Champion Lancer
The Champion 402 Lancer is a twin-engine trainer produced by Champion Aircraft, based on the tricycle gear Champion 7FC Tri-Traveler, but powered by two wing-mounted Continental O-200-A engines.〔 The Lancer first flew in 1961 and production began in 1963. The Lancer seats two in a tandem configuration with dual flight controls; the pilot in command or student pilot normally occupies the front seat.
==Design and development==
The Lancer achieved its goal of being the least expensive American-built twin engine airplane. Other design goals included simplicity, ease of maintenance, low operating costs, and the ability to operate from rough or unimproved strips. The high wing and high engine position give good propeller clearance in achieving that last goal. The Lancer is of metal tube construction with fiberglass covering and has fixed landing gear and propellers.〔Plane and Pilot: ''1978 Aircraft Directory'', page 95.

The Lancer was designed specifically for flight schools seeking an inexpensive way to train students for a multi-engine rating, a role in which the craft's modest performance and payload were anticipated to matter little.〔 To increase its appeal to flight schools, the Lancer was equipped with a mock landing gear retraction switch that operates green “safe” and red “unsafe” lights in the cockpit, allowing a student pilot to feign operation of imaginary "retractable" (it was permanently fixed) landing gear on takeoff and landing during instructional flights. In a peculiar combination, the front seat was equipped with a control yoke, while the rear-seat pilot had a centre stick. Both seats were equipped with engine controls mounted overhead, with solo flight being performed from the front seat. Braking was controlled with a lever on the right-hand side of the front-seat instrument panel; differential braking was not possible, and no brake controls were provided for the rear-seat pilot.〔〔〔 Other features included single-slotted wing flaps with 4 adjustment positions, and pilot-adjustable trim tabs for the elevator and rudder;〔 elevator trim was adjusted using a sidewall-mounted lever.〔
The prototype Lancer underwent development between 1961 and the start of production in 1963. The changes included relocating the engine nacelles to their final position above the wing,〔 strengthening the wings to accommodate the engines, and redesigning the empennage to provide for twin-engine control requirements.〔 The Federal Aviation Administration type certificate was approved on 7 March 1963.
