The Super Albatross was created from a Baby Albatross fuselage pod and tail boom. The wings used the outer panels of the Senior Albatross. The resulting aircraft was of wooden construction, with the wings and tail surfaces covered in aircraft fabric. The tail boom is a metal tube.
Only two examples were constructed. The first was built by Bowlus and features an all-flying horizontal stabilizer. The second was built by Frank Kelsey and has a fixed horizontal stabilizer and flaps in addition to spoilers.
The Super Albatross from Jilles Smits is modelled at a scale of 1/2.5 The prototype to be very soon.
