This plan requires that the builder has scratch building experience

The giant scale B-25 Mitchell plan set is 1/7 scale and consists of four large sheets that clearly illustrate all structure as well as showing installation of flaps. The B-25 Mitchell plan 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 Scratch 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. The 118” B-25 Mitchell uses gear and engines 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 1 oz fiberglass cloth and ZAP Z-poxy finishing resin and elevator and rudders with cloth covering such as Solartex. Nick Ziroli Plans has building and scale accessories available for the B-25 Mitchell.
