I received the Topflite Super Decathlon kit from Tower Hobbies on 29 February 2012 and have been working steadily on it ever since. The build is going along great with lots of help from the contributors on this thread. The engine is OS 120AX. Things on the to-do list include: Install aileron control rods and extension cable; Fiberglass tape the struts, wheelpants, ABS cowl and paint them; Paint cabin area and cover the fuselage; Add trim color pattern; Install windshield; Replace tail wheel with Ohio assembly on-hand; Reinforce landing gear with music wire on-hand; Install flying wires; Install receiver and battery; then the finishing details like weight and balancing, setting the control throws, etc. Thanks to all the contributors on this thread as their guidance has been invaluable.
