==Design and development== The Emrax 228 is a brushless 130 volt design producing a peak of {{convert|100|kW|hp|0|abbr=on}}, {{convert|55|kW|hp|0|abbr=on}} continuous, with an outrunner coil. It has a 98% efficiency. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive.<ref name="WDLA15"/><ref name="Emrax228">{{cite web|url = http://emrax.com/products/emrax-228/|title = Emrax 228|access-date = 29 April 2018|author=Emrax |work = emrax.com}}</ref> <!-- ==Operational history== --> <!--==Variants== --> <!--==Applications== --> <!-- ==Survivors== --> <!-- ==Engines on display== -->
