Outstanding.

This is subject should be an excellent first scale project. It's an R/C trainer @ full size! Almost slab sided, even. Hardest part is building that tapered wing, built-up or foam. As much or as little detail as desired. Wide range of color schemes. Good ground handling. Good drawings, apparently.

The Bo 209 is the successor model of the Bölkow 208 Junior, a license construction of the MFI-9 Junior from Malmö-Flygindustri (MFI) from Sweden. In 1965 the decision was made to develop a successor to the Junior. Hermann Mylius presented his designs together with a development cost estimate of 1.2 million Marks to the MBB board, which, however, rejected them. The "monsoons" were created from 1966, when Hermann Mylius, Walter Heyen and Johannes Krauss founded the "Development Group Light Aircraft" in Brunnthal on 6 September 1966. The project was named MHK 101. The project was supported by Ludwig Bölkow and further engineers from the company Bölkow from Ottobrunn joined the group. After almost two years of development, the prototype MHK 101 V0 started its first flight on December 22, 1967 with a 115 hp Lycoming O-235-C2A in Laupheim. At the aircraft show in Hanover in 1968 the machine was shown on the booth of Bölkow and finally named as the successor of Bölkow 208. After numerous improvements (for example, the Lycoming O-320-B with 150 hp) and an in-depth market analysis, the aircraft went into series production at the Laupheim plant under the official name Bo 209 Monsun 1969 after being first demonstrated in Egelsbach in May 1969. The model approval was given to Bo 209 on 11 May 1970.

The monsoons had unique features of their class: space-saving storage and transport through the foldable surfaces, retractable nose wheel, low consumption and purchase price, high travel comfort and low noise development.

The 209 was also offered in four different versions. The 209 S was a simplified training model with rigid nose wheel, without flaps and with a 115 hp engine. The top model was fully aerobatic and equipped with electric flaps, retractable nose wheel and a Lycoming engine O-320-D1A with 160 hp and variable pitch propeller.

Depending on the engine and equipment, the sales price ex factory was 38,659 to 59,950 DM

With this wide range of equipment features, Bölkow was able to convince at the 1970 aviation show in Hanover: 57 pre-orders of the new type were signed. A commercial success of the project seemed to be secured. In 1968, however, the merger of Bölkow GmbH into the MBB Group had led to the economic basic decision to cease civil aircraft construction. Although 102 monsoons were produced between 1969 and 1971 and 275 orders were still available, MBB decided to stop production in February 1972. Attempts by Reinhold Ficht to continue the production could not be realized.

The Bo 209, however, was still used as a model for the Mylius My 102 Tornado (a single-seater art aircraft with monsoon wings and AIO-360-B1B with 200 hp), which had its first flight on July 7, 1973, and later on a second Copy was built.
