Does Alpha have the tiny little motor that could? Article updated 6/22/21 —DJ That sounds like an old childhood story (“The Little Engine that Could…”) but here we are in the new millennia with electric cars, huge wind farms, vast solar collector projects, biofuels, and more. Subsidies are pouring in to electric projects around the globe. Hundreds of developers building “urban air transport” multicopters are raising millions of dollars. Will human-flown conventional aircraft join the electric parade? One company has pursued the electric dream further than most. This story is about a group in Australia that aimed to set a new world record, one of a rather different sort. In this case the team plans a “record attempt flying a Pipistrel Alpha Electro plane,” Australia and USA Pipistrel dealer Michael Coates wrote. “[The flight] will start at Parafield Airport at 7:00 a.m. on Saturday June 19, 2021.” Total distance, Michael added, will be 1,150 kilometers, which “will shatter the previous record of 750 kilometers flown in September 2020 in Germany.” This project hopes to break the previous distance by more than 50 percent.

Team Alpha Goes the Distance
The attempt to set a new record is being led by Eyre to There Aviation Managing Director, Barrie Rogers, who undertook the first ever electric flight in South Australia in 2020. Pipistrel Alpha ElectroFAQs About Alpha Electro
Pipistrel Alpha Electro started development in 2014; it was released to the public in 2017. "Electro was an immediate success with more than two-dozen orders after its initial 2017 release," boasted Slovenia-based Pipistrel.

Here are two videos about Pipistrel Alpha Electro. The first is from a reporter in Australia focused entirely on the electric-powered Alpha. The second is my review with U.S. representative, Rand Vollmer, covering the broader Pipistrel line. https://youtu.be/uMrLHeKJA80 https://youtu.be/ZmnlSaXHGWQ
