Tokyo Institute of Technology students, with a grant from Panasonic, used 160 AA Oxyhydride cells to power a small motor on their adapted HPA, driving the plane to about 5 meters height and 400 meters distance. Calculating a sale price of $5.00 per 4-pack, 160 cells would cost $200. 400 meters = 1,328 feet, or a quarter mile. Flying 1 mile on this aircraft would cost $800. http://panasonic.co.jp/corp/news/official.data/data.dir/en060718-3/en060718-3.html San Carlos, April 24, 2009 46
From the University of London Press Release:. “Master Master of Engineering (4th year) ear) project students ha have e modified an aircraft to fly fl on electric power, in association with Anglia Sailplanes and AeroElvira Ltd. “The first flights took place on 20/21 September. Test pilot, Derek Piggott, described the modified aircraft as a "delight to handle". “The aircraft was modified by the addition of 8 underwing pylons attached by removable straps. The pylons were fitted with 16 propellers (280 mm in diameter) driven by electric motors and powered by lithium-ion batteries supplied by Ripmax PLC. The motors were activated by a wireless link by the pilot in the cockpit. A permit-to-fly was issued by the British Gliding Association Association. “The project involved over 3 MEng Project groups over a period of 5 years, including for example the following students (now all graduates): Ross Shepherd, Stefan Wurwal, Mark Saunders, Hamza Baker, Mikel Alonso, Morten Christiansen, Sami Ghamloush, Mehrtash Lotfian, Mohammad Ali Sarkandi, Junaed Wahid.” News date: 24 September 2008 Graupner p 900’s cost $ $60 each, , so the motor cost was $ $960. .
