The Lake LA-250 Renegade is a six-seat amphibious utility aircraft produced in the United States by Lake Aircraft since 1982.[1]

Design and development

[edit]

The Renegade is a lengthened and more powerful version of the Lake Buccaneer. They share the Buccaneer's type certificate, and Buccaneer production was terminated.[2] In turn, it gave rise to a number of variants, including the militarised LA-250 Seawolf, the turbocharged LA-270 Turbo Renegade, and the LA-270 Seafury optimised for marine environments.[1][2] Like the Buccaneer, it is a conventional mid-wing design with retractable tricycle undercarriage and a single engine mounted in pusher configuration in a pod on a pylon above the fuselage.[3]

The Seawolf version was designed for light maritime patrol duties and features a hardpoint under each wing to carry external stores, including bombs, rocket pods, gun pods, or rescue equipment.[3] Provision for a radar unit was made on the forward end of the engine pod.[3][4] The Seafury includes improved anti-corrosion measures and a hardened interior to improve its serviceability in saltwater environments, as well as a storage compartment carrying survival gear.[5]

Operational history

[edit]

On August 31, 1988, Peter Foster and Robert Mann departed Sanford Seacoast Regional Airport in a Lake Turbo Renegade, flying to a maximum altitude of 24,600 feet and then leveling off at 24,500 feet. This flight set new world records for altitude and sustained flight at altitude for single-engine amphibians, FAI class C-3C-08.[6][7]

A year later on November 2, 1989, two more flights departed from Bauneg Beg Lake in Sanford, Maine, setting four more world records for single-engine seaplanes. In the first flight of the day, Robert Mann flew a Lake Turbo Renegade N270TL with co-pilot Gordon Collins to an altitude of 25,500 feet. They were able to sustain this altitude, setting two records for FAI class C-2C-08.[8][9] Later in the day, Robert Mann flew N250L solo from Bauneg Beg Lake to an initial altitude of 27,300 feet, and then leveling off at a sustained altitude of 27,100 feet for two more world records in FAI class C-2B-08.[10][11]
