Maule M-7

The Maule M-7 is a family of single-engine light aircraft that has been manufactured in the United States since the mid-1980s.[1][2][3][4]
Design and development
Based on the Maule M-4, it is a high-wing, strut-braced monoplane of conventional configuration, available with tailwheel or optional tricycle wheeled undercarriage[5] and frequently used as a seaplane with twin pontoons. The basic M-7 has a longer cabin than its predecessors the M5 & M6, with two seats in front, a bench seat for up to three passengers behind them, and (like the M-6) an optional third row of "kiddie seats" at the rear.[6] Extra cabin windows can be fitted if the "kiddie seats" are to be used. The MX-7 uses the same fuselage as the M-6,which is a modified M5 fuselage but the same wing span as the M-5,[4][6] and incorporates the increased fuel tankage, hoerner style wing tip and five-position flaps designed for the M-7.[7]
The M-7 family has been produced both with piston and turboprop engines.[4][6][8]
