The Cessna 170 is a light, single-engine, general aviation aircraft produced by the Cessna Aircraft Company between 1948 and 1956. The Cessna 170B was introduced in 1952 featuring a new wing tapered outboard of the flaps, incorporating dihedral similar to the military version. The B model was equipped with very effective modified-Fowler (slotted, rearward-traveling) wing flaps which deflect up to 40° adapted from the C-305/Bird Dog, a wing design that lives on in the Cessna light singles of today (constant NACA 2412 section with a chord of 64 inches (1,600 mm) from centerline to 100 inches (2,500 mm) (the outboard end of the flaps), then tapering to 44-inch (1,100 mm) NACA 2412 section chord at 208 inches from centerline, with three-degree washout across the tapered section). The 170B model also included a new tailplane, a revised tailwheel bracket, and other refinements over the 170 and 170A. (photo of original for comparison)
