When this series started, Icon’s shapely A5 LSA seaplane topped the list. Handsome as it is and like most seaplanes, A5 is not particularly fast. The subject of this second in the series of 50 aircraft is Porto Aviation’s Risen. You might say it is on the other end of the speed spectrum Risen rips! This one challenges all others in the speed contest for LSA (and later, mLSA). Our #2 video on Videoman Dave’s immense library has garnered 700,000 views. That’s particularly satisfying as Dave was able to use footage from my first solo video effort. I was at Aero Friendrichshafen 2015 when Risen made its debut. Videoman Dave was not able to attend that year but I hit it off with developer Alberto Porto and he consented to work with me. I was just learning how to shoot a video so for this one to go over well speaks loudly about how much pilots love Risen.
Updating RisenI am further pleased about that 2015 Risen video becoming so popular because at Aero 2023, I again shot my own video and present it for you below. You can view and compare the 2015 Risen announcement and predictions with the current state of the art: SuperVeloce. In fact, the new video has enough quality information in it that I will summarize comments below and let you listen and watch for yourselves. Alberto's English is good and you can understand him well. In this way you get the story directly from the designer. Speed Range — Top end, using true airspeed, can exceed 240 knots! This number puts SuperVeloce in the league of Lancair and Glasair, owners of which have become Risen or SuperVeloce owners. True airspeed is different from indicated, as all pilots know. Alberto notes that never-exceed speed is 210 knots indicated. Risen achieved high speeds using only 100 horsepower from a carbureted Rotax 912ULS. Now with the 915iS and 916iS, power output jumps to 141 or 160 horsepower. Even with the most potent powerplant, SuperVeloce is far more fuel efficient than engines in a Lancair or Glasair. Structural Upgrades — To accommodate so much extra oomph, SuperVeloce required significant engineering and analysis plus lots of testing. The wing got smaller but the fuselage stayed the same, visually. In fact, it had enhancements under the skin to strengthen SuperVeloce and to better protect it again flutter, a serious aerodynamic phenomena affecting faster aircraft. SuperVeloce and Risen are built primarily of carbon using monocoque construction where the fuselage body provides structural integrity. Wing Changes — In addition to bolstering the underlying structure, Alberto reduced span from Risen to Superveloce by about a meter, more exactly 80 centimeters or 31.5 inches. When he did this, glide performance declined from 23:1 to 20:1, though that is still strong enough to enter motorglider territory. Handling — Alberto notes that he cannot be impartial as Risen/SuperVeloce is his own design; to his credit, he acknowledged he is biased in favor of his creation. He defers to his customers for a more impartial view. Nonetheless, he expressed that he finds the handling easy and straightforward although he also cautions that to fly this airplane you must prepare. This is not an ultralight of the 1990s. Fleet Size — Since its debut in 2015 (production started later), 29 Risen aircraft are flying in several countries. In the USA, Porto has registered 10 aircraft, a worthy number in such a short time for a premium aircraft. V-tail Advantages Description — Alberto's choice of a V-tail was deliberate and built on experience from such legacy aircraft as Beechcraft's Bonanza. Reducing three fins to two means less interference drag while losing no control. Pilots who are puzzled about how a V-tail mixes rudder and elevator input should simply fly conventionally, Alberto said. The mixer will do what you want. V-tails are known for their efficiency and that is a watchword of SuperVeloce's development. Enjoy the twin videos!
