The Pro-Composites Freedom is an American amateur-built aircraft, under development by Pro-Composites of Buffalo Grove, Illinois. The aircraft is intended to be supplied in the form of plans for amateur construction, with some pre-formed parts made available to speed construction.Bayerl, Robby; Martin Berkemeier; et al: World Directory of Leisure Aviation 2011-12, page 115. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X{{cite web|url = http://pro-composites.com/Freedom%20Info.html|title = Freedom|accessdate = 14 October 2012|last = Pro-Composites|date = n.d.}}
Design and development
The aircraft features a cantilever low-wing, a four-seat enclosed cabin accessed by doors, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.
The aircraft is made from pre-formed flat fiberglass and foam composite panels which are then radius bent to shape. Its {{convert|30|ft|m|1|abbr=on}} span wing employs a NACA 63A-214 airfoil at the wing root, transitioning to a NACA 63A-212 airfoil at the wing tip. The wing has an area of {{convert|134|sqft|m2|abbr=on}} and the cabin will be {{convert|46|in|cm|0|abbr=on}} in width. The landing gear features a fully castering nosewheel and differential braking for steering. The aircraft has been designed for engines of {{convert|180|to|320|hp|kW|0|abbr=on}}.{{cite web|url = http://pro-composites.com/specs.html|title = Specifications|accessdate = 14 October 2012|last = Pro-Composites|date = n.d.}}
The manufacturer markets the design as "the only composite, plans built, 4 seat aircraft that uses a conventional - non canard - platform. It can be constructed entirely from the manuals using raw materials or from pre-formed parts."
