ISAAC’s FURY II

Isaacs Fury II: The Gentleman’s DIY Fighter

The Isaacs Fury II is a magnificent 7/10th scale replica of the legendary 1930s Hawker Fury fighter. Designed by the British engineer John Isaacs, it was created to fulfill every pilot’s dream: to fly a “Golden Age” biplane fighter without the million-dollar price tag. It is not just a toy; it is a fully aerobatic, stressed-skin biplane that offers the authentic experience of an Interwar RAF interceptor.

Why Is It a Legend?

• The “Mini-Fighter” Experience: It captures the aggressive yet elegant lines of the original Hawker Fury perfectly. Sitting in the open cockpit behind a windscreen, looking over the nose, you feel like an RAF pilot from 1935.

• Traditional Wood Construction: Like the original fighters of the era, the Fury II is built from spruce and birch plywood covered in fabric. It is a project for the craftsman who enjoys traditional woodworking, requiring patience and precision to build the complex curves of the fuselage.

• Fully Aerobatic: This is a pilot’s airplane. Unlike some fragile replicas, the Fury II is stressed for aerobatics (+9G / -4.5G design limits, though usually flown gentler). It loops and rolls beautifully, offering responsive, crisp handling.

• Proven Durability: Based on the earlier Currie Wot design but refined and strengthened, the Fury II has a robust structure that has stood the test of time in the UK homebuilt scene for decades.
