One of the interesting speculations in a recent Wired magazine article on the E-Spyder electric ultralight being developed by Flight Design USA‘s (and FlightStar Aircraft‘s) Tom Peghiny invokes turning the lemony limited range of current early electric aircraft into the lemonade of broadly-applied commercial use — specifically in flight schools. *** The first production E-Spyder, soon to be sold for around $30K, will have no more than 30 minutes of range. Yuneec’s two-seat E430, now scheduled for 2012 debut, aims for a 2 hour flight endurance. *** But two hours clearly is more than enough for the typical local flight lesson. And with spare — and charged — battery pack modules ready to go to quick-swap out of electrical “fuel tanks”, flight schools could run training ops as easily as their current gas engined counterparts. *** No distracting engine noise and frame vibration; no lean/enrich fuel settings; no starter motors or smelly exhausts to deal with.
