Weighing 20 to 24 kilograms (44 to 52.8 pounds), depending on batteries, the system will enable a climb rate of two meters per second (384 feet per minute). The motor package can be removed easily, allowing the airplane to revert to pure soaring form. Ruppert explains this adaptability: \u201cOnly a few parts remain permanently installed in the airplane, the remaining extra weight in the glider is correspondingly low.\u201d<\/p>\n<p>A specially-designed folding propeller\u2019s vortex remains under the tail, and when powered off and folded, adds little drag to the fuselage wake, while the added weight might have a positive effect on the airplane\u2019s penetration in soaring.<\/p>\n<p>Prices for the motor package and delivery schedules will be announced in early 2013.<\/p>\n<div id=\"facebook_like\"><iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=http%3A%2F%2Fcafe.foundation%2Fblog%2Fthe-electric-archaeopteryx%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>Ruppert Composite has been flying the up-market Archaeopteryx for the last several years, with pilots hopping off hills in the highly efficient, advanced hang glider.
