RE: plans and specs
Torino,
The Calypso was indeed a Prettner design and won the World Championship in 1984 I believe. It was kitted by a company called Model Tech and came with a prebuilt wooden fuselage and pre sheeted wing/stab and a fiberglass cowling. Very simple to put together and flew very well. It just wasn't as "stylish" as the planes of that era. I don't believe there were plans available for it in the US but I would check German Model magazines as most of Hanno's planes were available in plan form in that country. The plane was flown with a "Hanno OS .61 pumped w/pipe" or any good rear exhaust engine mounted inverted with the pipe in a tunnel underneath the wing. I have seen a couple of these show up on Ebay... and as the rule goes: there is ALWAYS another one. Hope you can find one... ask in this forum.. who knows....
