The first helicopter produced in Vietnam was the V-24, which was developed in the early 1980s by the Vietnam Helicopter Corporation. The prototype was completed in 1984, marking a significant milestone in Vietnam's aviation industry, as it was the country's first domestically manufactured helicopter.

To take off in a helicopter, the pilot first ensures that all systems are operational and conducts a pre-flight check. The collective pitch control is gradually pulled up to increase the rotor blade angle, generating lift. As the helicopter rises, the pilot uses the cyclic control to maintain stability and direction. Once a safe altitude is reached, the pilot can transition to forward flight.

The capacity of a tourist helicopter typically ranges from 4 to 6 passengers, depending on the model and configuration. Some larger helicopters can accommodate up to 10 or more people, including the pilot. It's essential to consider weight limits and safety regulations, which can also affect the number of passengers allowed. Always check with the specific tour operator for their helicopter's capacity and guidelines.

A Chinook helicopter, specifically the CH-47 Chinook model, has a maximum speed of approximately 196 knots, which is around 226 miles per hour (364 kilometers per hour). Its cruising speed is typically around 150 knots (173 miles per hour or 278 kilometers per hour). This speed, combined with its heavy lift capability, makes the Chinook an effective transport helicopter for military and logistical operations.

The passenger capacity of a helicopter varies depending on its model and design. Typically, small helicopters can accommodate 2 to 6 passengers, while larger models, such as those used for commercial air tours or medical transport, may carry up to 15 or more passengers. For example, popular helicopters like the Bell 206 can seat up to 4 passengers, while larger ones like the Sikorsky S-76 can transport up to 12. Always check specific aircraft specifications for accurate capacity information.

The first remote-controlled helicopter is credited to the American inventor John C. F. H. McCulloch, who created a model in the 1930s.
