Model TSC-1A2 "Teal II" amphibian has been
developed from Model TSC-1A1 through addition of slotted flaps (116 in
each) and from aerodynamical refinement realized by increasing the
stabilizer negative incidence from -3° to -5°. No increase in
the wing control surface or tab areas was considered necessary -
although the elevator trim tab deflections were increased.
Flight test evaluation confirmed an anticipated
reduction in stalling speed, permitting operation from water at higher
gross weights (2 200 lbs) while maintaining acceptable structural
margins. The application of slotted flaps deflected 15° actually
reduced both take off run and take off time at 2 200 pounds gross,
compared to former unflapped operation off water at 2 100 lbs for Model
TSC-1A1.
