With a top speed of up to 345 mph, the Lancair IV is the fastest civil aviation, single engine, piston driven aircraft in the world. Turboprop Lancair aircraft can reach speeds of 370 mph.
The Lancair model P is the only aircraft of its type with a pressurized cabin.
The aircraft have been available as kits from Lancair International since 1990.
Unique to the Lancair are Fowler flaps plus high aspect ailerons that add to slow speed handling, and winglets for increased high altitude stability.
Side stick controls add to the feeling and response of flying a fighter-like aircraft, while three axis electric trim eases flight control for the pilot.
In 2014, a Lancair IV set the world's speed record for its class while flying from the North Pole to the South Pole and back again. The pilot was Bill Harrelson.
In December of 2019 a Lancair IV piloted by Bill Harrelson broke the 1961 light plane westbound around the world speed record of 8 days, 18 hours and 35 minutes set by Max Conrad in a Piper PA-23 Aztec. Harrelson, in his Lancair IV, broke the record by 19 hours and 28 minutes.
Some 360 Lancair aircraft kits were built of which 110 were for Lancair IV aircraft and 250 Lancair IV model P aircraft before production ended in 2012.
In July 2016 it was announced that part of Lancair would split from the company to sell kits of the Lancair Evolution under the name Evolution Aircraft. The Evolution is a pressurized aircraft that can be powered by either piston or turboprop power. As of this writing it appears that Evolution Aircraft is out of business and the Evolution aircraft is no longer in production.
The remainder of the company, Lancair International, supports the 320/360, IV, IV-P, ES and Legacy models as well as continuing development of upgrades and new aircraft models.
Wendell Hostetler has plans for the RC Lancair IV with a 100 in. wingspan and 83 in. length. It should be powered by 3.0 c.i.d. or larger engines and weighs about 22 lbs. ready to fly.
The RC Lancair IV from East R/C is an ARF with a fiberglass fuselage, a wingspan of 61 in. and a length of 50 1/2 in. Power can come from .46 to .50 two stroke or .52 to .65 four stroke engines. Weight, ready to fly, is about 5 1/2 lbs.
