The TT62 has 2 Thielert 350 HP V-8's located in-board and actuating, through transmission drives, two propellers positioned where turbojets are in a business jet. It is flying since 2/05, cruises at 240 Knots at 20,000 ft and has a standard range of 1,700 NM consuming around 18Gal./h. (Yes, 18 Gallons…Cessna, Piper and Beech, wake up, here is the future: America to Europe in 3 legs and back with less than 800 gallons of jetfuel.) It will constitute an interesting low cost alternative to the new minibusiness jets popping around everywhere. The other application of the 350HP sofar is a private German STC program for a Beech Duke.
