I hope you are able to get access to a wind tunnel, I am very interested to see the results of the test.
Do you by chance have access to an unmodified Duellist twin to compare the data with? I am intrigued to see how much of a difference that reduce frontal area, improve the nose and nacelle transition can make.
I would love to take something like the "Velocity" and create a dual tractor powered version.
Also as I have an real interest in the particular area that you are dealing with I am curious to the results such efforts make .
I would love to see more instrumentation for our models become available, to allow for us to obtain more data.
As far as what you threw out...
Sounds a bit like towing a banner to me...
