The M-14 features a single main rotor, a two-seats-in a tandem open cockpit with a windshield, tricycle landing gear with wheel pants and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 1000NaN0 Rotax 912S engine in pusher configuration. The turbocharged 1150NaN0 Rotax 914 powerplant is optional.
The aircraft fuselage is made from TIG-welded 4130 steel tubing, while the cockpit fairing is fibreglass. Its 8.231NaN1 diameter composite rotor has a chord of 221NaN1 and is manufactured in house by Magni Gyro. The propeller is a three-bladed carbon fibre, ground adjustable type. Electric trim is standard equipment, as is a Flydat digital engine monitor.

The pilot's seat includes an integral fuel tank that provides three hours endurance. The aircraft has an empty weight of 2440NaN0 and a gross weight of 5500NaN0, giving a useful load of 3060NaN0.[2]
