The giant scale AD-1 Skyraider plan set is 1/6 scale and consists of four large sheets that clearly illustrate all structure as well as showing installation of flaps and retracts. The AD-1 Skyraider plan shows the installation of Robart retracts, fixed wire gear, servos and Zenoah G-62 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 plan 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 1 oz fiberglass cloth and ZAP Z-poxy finishing resin. . Nick Ziroli Plans has building and scale accessories available for the AD-1 Skyraider.
