Hi Guys,
First, the 60 sized version of the Dalotel originally referred to in this post could be a Zimpro version (very nice ARC kt) or a Dick Hanson version (which was what Chip Hyde won the '84 nats with using a rear exhaust Rossi). Dick actually produced the Dalotel in 2 sizes originally (60 and 120) which were all wood construction (sheeted foam flying surfaces). He also produced a fiberglass and foam version of the 60 sized Dalotel. Dick liked the design so much he later produced another pattern version of the Dalotel (72" length and at least that much span) with plug-in wings and wood fuselage (I have a kit - the fuselage is remarkably light). The fuselage volume/lateral area was much greater than pattern ships of the time (around 1995) making it a bit of a precursor to current 'widebody' designs.
Prettner's TOC Dalotel was kitted by Joe Bridi (I have one of those, too). It was about 68" long with an 1100"sq wing (pretty big!! - those geared 91s must have worked pretty hard, I believe he spun an 18" prop). Joe Bridi must have owned a balsa forest in Ecuador as he packed the kit with wood. His version of Prettner's Dalotel had bolt-on tail surfaces and plug-in wings (pre wing tube; Joe used the captured spar approach and lots of plywood). The design, in my opinion is way too heavy in stock configuration (the kit box and contents weigh about 20 lbs), but could be easily built in 10-11lb range.
Great flying airplane!

PS I saw Chip fly his Dalotel at the '85 nats - very impressive
