The Mitsubishi G4M Betty was the main Japanese bomber of World War II. It was designed to have a 2,000 mile range while fully loaded with ordnance. To do that, designers lightened the aircraft by omitting armor to protect the crew and vital aircraft parts. In addition, the fuel tanks were not self sealing. This made the Betty easy prey for fighter aircraft.

Prototypes first flew in late 1939. The aircraft had few faults which needed correcting and full scale production began in late 1940. By mid 1941 the bombers were being deployed to front line units.

The aircraft received more powerful and reliable engines, better streamlining, and larger tailplanes with successive models. They were able to fly faster and at higher altitudes.

In early 1943 some Mitsubishi G4M Betty aircraft were adapted as torpedo bombers. They had some success, sinking the cruiser Chicago and scoring hits on the aircraft carrier Intrepid.

In 1944, Betty bombers were finally fitted with armour and self sealing fuel tanks. However, by that time production had slowed, and only sixty updated aircraft were produced before the war ended.

In the last days of the war, Betty bombers were adapted to carry the MXY-7 Ohka kamikaze manned rocket. Due to the weight and drag from the rockets slung under their bellies, they made easy targets for intercepting fighters.

A total of 2,416 Mitsubishi G4M Betty aircraft were produced before the end of the war.

In the photo immediately above is the rc giant scale Mitsubishi G4M Betty for sale from Quality Fiberglass. It has a wingspan of 127" and a length of 98".  Construction materials are a fiberglass fuse with foam core wings.  To power it you will need a pair of .25 to .35 cc engines.  Upon completion, all up weight should be 30 to 35 lbs.

The first photo below is of the "stand back and squint scale" rc Betty airplane for sale by Nitro Planes. For reasons known only to the manufacturer, the radio control airplane has an American paint scheme and markings.  Some Mitsubishi G4M Betty aircraft were captured by the allies and actually had similar markings, so this may be the reason. However,  no Betty aircraft were painted with invasion stripes by the Americans.  It has a wingspan of 19" and a length of 15". Control is with a two channel radio. Turning is done by engine power differential.  To climb or lower the rc airplane, power is applied or reduced. It is a foamy.  Many retail carry this rc airplane, with a large difference in pricing.  We suggest you shop around for the best price if you are interested in this type of radio control airplane.

In the second photo below is the 1/72 plastic scale model Mitsubishi G4M Betty airplane built by Bill Shatman from a Hasegawa kit.  The model kit contains 56 pieces.  Michael Hays, who reviewed the plastic scale model kit, appreciates the panel lines and rivet details.  However, he wishes for more cockpit, nose, interior and under carriage details.

The last photo on this page is of the 1/48 plastic scale model G4M Betty airplane built by Ian Robertson. It has a wing span of 20" and a length of 17".  Ian highly recommends this model airplane.
