Fleetwings Sea Bird (or Seabird). Free flght scale model amphibious seaplane. For Lindberg Hornet ignition engine.
Quote: "A Model Amphibian. To our reader-builders seeking the unusual, we offer an amphibian as this month's gas model. It is patterned after the Fleetwings. By Paul W Lindberg.
A NUMBER of requests have been sent in for an amphibian gas model. After going through our files we ran across this particular design which we thought would make a very good gas model. This particular model is equipped with shock absorbing landing gear which may be retracted for seaplane work. We are sure you will find this model very interesting to build as well as to fly over week-ends. The model has been painted red with silver trim.
Construction of Fuselage: This type of fuselage is built somewhat different than the conventional flying plane type. It will first be necessary to cut all the formers to exact size. The halves of fuselage formers are cemented together to receive all stringers as well as reinforcement members.
The motor nacelle is constructed some-what similar to the fuselage. The cowl ring is turned up fruit solid balsa using stiff paper. Nacelle struts are made from 1/16 OD piano wire faired with 1/16 thick balsa. It is very important that these be securely tied into nacelle and fuselage.
Construction of Landing Gear: We have gone to great detail in describing the landing gear on the plan. If one will study its construction very closely no trouble should be encountered here. Springs within shock struts may be made from ordinary piano wire wrapped around a nail. The model may be built with or without the retractable landing gear, depending upon your taste.
Construction of Elevator and Rudder: The rudder and elevator both are con-structed of the flat section type. No camber is built into them as we have found the former type very satisfactory. Build these upon a flat surface to prevent any warping.
Construction of Wings: From 1/16 stock make all the wing ribs with the exception of the two root ribs which are 1/8 in thickness. Take special precaution in shaping leading edge so that you obtain a very uniform edge. This will add greatly to the flying qualities. Do not omit any of the diagonal 1/8 square compression members. Wing tips are also of 1/8 sheet balsa.
Covering the Model: In covering the fuselage of the model do not attempt to cover with too large pieces as this will only result in a poorly covered model. Cover only one section at a time for best results.
Wings and tail surfaces may be cov-ered in large pieces as no irregular curves are encountered here. In order to secure the proper tautness of bamboo paper. spray with an ordinary insect gun or ap-ply water with an ordinary brush. When applying with a brush be extremely careful so that you do not push the brush through the surface. After all parts have become thoroughly dry, apply coats of clear dope. Three coats shauld be enough with a light sanding between each coat..."
