The Comp Air 4 (also known as the Comp Monster) is a light civil utility aircraft manufactured in kit form with a number of different options. Builders are able to choose between an airframe designed for engines in the 140-180 hp (104-134 kW) range and a heavier one for 250 hp (187 kW) units. The latter airframe can be fitted with up to six seats while the standard airframe seats four. The Comp Air 4 may be built with tailwheel tricycle float or amphibious float undercarriage.
