The giant scale DR-1 Triplane plan set is 1/4.4 scale and consists of three large sheets that clearly illustrate all structure. The DR-1 Triplane plan shows the installation of fixed wire gear, servos and Quadra 35 engine and features three, one piece wings. 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 don’t have the tools or time to cut your own kit Nick Ziroli Plans now carries laser cut wood kits for the DR-1 Triplane plan .The plans have instructions and building notes on the plans. If you choose an engine not shown on the plans you should have it on hand when you start construction to make any changes needed for mounting. Nick Ziroli Plans recommends covering the airframe with an iron on cloth covering such as Solartex. Nick Ziroli Plans has building and scale accessories available for the DR-1 Triplane.
