When it was available the aircraft was supplied in the form of plans for amateur construction, with some pre-fabricated parts available.

[1][2][3] The Firebolt was developed from the Steen Skybolt and features a biplane layout with interplane struts, cabane struts and flying wires, a two-seats-in-tandem open, or optionally, enclosed cockpit under a bubble canopy that slides back, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.

With that engine the aircraft has a cruise speed of 202 mph (325 km/h) and an initial climb rate of 4,000 ft/min (20 m/s).

With full fuel of 39 U.S. gallons (150 L; 32 imp gal) the payload for the pilot, passenger and baggage is 441 lb (200 kg).
