Welcome! I am offering a vintage Sterling WACO S.R.E. remote control balsa airplane model kit. This kit has a finished wingspan of 56 1/2 and will require a .40 to .60 engine. This kit is complete and unstarted. The plans and decals are nice. All balsa pieces are still on their sheets. All plastic parts (cowl & wheel pants) are perfect. The scale is 1 5/8=1ft. The box is in nice condition except for lots of tape. This kit has been out of production for many years, and is becoming harder to find. Shipping will be by USPS Parcel Post (wrapped in heavy brown paper) or USPS Priority Mail (in a box), with delivery confirmation.
