Steven Bailey of Mistral Aviation is interviewed at Aero Friedrichshafen at the launch of the new Robin model. In this video he explains how the DR400 design has evolved into the DR401.

The Oratex wing covering has since been replaced by the Swiftwing, which comprises a 0·6 mm laminar on the upper surface of the wing, giving improved aerodynamics, a beautiful smooth surface and even better durability.

Join us for a short flight in the Robin DR401 and see some of the features of the aeroplane that combine to make it a superior choice.

Wood has key advantages over metal and composites: high strength to mass ratio, corrosion free, stable under UV light and with no fatigue life.

Six different woods and 12 varieties of ply are used in defined parts of the Robin aerostructure; each type has specific characteristics that make it suitable for a particular application.

After inspection, measurement of hardness and drying, the wood is cut, then transferred through the building to be sanded, planed, shaped and glued. The precise joins fixed with Cascophen G-1131 glue are stronger than the wood itself. Cascophen is thermoset, impervious to high temperatures and stable down to -40°C, making the aircraft suitable for use almost anywhere in the world.

Whilst wood is the star material of the Robin, the aeroplane would not reach the sky without metal!

Cutting, milling, drilling, bending and welding; all the metal components of the aircraft from instrument panel to undercarriage, from fuel tanks to exhaust systems, are fabricated in the Robin metalwork shop.

Painting protects the structure and provides a beautiful, durable finish.

Meticulous surface preparation and patience and care in application means that the process can take up to 250 hours to complete.

In addition to the range of standard designs, the client can specify a fully customised layout if desired.

Seatings and interior trim are the saddlers remit.

Working with fabrics or leather, Robin's saddler crafts a luxurious interior to the client's specification.

The assembly hall is where all the parts finally come together; fuselage, engine, interior and avionics; a multitude of individual skills at work.

Preflighting the Robin is a straightforward process that takes only a few minutes.

Except where wing-root tanks are fitted, there are only a maximum of three fuel drains and the vertical placement of the filler caps makes water ingress extremely unlikely; but we always check to be sure!

Every aircraft goes through a series of test flights to check all its systems and flight characteristics. Only after the test pilots are completely satisfied will the aircraft be released to service.

The next day, after the ARC application has been filed, a new aeroplane can be delivered to the client's airfield to await its C of A.

The luggage compartment is about 334 litres, allowing two Brompton bicycles and several bags to be loaded simultaneously. Also, the entire rear seat is easily removable to reveal a huge additional loading area if needed.

We have a long seat post on one of our Bromptons, so we prefer to replace the long post with a cut-down post to lock the frame for loading and unloading.

Brimpton is a neat rural grass field in West Berkshire, with an excellent pub / restaurant (The Hind's Head) about 0·8 miles away.

Brimpton is within the Aldermaston restricted area R101, so be sure to get prior permission before landing there.

Abergavenny is a friendly field located in lovely countryside just inside the south-east Welsh border.

An excellent pub / restaurant (The Hardwick) is adjacent to the north end of the runway.

Be aware of the line of trees on the western edge of the runway and the requirement to avoid the house to the south. Circuits are to the west.

A very well maintained grass field in Wiltshire with on-site restaurant and country store.

Residents warn of the possibility of wind shear if the wind is not aligned with the runway.

Weybourne is famous for being the smallest RAF airfield of WW II and the home to the Muckleburgh Military Collection.

It seems to be mostly used by microlights and STOL aircraft. It is comfortably within the capabilities of the DR401 155CDI with appropriate care.

A few miles north-east of Peterborough Connington, the grass field of Wallis is just across the road from the excellent Dog in a Doublet pub / restaurant.

There are trees at the western threshold and bumps at the western end of the runway.
