It all began with ultralights

Aviation began with ultralight aircraft. The

first heavier-than-air powered flying

machine was the direct ancestor of the modern

fixed-wing ultralight and its bigger light

sport aircraft (LSA) brother. Nevertheless, it

took nearly 100 years for ultralights to

became established as a class in their own

right.

In common with many recent

designs, the Corvus Corone is

made in two versions, one for

the European microlight market

and another for US SLA buyers.

This low-wing all-composite aircraft

originates from Hungary.

T

he Wright Brothers’ Flyer weighed a mere 340kg. Its

12hp motor was just powerful enough to launch the

Flyer into history on 17 December 1903 at Kitty Hawk

in North Carolina, as the first aeroplane to fly controlled under

its own power. The flight was made by Orville Wright, covering

307m in 12 seconds. On the same day Wilbur Wright flew 59

seconds, covering a distance of 260m.

Their canard biplane has a wingspan of 12.3m, is 6.4m long

and 2.8m high. It has a muslin-covered wooden frame and the pilot adopts a prone position on the lower mainplane.

The history of ultralight aircraft can trace its roots back even further, to 14 August 1901 when it was claimed that

Gustave Whitehead (who had changed his name from Gustav Weisskopf) flew half a mile in his monoplane in

Bridgeport, Connecticut. Whitehead was disappointed that his flights were always of short duration, which is probably

why he remained unknown. He once said to his assistant: ‘These flights are all no good, because they are of

insufficient duration. We are not yet able to fly anywhere we want. Flying will not become significant until we can fly

when and where we want at any time.’

His wish became reality much sooner than expected, thanks to the First World War. From 1914, military demands

pushed aviation manufacture and operation into the industrial age. Most WWI aircraft would today be classified as

ultralight or LSA, and they were certainly capable of flying almost anywhere, at any time.

After WWI, aircraft became progressively bigger, faster and heavier, culminating in the astonishing Antonov An-225,

a strategic heavy lifting cargo aircraft with a gross weight of 600 metric tons. Built in Ukraine, the six-engined An-

225 first flew in December 1989.

However, not everyone followed the ‘bigger and heavier’ route and as long ago as the 1920s there was a demand

for aircraft that were small, lightweight and economic.

Hans Klemm was one designer who catered for this demand. His Klemm L20 had a plywood-covered wooden airframe

and in 1928-29 was flown around the world by 22 year-old Friedrich Koenig-Warthausen. Its 20hp engine

was so economical that the L20 could carry enough fuel for 20 hours flying – a genuine LSA which, incidentally,

weighed about the same as the Wright Flyer.

Today, ultralights, microlights and light sport aircraft (LSA) are well established in their respective categories and

come in an amazing range of shapes and sizes. They extend from the simplest and cheapest ultralight kit with a

fabric-covered aluminium tube frame for less than $4000, to a fully composite cross-country machine costing over

$100,000. There are WWI scale replicas and Piper Cub lookalikes by the dozen. Some are capable of 200mph,

while others are so slow that they can easily land and take off on the short side of a football field without having to

backtrack.

The range is so huge that all you have to do is decide which aircraft on the next 50+ pages comes closest to your

dream machine. And if it seems unaffordable ready to fly, remember that many machines come in kit or even in

plan form. Dare to dream, just as the Wright Brothers did.

CLASS OF REGULATION

Shows the lightest class of airworthiness regulation for which the aircraft is eligible. In order of ascending

weight these are:

US-UL US Ultralight category, one seat and up to 115kg empty weight, maximum level flight speed 102km/h

(deregulated single-seaters in the UK operate under similar rules)

FAI-ML European Microlight category, one or two seats, up to 472.5kg MTOW, stall speed maximum 65km/h

US-LSA US Light Sport Aircraft category, one or two seats, MTOW weight 600kg, stall speed maximum 82km/h

The definitions above are not exhaustive. For example, retractable undercarriages, variable-pitch propellors

and multiple engines are not allowed under US-LSA, but are all permitted under FAI-ML. Generally however,

it may be assumed that an aircraft eligible for one class is also eligible for any heavier classes.

Please note that eligibility for a class of regulation is not the same as certification under those regulations.

Where we know that certification has been achieved, we quote the standard(s) in the data panel.

In the final analysis, however, it is up to the reader to ascertain whether a particular machine can legally be

used in a particular place and manner.

3XTRIM

Designed for the European market, this aircraft uses high-quality laminate construction. It’s good to look at and very

straightforward to fly. The machine is also available with a Rotax 912 or a Jabiru 2200 of 80hp. A certified version to

JAR VLA rules rated to 550kg is also offered.

The Chrysalin is entirely built in composite glassfibre / vinylester resin sandwich construction. This is one reason why its

weight is quite modest, for an aircraft of its size. The wings fold very quickly for storage or trailering.

Though also active in the paraplane market, ASAP has been in the business of making three-axis microlights for a very

long time. This design uses traditional tube-and-fabric construction with a pusher engine and tandem seating. The wing

is swept back and features full-span ailerons. We list it here with a Rotax 582 but a Rotax 503 and an HKS 700 are

also available. Price excludes engine.
