[1][2] The Ikarus C42 is a single-engined high-wing monoplane with side-by-side seats for two in a 1.22 m (48 in) wide cabin.

The cabin and fuselage shell is a composite material which, being non-structural, can be removed for inspection and repair.

The wing tips are of composite construction which reduces drag and improves low speed handling.

Electrical pitch trim is controlled by two buttons on the top of the stick, operated by the thumb.

The relatively short lever does make the operation of lowering flaps quite physical when combined with holding the centre control stick at the same time.
