A two seat, side by side, single engined, high-wing monoplane with conventional three axis control. The wing has unswept leading edge, swept forward trailing edge and constant chord, cruciform tail. Pitch control is by elevator on tail, and yaw control by fully flying rudder; roll control by half span ailerons; control inputs through stick for pitch/roll and pedals for yaw.
The wing is braced from below by struts; with a double surface wing profile. The undercarriage has three wheels in tricycle formation; no suspension on the nosewheel and bungee suspension on the main wheels. Push right go right nosewheel steering is connected to the yaw control. No brakes. An aluminium tube framework, without pod, the engine is mounted below wing driving pusher propeller.
On the two seater Aerokart 4320 the kingpost and wire used on this company’s single seaters is replaced by struts. The horizontal stabiliser, stiffened in flight and landing by cables, has the outer sections of its leading edge joined by tubes to the spars carrying the tail assembly. These tube joints form a structure of high structural integrity rather than low drag.
The 4320 has its motor mounted in front of the wing on silent bloc bushes, driving a twin bladed propeller behind the trailing edge from toothed belt reduction. The 1983 standard power pack for this aircraft was the twin cylinder in line Hirth 2701R of 43hp fitted with a tuned exhaust for each cylinder, this system having been developed by Aerokart.
The hot air from the cooling fan is fed to the carburettor and air filter by a movable flap when atmospheric conditions demand de icing and switched back at other times.
This two seater is delivered in standard form with an electric starter while retaining the capability of manual starting. Electric fuel pump and double surfacing for the wing, ailerons and tail areas, and alloy rims for the main wheels are all standard fittings on the 4320. The machine is transportable on a trailer, folded dimensions being 16.9 x 6.3 x 5.9ft (5.10 x 1.90 x 1.76m).

The A Kart 30 was developed into two other prototypes; the tandem 4320 two seater and the single seat 3315, both of which made their first flights at the beginning of summer 1982.
Aerokart continued the trials, refining and developing the machines, until that Septem¬ber, at the first European Microlight Salon at Lyon Bron, it was able to show two pre¬-production machines. The first was a single-¬seater, the type 3315 and the second was the 4320 side by side two seater. Both went on sale in November 1982, though the company has put most of its marketing effort into the Aerokart two seater. This manufacturer uses the first two digits of the type number to indicate the maximum power of the motor used, while the last two numbers indicate the wing area in square metres.
The single seater 3315 uses a Hirth 260R engine of 338 cc developing 33 hp at 7250 rpm, with a 23/1 reduction drive and a 51 inch (1.3m) two blade propeller. The type 4315 is more powerful and is fitted with a Hirth 2701R, 493cc engine developing 43hp at 6750rpm with toothed belt reduction. Of traditional configuration, these machines use of ailerons instead of spoilers, and their engine is fitted inverted in front of the wing below the level of the leading edge. It drives through the reduction drive to a shaft which crosses the wing to connect with a pusher propeller at the trailing edge. Flexible mountings absorb the vibrations caused by using such a long shaft whilst retaining for the Aerokart the advan¬tages of prop wash over the tail surfaces and a well cooled engine.
The machine is trans¬portable on a road trailer.
