Double Eagle™ LSA Details and Specifications

The Double Eagle™ LSA is a welded fuselage made of aircraft tubing and represents one of the strongest and lightest 2 place airframes on the market today. Designed by L.E. Milholland as his 11th project, 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. Individuals who apply themselves can build this airplane in 7-12 months, faster if they secure the materials kits available from John Bolding. Cost for the design is between $7 and $15 thousand dollars depending on your scrounging ability, and the use of parts kits. However, the prototype was built for much less.

Power is supplied by the reliable V.W 4 Cylinder Engine. These engines are widely available and a conversion kit is produced by Scott Kastler 520-723-5203 and also by Great Plains Aircraft Supply 800-922-6507. Both Sources have engines and parts. Welded Fuselages and airplane parts are available from John Bolding. Neither John or Leonard sell complete kits due to liability issues and as builders must still meet the 51% rule, but a great deal of help is available for parties wanting to do fast build projects. There is also an active builders community and email distribution list. Leonard sells a shrink fit prop hub for these engines that is on the website.

Editors Note: Absolute specifications are based on the plans and minor variations may be involved. This information should be used as a guide only and is not warranted for any other use public or private. Leonard Milholland as the designer reserves to himself final interpretation of any and all specifications for the aircraft outside of those submitted to the FAA and included in the plans. Since each builder may make variations in the plans and also possess varying skills in the manufacture of the aircraft the final determination of airworthyness is up to the builder and the inspection process involved for certification. No other warrantee is expressed or implied and the designers absolute, complete and total liability for any disputes it the prompt refund of the amounts actually paid for plans and video materials.

These are photo's of  the Double Eagle™ LSA by L. E. Milholland. This aircraft is now complete. Photo's by Leonard Milholland and Gail Simmons Gibson, (his daughter). This prototype will be shown at Oshkosh in 2003.  The design goal was exceeded bring this aircraft dry weight in at 385 lbs (airframe and engine) thus allowing for two large people, and a full 10 gallon fuel load under the 900 lbs gross load.

"I would ask that builders considering the Double Eagle ™ start with the engine because the design is simple. The Double Eagle uses a full VW engine, with modified cylinders producing a useful power of roughly 60 HP." Leonard Milholland.
