< Back Replica De Havilland DH71 Tiger Moth Racer takes to the air 23 Dec 2024 Steve Jones’ replica DH71 Tiger Moth Racer made a highly successful maiden flight on 26th November, piloted by Steve himself. The immaculate monoplane, appropriately registered G-ECDX, is a full-size recreation of one of only two examples built by de Havilland in 1927. Of all wood construction, and fitted with a modified DH Gipsy 1 engine, the original DH71s were created to publicise their new Gipsy engine before releasing it onto the market to power their already successful DH60 Moth biplane. An exercise in light weight and streamlining to maximise speed, the DH71 was also significant in developing construction techniques that de Havilland used to good effect in later designs. The original DH71 achieved 186mph around a 65 mile closed circuit course, its Gipsy 1 engine souped-up from 85 to 130 horsepower for racing. The replica project was largely built by Ron Souch in the 1990s, under PFA supervision, using drawings produced by Ron’s friend Ben Price, a former aircraft draughtsman who put forward the idea as his retirement project. None of the original construction drawings had survived, so the design had to be recreated based on a three-view, photographs, press articles and intimate knowledge of de Havilland’s standard design techniques – and then checked against modern design code requirements. Most challenging part of the design were the details of the internally bungee-sprung wheels, as on the original. The project was paused for several years after issues came to light with the stressing of the wing spars and undercarriage. Steve Jones, looking for a hangar-mate for his scratch-built Comper Swift project, purchased the DH71 in 2016. Steve quickly got things moving again by commissioning re-designs of some of the original components, stripping off the fabric covering, re-sparring the wings and finishing the aircraft off to the same high standard as its original construction. The final examination of the assembled aircraft by LAA HQ’s design staff in November, when ground runs of the modified engine and its very coarse pitch Hercules propeller were demonstrated, took place over three decades after the project’s inception. When Steve’s replica DH71 first lifted off from Sywell’s grass runway, it was a sight not seen in Britain for 95 years. Big congratulations to all involved, especially to Ron and Ben for initiating it, and Steve’s perseverance and skill in finishing all the last details to such a high standard. Honourable mentions also to John Tempest for the re-design work and Ben Cox for inspecting it, this was truly a team effort. Sadly, Ron Souch is no longer with us to see the Racer fly. Steve describes his aircraft experience as starting as an aircraft engineering apprentice at CSE Kidlington, in the late 1970s. He towed gliders at Husbands Bosworth, in Chipmunks, at age 19, and joined the Tiger Club in the late 1970s, becoming a flying instructor at Staverton 1981. As he describes it, he somehow (?) ended up flying BA 747s for 20 plus years. His remarkable flying career has involved air racing, aerobatic competition and display flying, Redbull competitions and record setting in the Rolls Royce electric powered ‘Spirit of Innovation’ aircraft.

The course explains how to interpret a ‘typical’ permit aircraft electrical systems diagram and for every element, explains how to size, select and source components and then how to practically install them. This Advanced course builds on the Basics course by providing more detail about component selection and options and the use of integrated power management systems within permit aircraft. The course takes the simple systems design introduced in the Basics course and explores options for creating more complex electrical systems including the use of dual and essential system bus bars. The course introduces fault tolerant design considerations, thus allowing attendees to consider safety and fault analysis in their own designs. As a tool for understanding this aspect of the course, it will take an introductory look into the requirements of electrical systems for those wishing to fly their aircraft under IFR. What this course will try to do is: Explain power generation and distribution options in a light aircraft More advanced consisderations into component selection Discuss circuit protection devices and systems Explain failure modes and reliability issues Introduce interference and EMC issues Show correct grounding and screening techniques Provide you with the knowledge to plan an installation and create the necessary documentation Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you overnight into an expert Enable you to fault find on an undocumented aircraft installation Delve inside avionics boxes It will be useful, but not essential, for people to have previously attended the Basic course. In order to make the best of this course, if you have not attended the basics course, you will need to understand basic DC theory; Ohms Law and the Power Law. Please note that this course is primarily a classroom based course, as you will already have the practical skills you need, which are covered in the basics course.
