Comparing the operating costs between typical general aviation craft and a practical hybrid LSA, Randall showed that pilots could count on half the fuel burn at only one-third the cost per flight hour.\u00a0 This would be a huge draw for new pilots and aircraft owners.<\/p>\n<div id=\"attachment_7826\" style=\"width: 538px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/cafe.foundation\/blog\/?attachment_id=7826\" rel=\"attachment wp-att-7826\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-7826\" class=\"size-large wp-image-7826\" title=\"Electraflyer x hybrid\" src=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/Electraflyer-x-hybrid-528x411.png\" alt=\"\" width=\"528\" height=\"411\" srcset=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/Electraflyer-x-hybrid-528x411.png 528w, http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/Electraflyer-x-hybrid-300x233.png 300w, http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/Electraflyer-x-hybrid.png 1296w\" sizes=\"auto, (max-width: 528px) 100vw, 528px\" \/><\/a><p id=\"caption-attachment-7826\" class=\"wp-caption-text\">ElectraFlyer X shown as hybrid, with 1\/3 operating costs of conventional light airplane<\/p><\/div>\n<p>His new ElectraFlyer ULS (Ultralight Soaring) fulfills his goal of bringing practical electric flight to as many as possible.\u00a0 Randall started work on this production ultralight in 2008 which has been available for purchase since late 2012.\u00a0 Randall has logged 31 hours in the machine before he appeared at EAS VII.<\/p>\n<p><iframe loading=\"lazy\" title=\"Electraflyer ULS\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/DnztTPa7aeM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Randall has worked for the last two years with a Czech Republic manufacturer and Slovakian designer to design and build the twin-boom electric ultralight \u2013 for which Randall has worldwide distribution rights.\u00a0 To keep the airplane within Part 103 rules, the structure is a marvel of lightness and clever design tricks.<\/p>\n<p>The trailing link landing gear, for instance, is a bungee-suspended unit that works well on paved or grass surfaces.\u00a0 Its light weight belies its strength.<\/p>\n<p>Each 40-pound wing panel allows easy one-person assembly and disassembly.

Since level flight requires only 3.8 kilowatts of energy, the batteries drain slowly.<\/p>\n<p>This compact system is coupled to an efficient controller, and the ability to pick battery packs that meet specific missions gives the ULS flexibility of operation.<\/p>\n<p>Randall notes that each well-ventilated battery box, a slim stainless steel module that can fit into a slot in each wing root, can hold one or two battery packs.\u00a0 With a single pack in each module, the ULS\u2019 light weight enables soarability even on light days.\u00a0 Putting two battery packs in each module enables up to two hours of powered flight.<\/p>\n<p>With the motor off, the 36-foot wing gives a glide ratio of 20:1 and a sink rate of 234 feet per minute.\u00a0 Not quite an Antares, but at $59,000 ready to fly, not quite the $280,000 of the German superplane.\u00a0 Randall explains that a small group or club could have an efficient self-launcher that can use regular airports and runways, and reduce or eliminate wait times for tow planes, launch queues and other impediments to soaring joy.<\/p>\n<p>Instead, a pilot can regularly enjoy solar-powered flight, expressed as thermals and ridge lift when heavier sailplanes or even hang gliders are grounded for lack of \u201cgood\u201d soaring conditions.\u00a0 Randall reports being able to motor to just the right altitude to catch lift, conditions which sailplane pilots on tow sometimes miss or cannot take advantage of because of low altitudes.<\/p>\n<p>The manufacturer makes a version of the airplane that can be powered by a single-cylinder, four-stroke Bailey V5 or a short-wing version that can be accommodate a Verner\u00a0\u00a0 JVC-360 two-cylinder engine.\u00a0 Only the electric version, though, has both flaperons and spoilers.\u00a0 Randall says the spoilers are highly effective in dropping altitude quickly despite their small size.<\/p>\n<div id=\"attachment_7827\" style=\"width: 538px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/cafe.foundation\/blog\/?attachment_id=7827\" rel=\"attachment wp-att-7827\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-7827\" class=\"size-large wp-image-7827\" title=\"ElectraFlyer ULS3\" src=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/ElectraFlyer-ULS3-528x352.jpg\" alt=\"\" width=\"528\" height=\"352\" srcset=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/ElectraFlyer-ULS3-528x352.jpg 528w, http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/ElectraFlyer-ULS3-300x200.jpg 300w, http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2013\/06\/ElectraFlyer-ULS3.jpg 1000w\" sizes=\"auto, (max-width: 528px) 100vw, 528px\" \/><\/a><p id=\"caption-attachment-7827\" class=\"wp-caption-text\">Randall Fishman uses flaperons, spoilers to land on the selected spot during windy day. \u00a0Camera on right rudder captured flight on video<\/p><\/div>\n<p>Looking beyond the USL, Randall has a trio of motors; 30, 60 and 90-horsepower waiting in the wings with news to come soon.<\/p>\n<p>Explaining that a production airplane such as the ULS is essential to getting electric aircraft in the sky in large numbers, he noted that even dedicated home-builders would take years to get a single airplane to demonstrable success, making for a small representation within general aviation.\u00a0 Randall\u2019s inventive mind is obviously in top gear these days, seeking out new ways to bring electric flight to a broader audience and expand the number of proven electric craft.\u00a0 We can only wish him good fortune with his ventures.<\/p>\n<div id=\"facebook_like\"><iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=http%3A%2F%2Fcafe.foundation%2Fblog%2Frandall-fishmans-electraflyer-uls-a-gateway-plane%2F&amp;layout=standard&amp;show_faces=true&amp;width=500&amp;action=like&amp;font=segoe+ui&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:500px; height:80px;\" allowTransparency=\"true\"><\/iframe><\/div>","protected":false},"excerpt":{"rendered":"<p>Appearing before attendees at the 2013 Electric Aircraft Symposium, Randall Fishman\u2019s spoke of great accomplishments and grander visions.\u00a0 \u201cElectraFlyer ULS &amp; Electric Ultralight Airplanes, the path to approval for all electric aircraft?\u201d showed ElectraFlyer\u2019s history and the ambitions Randall would like to play out.
