Very low-power engines have been built that run on a temperature difference of as little as 0.5 K.

The combination of the low-performance 1-19 and the low-power engine left the aircraft unable to climb out of ground effect.

The Q1W carried two low-power engines, allowing for long periods of low-speed flight, and was the first purpose-designed anti-submarine warfare aircraft in the world.

The old designers, working with low-power engines and the heavy loads imposed by the uncontrolled landings of free-flight models, soon learned to create structures which were able to perform well.

In fact, a vessel fitted with a low-power engine may generate a very large wake if, or when, it is unable to propel the vessel fast enough to operate beyond displacement mode.

The good news is that it comes with its own version of the outstanding traction control system also fitted to the Versys 1000, along with a low-power engine mode for poor conditions or simply if you find your heart pounding a little too fast.

The inertia value of the flywheel is "fixed", so low-power engines are under load for a much longer time and internal engine temperatures are usually too high by the end of the test, skewing optimal "dyno" tuning settings away from the optimal tuning settings of the outside world.
