Aircraft kit-building has seen a phase of strong growth in the last 10 to 15 years, especially when it comes to the quality of kits. With the proliferation of computer-aided design providing the ability to do a range of tasks from the machining of moulds for accurate composite parts, to the CNC-controlled cutting and drilling of metal components, homebuilders can now buy kits that build with much less frustration than in the past.
In the UK, the amateur building of homebuilt light aircraft is overseen by the Light Aircraft Association (LAA), which operate under a delegated responsibility from the Civil Aviation Authority. There are around 200 approved designs you can choose from, though most new builders choose from around 30 of those, as they are the most current, supported types.
Ed Hicks of Flyer Magazine in the UK reviews four types, one of which is, of course, the Sling TSi.
