The concept for the Martin Mauler (officially Martin AM-1 Mauler) originated in 1943. Based on combat experience, the U.S. Navy requested a carrier based aircraft that could be used both as a conventional bomber and a torpedo bomber. It was to have fighter plane-like speed and a crew of one pilot. For reliability and simplicity of design it would carry its ordnance externally.
The aircraft that Martin proposed was designed around the most powerful piston engine of its time, a radial that produced some 3,000 h.p.
Due to its size a hydraulic system needed to be developed to control the Martin Mauler. This delayed its production. A prototype aircraft took to the sky in August of 1944, but development problems delayed its deployment until well after the end of World War II.
The Martin Mauler had an ordnance capacity greater than any other single engine aircraft of its time. However, high torque pull from the engine made it particularly unsuitable for aircraft carrier take offs and landings. Higher than anticipated maintenance and reliability problems also surfaced during the deployment of the aircraft.
The Martin Mauler became operational with the U.S. Navy in March of 1948 and served on active duty through 1950. The Naval reserve flew the aircraft into 1953.
A total of 151 Martin AM-1 Mauler aircraft of all types were produced.
RC Martin Mauler
That’s Hellcat of RC Groups with his RC Martin Mauler. It has a wingspan of 69 in., weighs about 12 lbs. and is powered by a .90 OS FS engine. The model was built from Claude McCulloch plans.
The RC Martin Mauler from Huayu Hobby is an all balsa model with a wingspan of 71 in. with a length of 57 in. It needs a 26 cc gas engine for power.
The RC Martin Mauler from Fly Boys is an ARF. Wingspan is 58 in. and length is 47 in. It comes with retracts and working landing lights. Recommended power is a .61 to .75 two stroke or .91 four stroke engine.
The AMA Plans Service has two sets of plans for the RC Martin Mauler. Both have wingspans of 37 in. and are originally intended for c/l flying, but are easily converted to radio control. Plan numbers are 29205 and 15341.
Brodak has a c/l kit of a RC Martin Mauler. It is made from balsa and ply with a 46 in. wingspan and a 33 1/2 in. length. Power may come from .28 – .40 2C engines.
