This is a model that was given to me by the late John Dutkowski.
He has reduced the plans by 60% and moulded the fuselage top.
Unfortunately, the model crashed unceremoniously on its maiden flight.
It is now ready for covering and re-maiden.
 

Maiden flight completed today.
Thank you @Frank v B for the assistance with the trimming and to @Andy Hoffer for the pictures.
Now a little bit more trim paint to help with orientation, then another flight soon.
More stable than I expected, better performance, but I will reduce the movements by approximately 50% and add expo for sensitivity around the neutral position.
