We've been following Electra's ultra-short takeoff and landing electric hybrid prototype for some time and now the company has unveiled its EL9 Ultra Short production model that is designed to carry nine passengers at 175 knots (201 mph, 324 km/h).

Last time we looked at Electra, the company was working with the US Air Force to adapt its EL2 Goldfinch two-seat prototype for military applications where the ability to take off and land from very short runways is desired. Now, the ultra-short and take off technology is being used to create a production passenger aircraft that can carry nine people or 3,000 lb (1,360 kg) of payload over 330 nm (379 miles, 611 km) or 1,100 nm (1,265 miles, 2,037 km) when ferrying unladen.

The new EL9 uses the same hybrid eclectic system as the prototype as well as the blown-lift technology that allows it to carry out postage-stamp takeoff and landings on fields the size of a soccer pitch with a take off and landing requirement of only 150 ft (45 m). Though these strips can be visited by helicopters and eVTOLs, Electra claims that the EL9 can do so at a third of the cost and with much lower emissions and noise.

This may not seem to be too important a capability, but in remote, mountainous areas, it can be a real game changer. I spend a lot of time in the back country and it's always amazing to see how many tiny airstrips, both public and private, there are that the local population rely upon for commerce and emergency services.

In addition, the hybrid system allows for much more independence. Unlike pure electric aircraft that require chargers, the EL9 is self-charging, so it requires no such infrastructure, as well as giving it longer range and an emergency reserve. The fly-by-wire systems also allow the aircraft to fly with one or two pilots with great precision on instruments.

"Today’s reveal of the EL9 showcases the dedication of our incredible team and partners," said Marc Allen, CEO of Electra. "This aircraft is more than a new design – it's the gateway to a cleaner, quieter, and more affordable future for regional travel. With the EL9, we're not just making sustainable aviation a reality, we’re redefining how people and cargo move through Direct Aviation, a new category of safe and seamless travel that brings air mobility closer to where we live, work and play."

These guys have got it absolutely nailed on.
All electric aircraft have very limited use because of their (lack of) range and huge deadweight of the batteries. Maybe in the future those problems will be solved, but right now, the technology isn’t even close.
A well executed hybrid is the perfect blend of technology laced with economic and functional realism

Agree that hybrid is good choice. Basically use smallest battery as possible to (1) run motors and (2) provide some reserve when (not if) the main power plant (turbo-generator) goes down. One critique: They claim 150’ take-off. I presume this ONLY refers to ground roll, w/only one pilot. What happens to TO&L distance, range/payload, +/or requisite power w/a full load of 9 pax? What actually counts is "Balanced Field Length" (BFL) that must consider abort distance/braking, the loss of a prop (or engine, thrust loss, adverse yaw), high altitude & hot day (power & thrust lapse), all while clearing a 50' obstacle!! Wait until landing issues are considered (high-lift needs blown wing, but thrust increases speed, which makes longer landing distance +/or needs spoilers etc.). Devil's in the details. Opinion: Fully support SSTOL/STOL, but expect current design to grow (as most do) or advertised field length for T-O and Landing to increase, as reality sinks in.

9 passengers is just about spot on for that kind of puddle-jumper. If a few seats are empty, they can carry more freight.

I wonder whether the STOL chops also go with resistance to winds. There are lots of locations where landing or takeoff with a conventional lighter airplane is pretty dodgy, but if you can put down in 50 m instead of 200-500m that could make fighting gusts less dangerous.

The facts actually show that hydrogen fuel cells are the future and batteries will still be used for the VTOL part of the "e" trip needed as back up for the more efficient but less powerful design on purpose fuel cells for the vast majority of the trip.

Interested in the turbo-generator. what fuel is used and how heavy. It could be the magic bullet for lots of lightweight electric planes.
