Over many years as an affordable aviation journalist I have learned two things. First, stick to airplanes. That’s what moves the needle for most pilots; nearly always such articles are the best-read on this website. Second, pilots love more powerful engines, especially when they display new technologies. Speedy LSA maker, JMB Aircraft has tapped into this rich vein of interest. For some years, they have worked to make their elegant and shapely VL3 go faster than before (earlier evaluation article). A year ago at Sun ‘n Fun, the Belgium-headquartered company showed Americans their 141-horsepower Rotax 915iS model. The machine looked quick merely sitting in their display. That wasn’t enough. Even though JMB can max out at 230 mph now, leaders and engineers at JMB thought, “Why not try a turboprop?” JMB Turbine Not even a month ago, this leading builder of LSA speedsters took their turbine-powered VL3 into the air for the first time, in France on Monday April 4th, 2022.

JMB Turbine
Not even a month ago, this leading builder of LSA speedsters took their turbine-powered VL3 into the air for the first time, in France on Monday April 4th, 2022. Later that month, the company debuted the development to crowds at Aero Friedrichshafen 2022.TURBINE POWER — TurboTech's heat-exchanger turbine engine is being used on three LSA designs.
Longer Life / Cheaper Fuel
Proponents of TurboTech's method say it is superior due to its longer time before overhaul (TBO).WIDER USES — TurboTech also envisions their turbine as a generator for hybrid-electric propulsion.
FAA's Mosaic & Turbines?
The short answer about turbines being permitted: We don't know today but we might find out at Oshkosh 2022 when I expect FAA will release the draft regulation as a Notice of Proposed Rule Making (NPRM).LONG & LEAN — JMB Aircraft's installation of the TP-R90 turbine into their VL3 model. photo by John Rathmell
