If you’ve been following exciting developments like the Airbus/Pipistrel/Cri-Cri English Channel crossing, or for that matter any of the electric airplane developments, you should know that the ideal electric-powered aircraft today are the very lightest weight machines.
However, another quality is just as important while we wait for scientists to significantly amp up the energy density of batteries. That quality is sleekness and I’ve been watching a Norwegian project from Equator Aircraft. Airplanes don’t get much sleeker than this.
If it needed to be even more intriguing, consider that this project comes from a team that has also been involved with seaplanes, so how about a two-seat electric seaplane? OK, it isn’t ready yet but this is one I will continue to follow closely. Following is some detail on this fascinating entry that again suggests the tip of the spear in LSA design seems intently focused on seaplanes.
Equator’ Aircraft P2 Excursion (abbreviated EQP2) is envisioned as a performance hybrid amphibian aircraft.

Aircraft engine giant, Rotax BRP has reached an anniversary: forty years of making powerplants used around the world by airframe makers of ultralights to Very Light Aircraft. Thus, it was hardly a surprise when Light-Sport Aircraft came along eleven years ago that the Austrian company immediately became the largest supplier of engines … capturing an estimated 80% of the market, even while other ASTM-approved engines are in use from Continental, Jabiru, Lycoming, and HKS. New candidates include Superior’s Gemini Diesel and, of course, the ECi Titan 180-horsepower engine has seen good acceptance. Then we have another batch of engines for kit-built aircraft including Viking (based on Honda), UL-Power, AeroVee (VW), AeroMomentum (Subaru), Corvair, and more.
Despite the many other choices, Rotax has retained a dominant position. I’ve long felt that while it can be challenging to bring a new airframe to market and win some customers, it is even harder to introduce a new engine.

With our friends at the prestigious Flying magazine putting Airbus’ E-Fan on their July 2015 cover, flanked by a major story inside, it seems everyone is following electric propulsion ever more closely. We’ve been doing it for a while as light aircraft are clearly the first place where electric power is best applied. Airbus may be planning an electric airliner but I don’t expect to see that anytime soon. Meanwhile the giant builder of airliners is indeed pushing forward with a two-and four-seat E-Fan.
However, I see another use of electric motors that strikes me as very compelling, and in the very near term. I wrote about a Spanish project earlier and here is another.
Many years ago when I was a young flight instructor, I dreamed up an idea called JERA, the Johnson Emergency Rocket Assist, born out of a small rocket engine that some gearheads were applying to go-carts on steriods.

Some people, myself included, love soaring flight. As the following article from Dave Unwin explains, to use his words, “Soaring flight exercises a fascination that is both difficult to explain and hard to resist, sometimes called ‘three-dimensional sailing.’ Flying a heavier-than-air machine for several hours and hundreds of miles by using the atmosphere as the fuel possesses an undeniable attraction.” As he further explained in a longer article, the downside is getting airborne for soaring flight. Various alternatives have been explored. Some were reasonable; others were too marginal to be enjoyed. In the following piece Dave tells about a new aircraft that might solve this problem, one that can fit England’s innovative SSDR 300 (kilogram) category. —DJ

Article Updated 6/17/15 — ProAirsport announced, “We have now released a priority price of 39,950 British pounds (about $63,000). More details can be found on our website.” This is an excellent value for a motorglider.
