Here is an RC version of Jim Duckworth's Free Flight "Thistle". Additional photos and details are available on my Thistle Page (http://pease1.sr.unh.edu/aew/rc/thistle/)

Comments and questions always welcome.

The weather here has been so windy all I can do lately is build not fly!

about pushers any down or upthrust needed.
Some top motor mounter pullers/tractor have a lot of up thrust any thouhgts

I followed the design from Duckworth, which had about 3 degrees downthrust (pointing towards the back) with the top mounting this probably has the same effect as a tractor with downthrust because of the lever-arm that the high mount has. If the prop were in-line with the wing I would expect up-thrust appropriate to keep power from pitching up the nose.

Just for grins, look at this: http://lisar.larc.nasa.gov/LISAR/IMAGES/SMALL/EL-1996-00214.jpeg
and the main page, http://lisar.larc.nasa.gov/LISAR/BROWSE/models.html
It has some great ideas.
