Hi David,
Yeah, the pipe on the 140 is pretty big! I would just hang it under the wing - not exactly hidden, but functional. As far as size, my enlarged Chipmunk would not be for competition; so I am not constrained by the FAI restrictions.
How many orders have you gotten for your very nicely engineered electric version?

Will,
I see. While Hanno's Calypso was designed that way, his earlier large Dalotel had a dual pipe tunnel much like how SRT is building his 60 size Dalo.
But I'm curious about this. Do you have a side view drawing of the OS 140? The current 120 e-version is sized to MK spec: 71.4" span and 60" length. What dimensions do you have in mind for the 140 version? Does a piped 140 pull a 2m model along nicely? Would it be better if it was a tad smaller, say, 75" span? That would be a 5% enlargement.
David
P.S. Thanks for your kind words regarding the 120 e-version. We're looking forward to building them. As Doug says, about 8 of them in all thus far.
