We have taken the newly released Freestyle and added an airfoil to the wing and enlarged it. The wing rather than being cut from 9mm flat sheet EPP it is CNC hotwire cut with an airfoil. This allows a rounded leading edge and thin trailing edge. The airfoil shape along with the skin formed by the cutting makes for a stiffer and more efficient wing. The handeling and behavior of the plane is as good as the original but it has more presence in the air and better speed making it a better outdoor plane.
More details can be found on the Freestyle thread on .
Here is a set of for building a 42" 3D plane.
Here is a that shows the Welders hinge technique.
The kits come with a hardware pack that includes the spar and pushrods. The other required parts are listed below.
50 gr motor
18 amp speed control
Plywood motor mount
9 gr servo X 4
