The Double Eagle Airplane is a “plans built” design powered by the widely available stock VW engine, that will carry 2 people with a useful load around 515 Lbs. It can be built and flown under the Light Sport Aircraft Category. This is a strong and simple airplane designed using traditional and proven aviation tubular steel technology. It is easy to build and there has developed around it a strong core of builders that offer help and support for building the aircraft. There is also a full kit developed by John Bolding in consultation with the designer that makes building this design even faster.
The Double Eagle Aircraft is a welded fuselage made of aircraft tubing and represents one of the strongest and lightest 2 place airframes on the market today. The design was originally created as a “super” legal eagle for a heavy friend of Leonard’s. When this friend died before the project was finished, Leonard converted it into an Ultralight Trainer for pilots wanting instruction on flying the Legal Eagle. When the FAA changed the rules creating the LSA category this design was certified as a LSA homebuilt design.
Leonard developed the Double Eagle as his 11th airplane project as an outgrowth of the need to have a trainer for his very popular Legal Eagle Ultralight. The Double Eagle started to form up in 2002 and was first widely seen at the 2003 Oshkosh show. A repeat performance in 2004 broadened its popularity, and many kits started out the door.
“DE” was getting special treatment in 2007 because of an invitation that Leonard Received from the EAA to display the Double Eagle at the Air Venture 2007 Air Show. It seems that EAA membership has been asking for an affordable Light Sport Aircraft and most others while fine airplanes tend to run upwards of $50,000. Since the Double Eagle can be certified in this category and costs under 10-12 thousand dollars (even paying retail, and getting some building help), it is very affordable the invite went out. The aircraft is sporting a new Culver prop and has many cosmetic improvements and tweaks in celebration of the event.

Designed by Philippe Prevot in Toulouse, France, the aim was to produce a high performance microlight airplane of the simplest possible construction to be assembled, inspected and repaired by anybody. Using the geometric strength of a triangle, he patented his cabin frame design. Structural studies were done by the most ENSICA aeronautical school, that confirmed both the strength and light weight of the craft using only straight tubes and no welding.
Designed to utilise only straight 2017/2024 aluminium tube with no welding, it is of all alloy construction with tail covered in dacron cloth and the wings and fuselage section come as pre sewn socks of that are slid into place then tightened. The tricycle undercarriage has hydraulic disc brakes.
Ninety-eight Sky Rangers were then manufactured in France from 1992 to 1997 under license by SYNAIRGIE.
In 1998 manufacture of the V.FUN model of the Skyranger-2, under the French license from Best Off, was moved to AEROS in the Ukraine. The V.FUN-CLASSIC aircraft model with a tail dragger option is available.
Aeros aviation engineers who before worked for Antonov Design Bureau added to the design and sales were still made by Best Off as well.
Powered by a Simonini from Italy, the 92hp, 6200 rpm in line 2 stroke, is coupled to a 3 blade, 72 inch propeller. The engine has 2 large mufflers fitted making it very quiet in the cockpit and from the ground. It cruises at 80 mph using 10 litres /hr with a four hour endurance.
The Skyranger climbing rate is from 3 m/s with 50 hp to near 6 m/s with 80 hp and two people need only 20 minutes to fold the wings.
Starting from 2004, the V.MAX basic model with lower wing fence was produced, which fully complies with BCAR’S standards.

After a period of crisis, the Best Off company opened its doors in 1998 but produced only one model; the SkyRanger.
Involved in aviation almost all his life, Harold Best’s earliest flight training came in a World War I Avro 504 trainer. He built his first aircraft, a Mignet HM-14 Flying Flea, in 1935 while still a schoolboy and soon became involved with the British homebuilt movement, assisting in the development of several designs that were available prior to World War II.
During the war, Harold was involved in photo reconnaissance and converting Spitfires for photo recon service. In1942 he was secretly dropped into occupied France and worked with the French Resistance to sabotage German aircraft production in that country. After the war, he helped found the Popular Flying Association in the U.K. and maintained his close ties to the very active French amateur built aircraft movement. This connection was extremely valuable during his service with the British Air Registration Board, now the Civil Aviation Authority, where he was able to transfer the French acceptance of amateur built aircraft into the U.K.’s then restrictive regulations.
England’s Harold Best-Devereux, who was best known to U.S. EAAers as the eloquent master of ceremonies for the evening programs at Oshkosh until his untimely death from cancer in July of 1985, played a far more important role in the international affairs of UK homebuilders. The European Director of EAA for over 20 years, Harold worked tirelessly to make it possible for Europeans to build and fly their own aircraft, to make rules less restrictive in those nations that did allow homebuilding and to bring sport pilots of every nation together. Fluent in French, he and EAA Founder Paul Poberezny traveled extensively in France and other countries helping establish the legitimacy of amateur built aircraft throughout Europe. For these and other achievements, Harold was awarded the prestigious Paul Tissandier Diploma by the Federation Aeronautique Internationale and, although a citizen of the United Kingdom, was elected a member of a select group of French aviation pioneers.
An active pilot until his death, Harold owned a number of aircraft over the years, including a Tailwind he bought in the U.S. One of his most treasured aviation experiences came in the summer of 1977 when he and his son, Igor, flew a 1937 Miles Whitney Straight from Halifax, N.S. to Lake Tahoe, CA, with a stop at Oshkosh to participate in that year’s EAA Convention. At the time of his death, Harold was rebuilding a 1947 Miles Messenger and extensively researching the life of Henri Mignet.
Single seat single engined high wing monoplane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by elevator on tail; yaw control by fin mounted rudder; roll control by quarter-span spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile Clark Y derived; 100% double surface. Undercarriage has three wheels in tail dragger formation; no suspension on tailwheel and axle flex suspension on main wheels. Push right go right tailwheel steering connected to yaw control. No brakes. Aluminium tube framework without pod. Engine mounted below wing driving pusher propeller. All aluminium tubing to British HT3OTF specification.
In February 1982 the Besam partnership was advertising a full three axis control microlight promising that it would be available ‘soon’. Some explanation of these absences was provided in July when Besam announced that its premises had been first burgled and then set on fire, destroying the working drawings and damaging the prototype to the point where it was easier and safer to start again from scratch.
