Rotax engines (see) are built in Gunskirchen, Austria by Bombardier Recreational Products, a division of Bombardier Inc. Montreal, Canada.

-Rotax actually was founded in Dresden, Germany, in 1920 and in 1943 it went to Austria and specifically to Gunskirchen in 1947.

-During WWII they were very successful building small engines for multiple uses.

-By 1962 they built engines for snowmobiles, which were used by ULMs and VLAs.

-It was acquired by Bombardier, and from 1982 they began building a line of 2-stroke engines that acquired great fame until today. They are also used in personal water craft (PWC).

-These were one-, two-, and three-cylinder, inline upright engines.

-They also made horizontally-opposed cylinder engines such as the 906, 912 and 914 models. Currently they are developing major V-engines that deliver 220 and 300 CV known as Rotax 936. For more engine details, see Rotax.

From Appendix 6: Bombardier Recreational Products through its Rotax subsidiary (see) provides engines for ultralight and VLA.

-But currently the (JAR-Y / FAR-33) are approved. These are two engines that can be fully used as a retrofit in many older models of general aviation.

-Both are six-cylinder V-engines with two rows of three cylinders at 120°.

-They are the V-220 and V-300T, giving 220 y 300 HP respectively.

-They are basically the same engine, but the V-300T has a turbocharger. Rotating at 6,000 rpm, like automotive engines, and with gear.
