The Ercoupe is a low wing monoplane first manufactured shortly before WWII. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type still enjoys a very faithful following today.


The giant scale Ercoupe plan set is 1/4.5 scale and consists of three large sheets that clearly illustrate all structure as well as showing installation of gear struts. The Ercoupe plan shows the installation of Robart gear struts, servos and Zenoah G-23 engine and features three 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. The plans have a separate instruction guide and building notes on the plans. 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 fuselage with 1 oz fiberglass cloth and ZAP Z-poxy finishing resin and the wings ,elevator and rudder with iron on cloth covering such as Solartex. Nick Ziroli Plans has building and scale accessories available for the Ercoupe.
