From dawn to dusk, we hear how electric propulsion is going to save the Earth. Whatever your belief about the hazards of fossil fuel, electric propulsion is coming. When is another matter.
Air taxi ventures based on multicopter designs are drinking up funds by the tens or hundreds millions of dollars, probably billions by now. I don’t have a shred of doubt that these will lead to genuine changes in transportation… but I would not hold my breath until such services become common. I suspect it will be many years yet.
However, today, electric propulsion for ultralight aircraft works quite well, especially when it serves a purpose. For soaring pilots, power is about getting to altitude where they can explore ridge, thermal, or wave lift. Those who love such flying, like me, seek out the best machine that might deliver that capability. Ultralight Design’s Ego trike can.
High-Tech Composite
Anyone who knows hang glider wings will admire both the construction and substantially higher performance of what’s called a rigid wing — more common hang gliders are called flex wings.
Four Stroke Power for Light-Sport Aircraft Aircraft? YES! …a Modern Rotax 582 Replacement
A common question from affordable aviation enthusiasts asks about four stroke engines, either for genuine Part 103 ultralights (available but somewhat more challenging) or for very light aircraft. Such inquiries are commonly for aircraft that have previously used a Rotax 582.
The last two-stroke offered by the big Austrian engine manufacturer — builder of the ubiquitous 9-series four-stroke engines — was the Rotax 582. Producing 65 horsepower and earning a good reliability rating over many years, the 582 has been a dependable powerplant for the lightest powered aircraft that are larger and heavier than genuine Part 103 ultralights.
2020 Sensation!
The one and only airshow in 2020 was the Midwest LSA Expo… about to start this week!
Two years ago, in preparation for the show, Chip Erwin lit up the blogosphere with his Merlin Lite entry (image below). Here’s more about that all-metal, weight-making Part 103 aircraft (our most-read article of 2020, which was then our strongest year ever).
