The Cicaré CH-7 is a helicopter made by the Argentine manufacturer Cicaré Helicópteros .
History and construction
After developing the CH-5, Augusto Cicaré turned to a new project, the CH-7, which emerged from the CH-6 test platform. The CH-7 consists of the tubular steel frame with the engine of the CH-6, on which a single-seat cabin was attached. The helicopter is powered by a Rotax 582 two - cylinder two-stroke engine with 48 kW and has a main rotor and a cabin made of composite material, as well as several mechanical improvements. The first flight took place in 1991. The machine was then presented at various aviation trade fairs and was to be marketed as a kit. Due to the significantly higher price compared to other helicopter kits at that time, only one order was placed. However, the design met with great interest in Europe, so that Heli-Sport acquired the production rights and launched the first helicopter, after the cabin was redesigned, under the name Heli-Sport CH-7 Angel . This was followed by a whole series of further developments through Heli-Sport. Outwardly, the helicopters from Cicaré and Heli-Sport are similar, but differ mainly in the cabin design. Because while at Cicaré you have to enter the cabin from the side, Heli-Sport chose the way that the entire upper part of the cabin can be pushed forward and tilted. In addition, the two models differ, with the exception of the CH-7 Angel , which was initially sold together and is therefore sometimes referred to as the Cicaré CH-7 Angel , by the tail boom modeled on the Revolution Mini-500 .
After a few years, Augusto Cicaré began further developing the CH-7 himself, and in 2009 he produced the CH-7B . This is driven by a Rotax 912 ULS four-cylinder four-stroke boxer engine with 73.5 kW. There were also some minor technical changes and the cabin was also revised. This helicopter is also offered as a kit and can also be used in agriculture with appropriate equipment for spraying (also known as CH-7Bt).
Using the more powerful Rotax 912 resulted in an immediate increase in performance, which made the model more interesting for potential buyers. A side effect of the higher performance was that considerations were now taking place to develop a two-seater model, which led to the CH-7T in 2014 . Here the pilot and passenger sit close to one another. For the European market, the CH-7T was named Spirit . The CH-7T is also used in agriculture.
In order to increase the use of helicopters in the private sector , two Rotax engines (presumably Rotax-582 ) were installed in a CH-7, which was now called the CH-7 2000VL , in 1996 , whereby the helicopter was only safe with one could land.
Over the years, the CH-7 models from Cicaré and Heli-Sport have become the most popular in the sports helicopter scene, also due to the low price, so that a plant has been built in San Sebastian in the Basque Country for several years , in which about two Helicopters are assembled per month.
