The Rocky Mountain Wings Ridge Runner is a family of American high wing, strut-braced, single engine, conventional landing gear aircraft that were designed by Stace Schrader and are produced by Rocky Mountain Wings of Nampa, Idaho for amateur construction.[1][2][3][4][5][6][7][8]

Design and development

Introduced at Airventure, Oshkosh, Wisconsin in July 2000, the first Ridge Runner was a single seater designed as an FAR 103 Ultralight Vehicles compliant aircraft that would have an empty weight within that category's {{convert|254|lb|kg|0|abbr=on}} empty weight limit.[1][2][3][4][5][6]

The designer, Stace Schrader was formerly involved with Avid Aircraft, the Denney Kitfox and Sky Raider LLC designs, all similar aircraft. The resulting aircraft was described by reviewer Andre Cliche as "a clone identical to its predecessors except for a few details like, for example the type of ailerons and balloon tires for rough terrain operations."[1]

The aircraft has an optional powder coated 4130 steel tube frame fuselage covered in doped fabric. The wing is constructed with aluminium tube spars and is also fabric-covered. The kit includes many pre-fabricated parts, including the wing ribs, seat belts and shoulder harnesses, wheels and tires. The manufacturer estimates the construction time as 250–600 hours, depending on the options selected and builder experience.[1][2][3][4][5][6][9]

The Ridge Runner 1 requires a very light engine to remain under {{convert|254|lb|kg|0|abbr=on}} empty weight and the specified engine remains the out-of-production {{convert|28|hp|kW|0|abbr=on}} Rotax 277.[1]

Variants

Ridge Runner Model 1 Ultralight

Original model, a single seat, FAR 103 compliant aircraft, with a {{convert|247|lb|kg|0|abbr=on}} empty weight when equipped with the out-of-production {{convert|28|hp|kW|0|abbr=on}} Rotax 277 engine, or alternatively an experimental light sport aircraft. Acceptable power range {{convert|20|to|80|hp|kW|0|abbr=on}}.[1][2][4][5][10][11]

Ridge Runner Model 2

Light sport or amateur-built version, similar to the Model 1, but with a jump seat added, though without dual controls, and an empty weight increased to {{convert|350|lb|kg|0|abbr=on}}, gross weight {{convert|950|lb|kg|0|abbr=on}}. Acceptable power range {{convert|28|to|52|hp|kW|0|abbr=on}}. The manufacturer says of this model: "Ridge Runner II is not a full two place. It has a small jump seat or cargo area"[1][3][10][12][13]

Ridge Runner Model 3

Light sport or amateur-built version, with two seats in tandem with dual controls. Standard engine is the Rotax 503 of {{convert|52|hp|kW|0|abbr=on}}. Acceptable power range {{convert|40|to|100|hp|kW|0|abbr=on}}.[4][5][10][8][14]

Ridge Runner Model 4

Light sport or amateur-built version, with two seats in side-by-side configuration with dual controls. Standard engine is the Rotax 912 of {{convert|80|hp|kW|0|abbr=on}}. Acceptable power range {{convert|45|to|120|hp|kW|0|abbr=on}}.[7]
