The ACS-100 Sora is a proposed Brazilian two-seat Light Sport Aircraft, designed by Advanced Composites Solutions.
The Sora (originally designated the ACS-100 Triathlon
) was developed from the CB-10 Triathlon
project designed by the Brazilian aircraft designer Cláudio Barros of the Federal University of Minas Gerais. The Sora is a two-seat side-by-side all-composite
low-wing cantilever monoplane
with a conventional tail unit
. It has a fixed tricycle landing gear
with retractable gear as an option. It is designed to be fully aerobatic
(+6g to -4g). The first flight was planned for May 2008 with delivery of the first aircraft planned for the first half of 2008.
