The Blue Tail Hawk is my on-going ultralight study project. I wanted an ultralight that meets the following goals:    low initial cost,   scratch built,   fuel efficient,   enough speed and range for cross country flying,    low drag,    low weight,    FAA Part 103 compliant,    comfortable,    good visibiity down to the ground,    easy to fly,    use a small four stroke engine.  

Some good flying was done with a 26hp Rotax 277 and 3-blade Power Fin prop. With the long wings it did quite well that way.

Due to the success of the Generac v-twin engine on my Thunder Gull, I re-worked the Blue Tail Hawk to accomodate the Generac engine. I needed to get weight out of the tail to keep the center of gravity near the center of the range. The new tail plane is composite, and in a T-tail configuration which is lighter. And with more thrust from the Generac, I am able to operate the Blue Tail Hawk with shorter wings.

The status of the Blue Tail Hawk project as of early 2010 is that it has been set aside while I vigorously pursue my electric powered Red Tail Hawk project.
