Mr. Gracy would have a field day with this one and rightfully so.<br />This is for the polished and wealthy crowd but it's not a seaplane that anyone with waterplane experience would be interested in. Starts at $400,000 USD, Rotax 100, no step on the egg shaped hull bottom, nosewheel, tiny wings (so presume high stall), zero specs that I could find, only one picture of it landing on the water and then water massively through prop, (engine mounted on vertical stab) totally incapable of being beached because of the nose wheel and if you leave the wheels up, you wreck the canards (hydrofoil), and finally, an electric canopy that is guaranteed to kill you when you flip over on that likely bounced landing. (but you will have a great view of the lake bottom) When you look at the plane from the side, you can't help but see the CG is too far back. Oh, supposedly designed for snow skis also but no actual pictures of it on snow, just flying over.<br /><br />Wow. Hard to believe anyone would be crazy enough to build a seaplane with no practical seaplane experience.<br />A French Phantasm. <br /><br /><a href="http://www.lisa-airplanes.com/">www.lisa-airplanes.com</a>          Don Maxwell - Oct 06,2011   Viewers  | Reply     I don't know what they do about beaching with those hydrofoils up front, Ken, but I see a tailwheel in the photos. It looks as though the stab is large enough to produce positive lift. The death canopy looks sleek, but it's so low that you might not be able to see the water straight ahead through it when step taxiiing. I hate the hokey drawings, but some of the photos and the video appear to show an actual airplane in flight. It sure makes one wonder when more than half of the video is of nothing real.          Kenneth Leonard - Oct 06,2011   Viewers  | Reply     Interesting, in this video, at 1:29, it shows the nosewheel version. <a href="http://www.youtube.com/watch?v=HKO06oj7u3k">http://www.youtube.com/watch?v=HKO06oj7u3k</a>          David Myers - Oct 06,2011   Viewers  | Reply     looks retarded and a handful to operate. just cant beat a searey          Chris Vernon-Jarvis - Oct 07,2011   Viewers  | Reply     One of the major problems for water planes is the very poor aerodynamics of hulls that are designed to work on water. The crisp lower edges, edge strakes for water control on many planes, the volume required up front for buoyancy and the step all play a significant part in keeping, for instance, the Searey to under a hundred MPH cruise. (Not to mention canopy, struts, legs, wheels etc but they are design compromises.)<br /><br />It seems the designers of the LISA looked for a way of eliminating some of those and may just have found it. Hydrofoils lift the hull out of the water at moderate speed getting rid of water hull shape, step, strakes etc.<br /><br />I may not be in favour of some of their other choices, but they are hardly the first to do them, eg, Seawind, It will be interesting to see if they have by passed some of the Seawind's deficiencies. I watched a Seawind trying to take off and it took three tries on our lake and on one of them had terrible porpoising. Maybe the hydrofoils by pass that problem.<br /><br />There were some experiments a while ago showing that seaplanes with hydrofoils worked really well. Don't write this off as an idea.
