# HQ Aviation: Full Reference > HQ Aviation is the UK's premier Robinson Helicopter dealer, offering flight training, new and pre-owned aircraft sales, CAA Part-145 maintenance, self-fly hire and worldwide expeditions from Denham Aerodrome, around 30 minutes from central London. This document expands on the curated guide at https://hqaviation.com/llms.txt with fuller descriptions of each area of the HQ Aviation website. Every fact below is drawn from the company's own site content. Indicative prices are marked as such and may change; the live machine-readable index of all pages, including current pre-owned aircraft listings and store products, is at https://hqaviation.com/sitemap.xml. ## Company Overview HQ Aviation Ltd was founded by Captain Quentin "Q" Smith at Denham Aerodrome, just outside London, and has grown into the UK's leading Robinson helicopter specialist across training, sales, maintenance and expeditions. The company presents itself as a Robinson Authorised Dealer and Service Centre, a CAA Part-FCL Approved Training Organisation (ATO), and an EASA and CAA Part-145 approved maintenance facility, selling factory-new R22, R44 and R66 helicopters direct from the Robinson Helicopter Company in Torrance, California. It also holds Guimbal Cabri G2 service-centre approval and uses factory-trained technicians and genuine Robinson parts. Headline figures quoted across the site include more than 35 years of operation, 500 or more pilots trained, over 30,000 flight hours, and activity across seven continents. The culture is described as a clubhouse rather than a flight school, with on-site engineering, seven-day operations and a community of pilots, engineers and adventurers. Denham Aerodrome sits just inside the M25, roughly 25 to 30 minutes from central London, and was established in 1934. Key facts: - Legal name: HQ Aviation Ltd.

He holds an Air Transport Pilot Licence (Helicopters) and is both a helicopter instructor and examiner. He is a two-time Helicopter Aerobatics Freestyle World Champion, winning gold in Moscow in 1994 (the first British pilot to do so, flying a Robinson R22) and again in 2012, and he holds the FAI Gold Rotorcraft Medal, presented at the FAI's 2020 awards ceremony. His record-breaking expeditions include the 1997 round-the-world flight with Jennifer Murray in Robinson R44 G-MURY (97 days, 28 countries, now held by the Smithsonian), the first piston-powered helicopter landing at the North Pole in 2002 (a Guinness World Record), and landing an R44 at the South Pole in 2005. When Paramount Pictures needed someone to teach Tom Cruise to fly a helicopter for Mission: Impossible Fallout, they came to Captain Q, whose training compressed roughly 2,000 hours of experience into about three months ahead of the 2018 film. ## Flight Training HQ Aviation trains pilots on the Robinson fleet from Denham as a CAA Part-FCL Approved Training Organisation, from a first hands-on flight through to a commercial licence and advanced post-licence work. ### Trial Lessons and Discovery Flights https://hqaviation.com/training/trial-lessons A first hands-on helicopter flight at Denham, offered in the Robinson R22, R44 or R66 over the Chiltern Hills, as a one-off experience or a first flight lesson. Each aircraft can be booked for 30 or 60 minutes, and gift vouchers are available. Indicative "from" prices in the booking system are R22 from £180 (30 minutes) or £360 (60 minutes), R44 from £305 or £605, and R66 from £315 or £635; live prices are managed in the site's pricing system and may differ. The instructor team includes founder Quentin Smith, Chief Flight Instructor Mackie Alcantara, George Agnelli and Phil Summers. ### PPL(H) Private Pilot Licence https://hqaviation.com/training/ppl Training for the helicopter Private Pilot Licence on the Robinson fleet (R22, R44 and R66). The course requires a minimum of 45 hours of flight training including at least 10 hours solo, typically falling in the 45 to 55 hour range depending on the student. Ground school covers nine subjects (Air Law, Navigation, Meteorology, Human Performance, Principles of Flight, Operations, Performance, Communications and Aircraft Knowledge), examined by multiple-choice tests on site as an approved CAA test centre, taken in any order at the student's pace, each requiring a 75 percent pass mark. Only the Air Law exam is needed before going solo, and ground school is included. ### CPL(H) Commercial Pilot Licence https://hqaviation.com/training/commercial The modular route from a PPL to a professional helicopter licence. The pathway runs from the 45-hour PPL through 110 or more hours of hour building to reach 155 total hours including 50 as pilot-in-command, the nine ATPL(H) theoretical-knowledge exams at an approved centre, 15 or more hours of focused CPL flight training, and a one-day CAA skill test. The process typically takes 18 to 24 months depending on starting hours. The licence opens routes into charter and air taxi, tours and sightseeing, aerial survey and photography, flight instruction (with an added FI(H) rating), emergency services such as police, coastguard and HEMS, and corporate aviation. ### Helicopter Type Ratings https://hqaviation.com/training/type-rating For existing PPL(H) holders adding a new helicopter type. A type-specific ground course is followed by a minimum of five hours of flight training before the type-rating test, with a typical duration of 3 to 5 days (ground school 1 to 2 days, flight training of five or more hours, a skill test of 1 to 2 hours with a CAA examiner, then same-day certification). Aircraft shown on the page include the Robinson R22, R44 and R66, the Hughes 500, the AS350 Squirrel and the Bell 407; the page's SEO copy also lists Airbus AS350 and EC130 ratings. Prerequisites are a valid PPL(H) or higher, a valid Class 2 or LAPL medical, a pilot logbook, and passport or ID. ### Helicopter Night Rating https://hqaviation.com/training/night-rating An additional qualification that lets PPL(H) holders fly during the hours of darkness, removing the day-only restriction. Training is five hours of dual instruction flown in a Robinson R44 or R66 at Denham. Prerequisites are a valid PPL(H), a minimum of 100 hours total flight time, 60 hours as pilot-in-command, and a valid Class 2 or LAPL medical. The course runs through ground school, dual night circuits and night-navigation cross-country flying, then a skills test with a CAA examiner, and is typically scheduled in winter months. ### Advanced Helicopter Training https://hqaviation.com/training/advanced Post-licence skill development built around four specialisms: autorotations, confined areas, mountain flying and safety courses. It is led by Captain Quentin Smith and covers emergency scenarios that initial licence training does not, including full autorotations, tail-rotor failures, vortex-ring recovery, engine-failure drills, pinnacle and slope landings, and over-water operations. The autorotation clinic is open to PPL(H) holders from 50 hours; mountain and confined-area work suit pilots with 100 or more hours. All courses use HQ's own aircraft, with mountain flying run as day trips to suitable UK terrain. ## Aircraft Models HQ Aviation sells the new Robinson range and supports several other types. Performance figures below are taken from the site; new-aircraft prices are indicative factory list prices in US dollars (Robinson list effective 1 January 2026) and are shown live in pounds on the sales pages. ### Robinson R22 Beta II https://hqaviation.com/aircraft/r22 A two-seat Lycoming O-360 piston trainer, described as the world's most popular training helicopter and the most affordable route into rotary flight. Its direct push-rod controls give unfiltered feedback that transfers to heavier types. Indicative factory list price around 375,000 US dollars. Performance: 2 seats, Lycoming O-360-J2A (145 HP continuous), cruise 96 kts, VNE 102 kts, range about 200 nm, maximum take-off weight 1,370 lb, 2,200-hour TBO. The type entered production in 1979, the Beta II arrived in 1996, and more than 4,800 have been delivered. Captain Quentin Smith won the 2012 World Helicopter Aerobatic Championship flying an R22. ### Robinson R44 https://hqaviation.com/aircraft/r44 Robinson's four-seat piston family, the most-built civilian helicopter in history and the number-one general aviation helicopter every year since 1999, with more than 6,500 built since first certification in 1992. The Raven I uses a carburetted Lycoming O-540; the Raven II a fuel-injected Lycoming IO-540 (245 HP continuous) with higher cruise and better hot-and-high performance; the two-seat Cadet is a derated trainer. Indicative factory list prices: Cadet around 520,000, Raven I around 553,500 and Raven II around 646,000 US dollars. Performance (Raven II): cruise about 117 kts, range about 400 nm, useful load about 900 lb, VNE 130 kts, rotor diameter 33 ft, engine TBO 2,200 hours or 12 years. The R44 was the first piston helicopter to reach both the North Pole (2002) and South Pole (2005). ### Robinson R66 Turbine https://hqaviation.com/aircraft/r66 Robinson's first turbine helicopter, a five-seat machine powered by a single Rolls-Royce RR300 turbine, with the largest cabin in the Robinson lineup and operating costs below other turbines. Performance: 270 shaft horsepower, maximum speed 140 kts, cruise about 110 kts, useful load about 1,200 lb, rotor diameter 33 ft, range from 350 nm on standard fuel up to around 550 nm with the auxiliary tank, 2,000-hour engine TBO. The NxG trim range runs from the Southwood (indicative list around 1,456,000 US dollars) through the Palo Verde to the limited Riviera (around 1,777,500 US dollars), with a four-seat NxG Police build available. Avionics include the Garmin G500H glass cockpit and GFC 600H autopilot. ### Robinson R88 https://hqaviation.com/aircraft/r88 Robinson's forthcoming utility turbine, its first all-new clean-sheet helicopter in 15 years since the R66, currently pre-production and not yet shipping. HQ Aviation, a UK Robinson dealer, takes R88 pre-orders with deposits ahead of production, and provides information, updates and consultation for UK and European operators. It is a dual-pilot machine seating ten in total (an eight-passenger cabin), powered by a Safran Arriel 2W in the 950 shaft-horsepower class, with range of 350 or more nm, endurance of 3.5 or more hours, a cabin of about 275 cubic feet and an internal payload of 2,800 lb. The starting price is a pre-production estimate of 3.3 million US dollars. The R88 was announced in March 2025 at Verticon and had secured more than 150 orders worldwide. ### Hughes and MD 500 https://hqaviation.com/aircraft/h500 A reference and heritage page for the Hughes and MD Helicopters 500 series, an iconic light turbine helicopter that HQ Aviation maintains and supports rather than sells new. Performance: Rolls-Royce 250-C20B/R turbine (420 to 450 SHP), maximum speed 152 kts, cruise 135 kts, range 235 nm, service ceiling 16,000 ft, five seats, a five-blade main rotor and a 3,000 lb maximum gross weight. The lineage runs from the 1963 first flight of the Hughes Model 369 (the military OH-6 Cayuse), the civilian Hughes 500 of 1966 to 1967, the 500D of 1976 and the McDonnell Douglas acquisition in 1984. ## Buying and Selling Aircraft ### New Robinson Helicopters https://hqaviation.com/sales/new HQ Aviation's new-aircraft sales page presents the full Robinson lineup to order: the two-seat R22 Beta II, the four-seat R44 (Cadet, Raven I and Raven II), the five-seat R66 Turbine (Southwood, Palo Verde and Riviera NxG editions) and the new R88 turbine flagship with up to ten seats. A guided six-step buying process runs through consultation, configuration (model, options and livery), factory order, production at Robinson's Torrance facility, delivery (factory-direct or assembled at HQ Aviation) and handover with ongoing support. An interactive lineup shows a live "from" price per variant in pounds with approximate US dollar and euro equivalents, alongside an aircraft comparison tool. Enquiries reach sales@hqaviation.com or +44 1895 833373. ### Pre-Owned Helicopters https://hqaviation.com/sales/pre-owned Used Robinson R22, R44 and R66 helicopters, with current listings loaded live from the site's content system. Each card shows model, price, year, registration and total airframe hours, carries a Reserved badge where applicable, and links to a detail page at /sales/pre-owned/. Every aircraft is inspected at HQ's CAA Part-145 facility before it is listed, and a Recently Sold section shows previously sold stock. ### Robinson Rebuilds and Overhauls https://hqaviation.com/sales/rebuilds A full Robinson rebuild built to the customer's specification at HQ's CAA Part-145 facility, returning the aircraft to factory-new, zero-time condition with customised avionics, interior, paint and equipment at a saving over a new factory aircraft. The page covers the R22 Beta II, R44 Raven II and R66 Turbine, with indicative rebuild prices plus a separate donor-airframe cost range for each. The six-step process runs through consultation, donor sourcing, strip and inspect, rebuild, test and certify, and handover with documentation, warranty and support. ### We Buy Any Robinson https://hqaviation.com/we-buy-any-robinson An acquisition service: HQ Aviation will buy any Robinson R22, R44 or R66, of any year and any hours. The core argument is the overhaul rule (every Robinson reaches overhaul at 12 calendar years or its hour limit, whichever comes first; the limits are 2,200 hours for the R22 and R44 and 2,000 for the R66). A low-utilisation private aircraft times out on the calendar with hundreds of hours unflown, and because HQ's own training fleet flies daily it can use those remaining hours and price them into its offer. Selling runs in four steps: tell us about it, get a fair-market valuation within 48 hours, inspection at Denham by HQ's engineers, and payment on completion. HQ will also value other rotary types such as Cabri and Bell. ### Our Fleet https://hqaviation.com/fleet HQ Aviation's collection of helicopters operated from Denham for training and self-fly hire. The fleet detailed on the page covers the Robinson R66 Turbine (5 seats, Rolls-Royce RR300, 300 SHP), the Robinson R44 Raven II (4 seats, Lycoming IO-540, 260 HP), the Robinson R22 Beta II (2 seats, Lycoming O-360, 180 HP) and the turbine MD 500 series (5 seats, Rolls-Royce 250-C20B, 420 SHP), each with full specifications and registrations. HQ has operated Robinson helicopters since 2010 and is an Authorised Robinson Dealer, Factory Authorised Service Centre, CAA Approved Training Organisation and Robinson Safety Course provider. A "Book a Taster" prompt offers a 30-minute taster flight in the aircraft of your choice. For self-fly hire rates, see the Self-Fly Hire page. ## Ownership, Maintenance and Parts ### Helicopter Maintenance https://hqaviation.com/maintenance A Robinson Authorised Service Centre at Denham carrying out CAA Part-145 scheduled and unscheduled maintenance across the Robinson range (R22, R44 and R66) including the Rolls-Royce RR300 turbine. Engineers are factory-trained and current with the latest Robinson service bulletins and airworthiness directives. Services span scheduled inspections (50-hour, 100-hour and annual), engine and component overhauls, avionics installation and panel upgrades, pre-purchase inspections, paint and refurbishment, and 24/7 Aircraft on Ground (AOG) response across Europe. The facility runs up to eight service bays for fast turnaround, holds a genuine Robinson parts inventory valued at over 500,000 pounds with same-day dispatch for AOG, and carries out the major 12-year or 2,200-hour Robinson overhaul. Maintenance enquiries reach maintenance@hqaviation.com or +44 1895 832833. ### Self-Fly Hire https://hqaviation.com/self-fly-hire Solo hire of an HQ Aviation Robinson helicopter from Denham for qualified pilots, with no instructor and no fixed itinerary. The fleet covers the two-seat R22 (cruise 96 kts, range 190 nm), the four-seat R44 (cruise 109 kts, range 300 nm, UK and Europe capable) and the five-seat R66 turbine (cruise 120 kts, range 350 nm, Garmin G500H avionics). Requirements are a current PPL(H) with a valid Class 2 medical, a current type rating for the aircraft, recent currency (a checkout flight is offered if not current), and third-party liability insurance, which is included in the hire rate. Indicative wet rates are R22 £375, R44 £495 and R66 £595 per hour (excluding VAT), with live pricing pulled from the booking system. Flexible options include off-peak "Happy Hour" rates, ferry and repositioning "Mission" rates, and bulk-hour discounts. ### Leaseback Programme https://hqaviation.com/leaseback An owner programme: place your helicopter into HQ's operation, it flies on training and self-fly hire work, and you receive a share of the revenue while the aircraft remains yours. HQ handles maintenance, scheduling, pilot management and operational compliance, the owner keeps priority personal use, and monthly statements show flight hours, revenue and aircraft status. The process runs through an aircraft assessment, an operating agreement (revenue split, scheduling and insurance terms in writing) and ongoing operation. Eligible aircraft are the Robinson R44, Robinson R66 and Hughes 500. ### Leaseback Calculator https://hqaviation.com/leaseback/calculator A free interactive UK economics tool that models how much of a Robinson's airframe life an owner would leave unused, and what HQ would pay to fly the spare hours. It centres on the overhaul limits (an R44 at 2,200 hours or 12 years, an R66 at 2,000 hours or 12 years, whichever comes first), and owners adjust inputs for hours flown, aircraft age, personal flying and the per-hour rate HQ pays. The methodology draws on Robinson factory documents, real Denham hire and utilisation rates, and UK insurance and hangarage figures (with the commercial-use uplift, typically around double private cover, shown explicitly). Figures are illustrative not advice, ex VAT, and last verified June 2026; no email is required to use the calculator. ### Pilot Provisioning https://hqaviation.com/pilot-provisioning Fully rated, insured and briefed helicopter pilots supplied for owner-operators and yacht operators. Three services are offered: Safety Pilots (an experienced instructor as an extra layer of oversight, holding a current FI(H) rating, at least 500 hours total time, a type rating on the owner's aircraft and full insurance), Ferry Flights (moving aircraft for maintenance, delivery or repositioning, with fuel planning, weather routing, permits and logistics handled), and Dedicated Crewing (a contract crew member for ongoing operations such as seasonal superyacht programmes or filming contracts). The pilot team holds type ratings across the Robinson R22, R44 and R66, plus the Hughes 500, AS350 Squirrel, EC130 and Bell 407. ### Aircraft Consulting https://hqaviation.com/aircraft-consulting Independent, Robinson-specialist advice across the ownership lifecycle, grounded in around 35 years of experience and more than 500 transactions. Buying services include a Robinson-only Pre-Purchase Inspection (a full airframe, engine, avionics and logbook inspection with a written buy, renegotiate or walk verdict within 48 hours), Acquisition Advisory and independent Valuation and Appraisal. Owning and operating services include aircraft management, operating-cost and total-cost-of-ownership modelling, insurance advisory, and import, export and register transfers across the UK CAA, FAA, Isle of Man and Guernsey. Independent expert work includes formal CPR Part 35 expert reports and single joint expert appointments. Pre-purchase inspections are typically arranged within 3 to 5 working days. ### Parts Catalogue https://hqaviation.com/parts A searchable Robinson parts catalogue, with HQ presented as one of the biggest Robinson service centres in Europe with direct relations with the Robinson factory. Inventory spans engine components, airframe parts, consumables, avionics and accessories, filterable by category (rotor, engine, avionics, consumables, airframe, hardware), by aircraft (R22, R44, R66) and by condition, with free-text search across part number, title, description, category and compatibility. Each part links to its own detail page showing price (or POA) and stock. A bespoke sourcing service answers enquiries by part number or description within 24 hours, and the page cross-links to HQ's Easy Wheels, Start Stick and Aircraft Covers products. ## Experiences and Specialist Operations ### Worldwide Expeditions https://hqaviation.com/expeditions Multi-day, pilot-led helicopter expeditions where participants take the controls themselves, aimed at licensed pilots and aspiring aviators.
