Prototype and subsequent aircraft converted from Model 200s and re-serialled; 23 delivered.
Although the prototype was to have a dihedral of 3 it was intended that this would be increased in subsequent aircraft.
The changes were incorporated in subsequent aircraft as they were built.
To designate a series of serial numbers, the slash is used, as in 85-1001/1050 for the first fifty subsequent aircraft.
These features proved unsuccessful and were omitted from subsequent aircraft.
They have been used on subsequent aircraft, including:
As with all subsequent aircraft, the fuselage was lengthened by 2 ft (0.6 m).
Unexpectedly, subsequent mass-produced aircraft were found to be 10-12% heavier than the prototype which significantly hampered performance.
The second and subsequent aircraft were built at Southampton Airport after the company moved in 1937.
Similar to V-3 but with integrated spoilers which were standard on subsequent aircraft.
