Model TSC-1A2 Teal II Specifications

Home | TSC-1A | TSC-1A1 | TSC-1A2 | TSC-1A3

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.
