(eXperimental Ducting Lifting Body)
A true lifting body by definition, The X-DLD-1 was the first to be built in the X series as a wide body for load baring and stability. The tail fin configuration was developed with this model extensively and proved to be the stabling factor with testing, since lifting bodies have a history of unstable roll. With the new tail fin configuration many new possibilities have evolved.
(eXperimental Ducting Lifting Body)
The X series is about investigating lifting body configurations. This particular concept did evolve from several generation beginning with the Locus a short stubby canard type aircraft. Over time this had many innovations to improve the characteristics in being the canard in water. One particular concept holds true to the existing development, and that is the FireFly was exploited though the DragonSleigh and became this new concept. Until January 2007 a unique modification to simplify construction using facet design a wedge principles of a paper airplane was introduced inverting the tail fin in a downward positions has become the driving signature of the X-DLB series
