Maule has a couple of new airplanes for the new year – well, two slightly different models on the same airframe, anyway. The M-4 180V S2 and S4 are typical Maule: STOL performance, metal-winged tube-and-fabric construction, and an emphasis on cargo space. The big difference between the two it the seating. The S2 model is a side-by-side two-seater and the S4 can carry a pilot plus three.
Max gross weight for both models is 2,300 pounds, giving the S2 a useful load of 950 pounds (925 lbs. for the S4). The M-4 180V gets through the air with the 180hp Lycoming O-360 and a 76” constant speed Hartzell prop.
Performance is also the same for both M-4 models and it’s what you might expect from a rugged little tail dragger. Cruise at 75% power will get you around 116kts. Stall in landing configuration is down around 37kts. Average range with a 30-minute reserve is 477nm with the two standard 21.5 gallon tanks. The optional long-range tanks (73 useable gallons total) will stretch that to 810nm. An STC is available for unleaded Mogas.
Avionics are analog for the most part. The exception is the J.P Instruments EDM-900 Engine Data Management System glass engine display. Cargo capacity can be as much as 38 cubic feet, though that requires removing the rear seats in the S4 version. Access to cargo space is two clam-shell style doors to allow for stowing longer items. Base price is $199,900 for the S2 and $203,900 for the S4.
