Everything, the plane itself included, is complete and ok. They only are
demanding yet this one last paper about the propeller/engine/airplane
combination.

prop will be given on a 2000 (constand speed type) certification provided
that the blades are equal. Woodcomp has confirmed that this is the case, so
this might be a solution. Has somebody had any experience with this and can
he confirm this?
