2025 Robinson R44 Raven IIPiston Helicopter • Stratford-on-Avon, England, UK

This 2025 Robinson R44 Raven II, offered for sale by HeliAir and located in Stratford Upon Avon, Warwickshire, United Kingdom, is a used example of the world's most popular four-seat helicopter. The Raven II derivative benefits from a fuel-injected, angle-valve, tuned-induction Lycoming IO-540 engine, which is de-rated to 245 HP for five minutes and 205 HP maximum continuous to extend longevity and reduce maintenance costs. This powertrain eliminates the need for carburettor heat, provides a favorable 100 lb increase in gross weight over earlier R44 models, and improves in-ground-effect and out-of-ground-effect hover ceilings.
