The RAF Defiant, produced by Boulton Paul, was the first British fighter aircraft with more than two machine guns.

It had a unique placement of its four 7.7 mm machine guns.  Rather than being placed in a fixed position firing forward, the machine guns were placed in a turret behind the pilot in the rear of the canopy. This was similar to the turret on top of bomber aircraft.

The fighter achieved some initial success when first encountering enemy fighters. However, fighter aircraft were quick to exploit a weakness in the placement of the turret. It was that they could not be fired upon when attacking from in front of and below the aircraft. Also, the speed and maneuverability of the RAF Defiant was not equal to that of modern fighter aircraft. Defiant aircraft were not capable of besting the latest fighters of the Luftwaffe.

However, the RAF Defiant achieved a good deal of success when equipped with radar and used as a night fighter. It went on to become the most successful British night fighter of World War II. Eventually it equipped thirteen RAF squadrons.

A total of 1,064 RAF Defiant aircraft were produced.

RAF Defiant - Flyboy

Immediately above is a picture of the RAF Defiant by Flyboy Models. It has wings which span a total of 61 1/2". The fuselage is 54" long. You may use from a .61 to .75 two stroke or a .91 four stroke engine for power.

Pictured immediately below is the RAF Defiant that was converted from a free flight kit by Guga of RC Groups. It has a wingspan of 44" and a length of 33". It is powered with a CD ROM motor geared 5.3:1 turning a 10 x 4 propeller.

The next picture below is also of a RAF Defiant Free Flight kit that can be converted to a radio control airplane. This one is from a balsa Easy Build Models kit. It has a wingspan of 30" and is 1/16 scale.

The bottom picture is of the RAF Defiant from YH Model. It has a wingspan of 73". The fuselage is 66 1/2" long. It uses balsa and ply as the construction materials. Recommended power is a 1.20 four stroke engine.

Bob's Aircraft Documentation has three view drawings which may help with the building of a RAF Defiant.
