The giant scale Spirit of St. Louis plan set is 1/4 scale and consists of four large sheets that clearly illustrate all structure as well as showing installation of gear and wing struts. The Spirit of St. Louis plan shows the installation of Robart wing and gear struts, servos and Zenoah G-62 engine and features two piece wing. The basic structures use conventional “modeling” tools and materials such as balsa and plywood, and the techniques are straightforward; easily accomplished by anyone with previous model building experience. There are many online building threads at www.rcuniverse.com forums and www.rcscalebuilder.com forums for Nick’s plans. Tech support is also available via email at www.ziroliplans.com or by phone 9:00 to 5:00 Mon - Fri EST 631-467-4765. The plan includes full-size templates for all the required parts allowing you to cut a complete “kit” before you start construction. If you would like to purchase a wood kit see KIT CUTTER'S on selection bar at the top of each page. If you choose gear or an engine not shown on the plans you should have them on hand when you start construction to make any changes needed for mounting. Nick Ziroli Plans recommends covering the airframe with cloth such as Sits system or Solartex. Nick Ziroli Plans has building and scale accessories available for the Spirit of St. Louis.
