Sindlinger Super Pacer II

10/04/2004. Remarks by Fred Sindlinger: "The Super Pacer started out from a basket case 1953 Piper Tri-Pacer. The fuselage was modified by adding 16 inches to the frame just aft of the baggage compartment. Conversion to a tail wheel aircraft required a kit from Univair Aircraft. The rest of the fuselage was left original except for adding a few stringers to bring it into shape.

Vertical tail is original except that there is no off-set. The off-set was compensated for by mounting the engine with 2° down and 2.5°s to the right. Elevators were changed to accommodate an air balance tab to relieve some of the stick forces.

Wings are of my own design with a NACA 63A412 airfoil section. Wings are wood throughout, both spars and wing ribs. Dihedral is set at 2°. Flaps go from -3° negative to +45°. (-3,0,15,30,45 settings.) Ailerons can be drooped from the cockpit through an arrangement of pulleys to shorten and lengthen the control cables from -3° to +17°. (-3,0,10,17 settings.) The wings weight 200 lb (91 kg) due to using the original lift struts which put a greater bending moment on the spars at the lift attach points as there is an extra 2 1/2 feet of wing on each side. The front spar is 2 in (51 mm) thick at the attach point and the rear spar is 1.75 in (44 mm) thick."
