Bell 407 has a four-bladed bearing rotor designed for OH58D (Model406). Sleeve and blades without assigned resource are made of composite material and provide the best in comparison with previous models comfort and other flight characteristics. Vibration-isolating means are used in the design of the main-rotor pylon; similar means are introduced into the skid landing gear scheme to eliminate the resonance near the ground. Compared to the Bell 206, the 407 fuselage is wider by 18 centimeters, which increases the cabin volume. Glazing area is larger by 35 percent. The helicopter is equipped with a Rolls Royce / Allison 250 C47 turboshaft engine: take-off power 813l.s. (606kW.), The longest continuous power of 700l.s. (522kW.).

The engine is equipped with a single-channel FADEC type electronic control system. Common stock 477l fuel; in the luggage compartment rear optional extra tank can be placed with a capacity 75l. The engine provides the greatest improvement in take-off weight and the properties at high altitudes and at high temperatures. Glider 407 generally similar in appearance to LongRanger, but it differs from the tail boom, and which is made of carbon fiber. In a typical configuration, the helicopter room for five passengers and two crew members.

Bell in the 1995 year tested the tail rotor, which is enclosed in a ring, but this idea was later abandoned. Bell engineers also investigated the possibility of installing two engines on the Bell 407, but instead decided to design a completely new twin-engine helicopter called the Bell 27. He received as the power plant two PW206D Pratt & WhitneyCanada engines.

The Bell 407 helicopter brought great popularity around the world record flight, its route passed through the North and South Poles of the Earth. A car with two crew members on board took off from the airport of Fort Worth (Texas) 5.12.2006 of the year and returned back to 23.03.2007 of the year. Over 189 days, more than 57900 km was overcome, a couple of dozen landings were made, even at the North and South Poles. Net flight time was 300 hours.
