Evening all,
Just finished work and a few minutes to play!
Have read the thread on the latest from Graeme and have nothing really to add other than the "mystery black thingy" does look very similar to the Ryan SCW photo, but wasn't the Ryan a three seat cabin monoplane with a low set wing? The Challenge cockpit looks to be a single seat width, its aft-quarterlight window seems shallower than the the SCW and is it a mid-winger?
