Bjorne Andreason's airplanes all seem to look right and fly right also. The author flew the original BA-7 in California when it was first built, so when the three view of the BA-4B was published in the Experimental Aircraft Association's journal, 'Sport Aviation' he just had to build a model of it. Peanut Scale, with a limit of 13 inches maximum span has lots of appeal so the BA-4B model was designed to be a 'Peanut Scale'. As a flying model it turned out really fine and flew right off the board. Early flights with a twelve inch loop of one eighth flat Pirelli were between thirty and forty seconds with the landing under power. Later flights, outdoors, with a shorter motor and more climb disclosed a slight lack of vertical tail area which caused the model to spiral down to the right in the glide if it was adjusted to fly w ell under high power. A clear plastic tail extension was added to the model and it flies and glides well. This extension is indicated on the plans and perhaps can be discerned in the photos.
