Hi Dan,
Yeah, I'm reading this and yeah... I've got one of Dick's Dalotel kits. This is the one from the '90s (originally powered with a ST 2300; 72" long with a span of 78"). he first kitted the Dalotel as a .60 sized pattern ship back in '83-'84 for the 'NEW' turnaround sequence. Chip Hyde won the nats with one ('84 I think).
The newer, larger Dalotel also has an all wood (ok, there's a little foam in it, too) fuselage. Like the Excess, the Dalotel has a relatively large fuselage, but Dick always was ahead of his time . Unfortunately. like his other kits, this does not come with full size plans (maybe just an instruction booklet - I haven't looked in a while). I'm sure plans could be drawn from the kit (it's on my never ending list of modeling things to do...).
As for SPA legal...? I agree with Dan, it sure should be. Maybe somebody can do a plans search and find one that was designed before 1976. I think Hanno showed up at the TOC with a Dalotel in the late '70s (powered with twin, geared 90s as I recall). That reminds me, I also have the Bridi kit of Hanno's TOC winning Dalotel. I'll check the date on the plans...
Later,
Will Bartlett
