Zenith’s headline read: “All-electric Zenith ‘Sky Jeep’ completes first flight, with plans to transport doctors and medical supplies in remote areas of the world.” Several aviation publishers jumped on the news* from light kit-built market leader, Zenith Aircraft. I’m curious what you think of (1) electric propulsion on any aircraft and (2) electric power for an aircraft used, let’s say, for exploring. If you have an opinion and care to share it, use the comment feature. To date, most electric-propulsion entries have been sleeker designs. Pipistrel has been a leader in this class; they got their start building sailplanes and motorgliders and never lost their preference for clean, smooth shapes. Many others also participated (nearby images). Bye Aerospace’s eFlyer continues its long path toward the market. This development company based its aircraft on Arion’s Lightning airframe, a smart choice as Lightning is so smoothly constructed. This article describes what was then called Sun Flyer.
Should Your Out-Back, Off-Airport “Sky Jeep” Go Electric? Here’s One Answer…
TOP: Electric pioneer Randall Fishman evolved Song into ULS after he adapted electric power (article). BOTTOM — Yuneec e430; it never made it to market.
TOP: Electra One, which first flew almost ten years ago. BOTTOM: One of Pipistrel's earliest electric projects was converting their Taurus motorglider to the tiny motor seen in the image; this is a sensible use of this power source because it is only needed for launching and initial climbout.
So, Why Electrify a CH-750?
The short answer is… not everyone wants to fly a distance at high speed. Distance is already a challenge for battery-powered aircraft and to fly fast either takes more power or the airframe better be very low drag. But what if you only need to cover a shorter distance, perhaps one only served by switchback roads through mountainous terrain? What if getting fuel to remote locations is difficult or impossible. How can someone more swiftly serve such hard-to-reach places? A British project has the goal of delivering healthcare in remote parts of the world. Their all-electric Zenith CH-750 Cruzer took its maiden flight on January 20, 2023. Their aim is to provide a low-cost, rugged, and practical aircraft for use in rural and hard to reach communities, such as medics in Uganda and doctors in rural India.While this solar charging array and "hangar" needs to be transported to a remote location and set up, at least this only needs to be done once. Gasoline would have to be transported regularly.
Nuncats' e750 makes its first flight in late January 2023.

* I commend aviation outlets who quickly published this story. I'm always pleased when general aviation publications pick up on LSA or Sport Pilot kit news. I wanted to take a day to put this electric Sky Jeep in context with other electric aircraft.
