Kaos

About

The Kaos is one of the most-built RC pattern aerobatic airframes in the history of the hobby — designed by Joe Bridi for AMA Pattern competition and produced by Bridi Aircraft Designs from the 1970s onward. Like every well-loved pattern airframe, the Kaos earns its place in the hobby by being three things at once: precise enough to fly the AMA Pattern competition sequences, forgiving enough that an intermediate pilot can fly it confidently after stepping up from a basic trainer, and simple enough to build over a few weekends from balsa, ply, and Monokote film.

The Kaos design language is the classic 1970s American pattern aerobat: low-wing taildragger configuration, symmetrical airfoil for equally clean inverted and upright flight, and the kind of long-coupled fuselage that gave the airframe stability in the demanding precision-aerobatic sequences of the AMA Pattern era. .60-class glow engines were typical, with both two-stroke and four-stroke installations common. Generations of competition pilots earned their AMA Pattern wings on Kaos airframes, and the type continues to be a popular sport-aerobatic mount today even as the dedicated 3D foamies and giant-scale gas competition mounts have evolved alongside it.

The bigger picture is the classic-RC pattern category itself. The Kaos and its kit-built siblings — the Goldberg Falcon, the Sig Kavalier, the Top Flite Tower Trainer 60 — were the airframes that defined American sport-aerobatic flying for two decades, and the silhouettes you see in many modern foam and balsa sport-aerobatic ARFs trace their lineage directly to this generation of competition designs.

In the simulator

A classic sport-aerobatic mount with the deliberate handling personality of a 1970s pattern airframe. The Kaos in our sim flies the way a real Kaos does — predictable, willing in aerobatic figures, and generous in stall behavior. Use it for traditional pattern aerobatic flying: loops, rolls, half-Cubans, hammerheads, and the sequences that AMA Pattern competition was built around. Pairs well with grass strips and any field with room for a clean aerobatic box. A natural step beyond the basic trainer.
