Vertipedia is a product of the Vertical Flight Society. With data on 859 aircraft, 612 historical milestones, 472 people, and 392 organizations, Vertipedia is your "one-stop shop" for all things vertical lift.
Our latest featured aircraft for August is the Cierva W.11 Air Horse .
The aircraft was designed to provide viable heavy load lifting capability for commercial operations. It employed 3 main rotors all rotating in the same direction. Torque offset was provided by thrust components from the 3 rotors through built-in shaft tilt. The aircraft had a semi-monoquoque structure, a single engine, and a long-stroke undercarriage (5ft) to cope with high rates of descent. A description of the aircraft and its characteristics can be found in the following references,

Why not use just typical data for a Type of aircraft?
Other databases (e.g. Wikipedia) tend to show typical data for one aircraft deemed to be representative of a Type. Whilst this can be informative, it implies that all other aircraft are very similar, which may or may not be true. Vertpedia allows users to enter data for any aircraft in a Type series. This is particularly useful when there are significant, or noteworthy, differences between individual aircraft within the Type and avoids someone having to decide what is representative.
