There are several ultralight models in Brazil from different manufacturers. Some are of completly domestic design and some are just built from imported kits (like from Rans or Zenair). The planes are delivered always completelly built.
Here I list the manufacturers with phone and addresses, the options actually offered by them and technical description of some planes:

The most common engine for utlralights here is the Bombardier Rotax too, with its different flavors. The 503, 582, 618 and also the four-stroke option of the 912.
Another option is the Volkswagen 1800 used in Astro and Fênix, this one has the advantage of reliability and easy maintenance (you can find specialists in every corner of the country), but on the other hand the disadvantage of it is its weight.
Here some specification data for the Rotax engines.
