The fuselage and wings of this model were purchased in the auction at the 2013 Denton Swap Meet. They were completed and covered with the red base Monokote; however, the wing structs, plans, miscellaneous parts were missing. A few months later a badly worn copy of the plans were found that enabled construction of the wing struts and finishing/equiping details. Acquired an older model OS-120 (NIB) at the February 2014 Georgetown Swap Meet, which was perfect for this model weight and balance and power wise. This model is easy to fly and is somewhat forgiving. I did add wing tip skids to protect the wings during my wobbly landings.
