, and it was described under that name in Les Ailes 10 Jun. 1937. (In Les Ailes 3 Jun. 1937 it is called "Régnier 1-2" instead.)

It was a side-by-side two-seater, designed for a Train 40-50 hp engine. Les Ailes says that it made its first flights as a single-seater with a provisional 27 hp engine, and says that it could also be equipped with a Walter Mikron 50 hp.

Regnier also studied a light two-engined pusher monoplane with tricycle gear. The two 50, 70 or 90 hp engines would be mounted on the trailing edge. The aircraft would have two, three or four seats, depending on the power output ; these projects were respectively called Regnier 22, 23, 24. The general configuration was similar to the Oplinter Long Courrier or Air Taxi:
http://www.secretprojects.co.uk/forum/index.php/topic,15575.msg305139.html#msg305139

Carlos Regnier joined the RAF during WW2. He was not related to the Régnier engines made in France.

At the end of the 1920s, Jef Guldentops, backed by José Orta, designed a light parasol monoplane, the Saint-Hubert G.1 (or G.I). The aircraft was called Orta Saint-Hubert G.1 in the press and in registration documents.
José Orta owned an aviation school in the town of Saint-Hubert, with Bloom as chief pilot. He was the brother of Tony Orta, a famous pilot who held a high position at Sabena.

The Saint-Hubert G.1 was described in Les Ailes 7/11/1929:
http://gallica.bnf.fr/ark:/12148/bpt6k6554668p/f3.image
According to the article, there were two main versions, differing by the engine:
- a Walter 65 hp, perhaps the NZ-60 5-cylinder radial (actually 60 hp), carrying two people;
- a Walter 85 hp, certainly the NZ-85 7-cylinder radial, carrying three people.

Jean-Pierre Decock says that the first two aircraft were built by Guldentops in Bruxelles, and that the first flight took place in 1927. The prototype was registered O-BABI in September 1928. Early photographs show a 5-cylinder engine. Its registration became OO-ABI in 1929, and it participated in the 1929 European Challenge together with the second aircraft OO-AKH. At the time, both had a 7-cylinder Walter NZ 85 hp. OO-AKH, piloted by Vuylsteke with Fabry, could not start the race in time. OO-ABI ended in the 31st and last position, piloted by Maus with Lambilly. Those were wounded in a crash on 21 June 1930 on a Saint-Hubert, certainly OO-ABI, that was struck off the register in 1931. (L'Aéronautique 08/1930)

In Autumn 1929, Guldentops left his position at Sabca to start series production of the Saint-Hubert G.1 at the Saint-Hubert aviation school. At the time, a first batch of six aircraft was started (Les Ailes 31/10/1929). These were OO-AKL, -AKO, -AKX, -AKY, -ALK, -ALL, registered between Dec. 1929 and Aug. 1930.

Among these, OO-AKO had a DH Gipsy 85 hp inline engine, and was named Orta Saint-Hubert G.2 in the registration documents. It crashed on 14 May 1935 at Schulen, but was perhaps rebuilt, registration lists saying that it was destroyed on 10 May 1940 at Gossoncourt.
OO-AKX was entered in the 1930 European Challenge with a Walter 110 hp 7-cylinder engine.
OO-ALK was transferred to Luxembourg as LX-ALK in 1935, but was in Belgium again in late 1936.
OO-ALL was used by Albert Maréchal and Géo Clavier to travel from Bruxelles to Tehran. It had a Walter 85 hp 5-cylinder, perhaps the Walter Vega. It crashed in 1933 but reappeared in 1935, and became LX-ALL in Luxembourg in 1938.

In Winter 1931, the two partners broke and Guldentops set up his own workshops in Bruxelles-Evere, where he would build the Saint-Michel aircraft. (Les Ailes 19/03/1931)

Orta continued the production of the Saint-Hubert G.1 on his own for a short time. The aircraft registered after Guldentops left the factory were OO-BSC (for the Belgian Shell Company), OO-AMB, -AMC, -AMS, -AMT, -AMU, -AMV. (Registration OO-AMD is also mentioned in the list by André Dillien, with no date. It was perhaps not taken.) The last one was registered in September 1932.

New engine types were installed on this batch. For example OO-AMT had a Renard 120 hp and a picture of OO-AMS seems to show the same engine. Les Ailes mentions a new model of Saint-Hubert displayed in September 1931 with a Cirrus Hermes 115 hp engine, certainly one of the same batch. (Les Ailes 10/09/1931 and 29/10/1931)

After he set up his own factory, Guldentops developped the Saint-Michel S.G.2 (or S.G.II), an evolution of the Saint-Hubert G.1. Jean-Pierre Decock says that computations were checked by Robert Servais (designer of the Lacab T.7), hence the S.G. designation. The Saint-Michel is very similar to the Saint-Hubert, with a different tail.

(Because the Saint-Michel was made after Guldentops broke with Orta, the name "Orta Saint-Michel" that is sometimes found in recent documents is wrong.)

The Saint-Michel first appeared with a Renard 100 hp five-cylinder radial. (Les Ailes 29/10/1931)

A total of ten aircraft appear in Belgian registration lists. In the registration documents, nine of them were called Guldentops S.G.2 Saint-Michel, registered OO-GUA to -GUI from 1931 to 1936, with c/n 1 to 9.
Among these, OO-GUA, -GUB, -GUF and -GUG had a 5-cylinder radial, certainly a Renard 100 hp or 120 hp, and OO-GUE, registered in 1933, had a DH Gipsy inline engine.

The tenth aircraft also had registration OO-GUI, allocated in 1934. It had a DH Gipsy 105 hp inline engine, and it was flown by Arnold de Looz-Corswarem in December 1934 and January 1935 from Bruxelles to Léopoldville (today Kinshasa), and crashed near Alicante during the return trip.
In registration lists, this aircraft appears as the Guldentops S.G.1 St-Michel, with c/n 1. Despite this, it was called SG-2 in the press. (Les Ailes 17/01/1935)

After the crash, the registration OO-GUI became vacant, and was taken up again by S.G.2 c/n 9 in 1936. This aircraft was later sold to a French owner and became F-AOYA.

José Orta and the Saint-Hubert aviation school made a few more aircraft after the end of the series of Saint-Hubert G.1.

The Saint-Hubert 135 B.O. was designed by Pierre Baudoux and José Orta, hence the B.O. designation. It was a low-wing monoplane with two seats in tandem and a Cirrus Hermes IV 135 hp inverted inline engine.
The first aircraft was pictured in Flight 14/12/1933, apparently unpainted. It was registered OO-ANN in January 1934.

Another aircraft was registered OO-ASZ in 1937. It is also listed as an Orta Saint-Hubert 135 BO in registration lists, but Jean-Pierre Decock says that it was actually a Saint-Hubert 80 B.O. with 80 hp engine.

The Saint-Hubert S.B.O. or 6 B.O. was a very light aircraft designed by Pierre Baudoux and José Orta. Jean-Pierre Decock says that the S.B.O. designation means "Saint-Hubert Baudoux Orta", but an original brochure shows the name 6 B.O. instead.

It was a single-seat parasol monoplane, with a Saroléa 25 hp pusher engine. It was described as a motor glider in Les Ailes 18/04/1935.
Two aircraft were made, registered OO-ANX and OO-ANZ.

Maurice Peetermans made the S.E.A. aircraft from 1936 to 1939. The name "S.E.A." means "Société d'Études Aéronautiques" (Society for Aeronautical Studies), but it seems that this was a commercial name only, and the company was not legally constituted.

The S.E.A. 1 was a low-wing monoplane with two Armstrong-Siddeley Genet Major 165 hp radial engines, and retractable gear. It was designed by Pierre de Groef, assisted by MM. Eleaume and Florizone. It was intended for civilian or military use, and could carry six passengers or two machine-guns and small bombs for ground attack.
The only aircraft built was registered OO-PET (surely for Peetermans), and first flew in 1936.
It was described in Les Ailes 3 Sep. 1936, and exhibited in the Bruxelles Salon in May 1937. (Les Ailes 3 Jun. 1937, Flight 3 Jun. 1937)
In Summer 1937, it was tested by the French CEMA flight test centre. (Les Ailes 5 Aug. 1937)

However the Belgian air force did not proceed with the aircraft and abandoned the idea of ordering two engine light aircraft, planning to buy single-engine four-seat liaison and training aircraft instead.

The S.E.A. 1 was therefore transformed into the single-engine S.E.A. 2 in 1938, registered OO-PAT. It now had a single Armstrong Siddeley Cheetah IX engine (340 hp). The prototype had a spatted fixed gear for lack of time, but the series version was planned with a retractable gear.
The first flights were announced in Les Ailes 18 Aug. 1938. The aircraft unfortunately crashed in early September 1938.

Peetermans then bought the license of the Oplinter W.4 to Jean de Wouters d'Oplinter, and started three examples of the aircraft, renamed S.E.A. 3. According to Les Ailes 20 Jul. 1939, two aircraft were exhibited at the 1939 Bruxelles Salon, but these perhaps included the original W.4 prototype.

Peetermans had plans for a larger and more powerful version of the W.4 for military training, called S.E.A. 4. This might correspond to a drawing by Oplinter showing a W.4 with 6-cylinder engine and retractable gear, reproduced in BAMM no.95.
