Mid wing placement — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/mid-wing/ (sheet CC BY 4.0; files Xem Studio Design License, https://xemstudio.com/license/) Basis: Design rules and figures from the cited sources; example geometry by Xem Studio Catalog version: 2026-10-20 Sizes: see table below - A mid wing meets the fuselage at right angles, which wind-tunnel reports favoured for low interference drag (US Naval Institute, Corsair design history). - With ailerons, McCombs recommends 'essentially 0 deg' effective dihedral for mid-wing and biplane RC models, and 7-8 deg for rudder-only mid-wing models (Model Aviation). That near-neutral roll response suits aerobatic aircraft (Kitplanes). - A mid wing's spar crosses the fuselage, which can be awkward; the Corsair's designers avoided a long, heavy landing gear by bending the wing instead (USNI). - The file is a reference example built by Xem Studio from the numbers above. Sizes the sources do not fix are illustrative; scale the example to your own vehicle. parameter value or range source RC with ailerons, mid wing essentially 0 deg McCombs 1994 RC rudder-only, mid wing about 7-8 deg McCombs 1994 FF scale, mid wing EVD 0-5 deg McCombs 1994 Reference build 1000 x 200 mm, 0 deg dihedral McCombs Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - US Naval Institute, Naval History Magazine: Designing the Bent-Wing Bird (Feb 1995) — web — Publisher's page; dimensions are facts — https://www.usni.org/magazines/naval-history-magazine/1995/february/designing-bent-wing-bird - Model Aviation (AMA), W.F.
