IMO making a replica is the most time consuming of all methods the get yourself a model airplane, especially when there are no drawings to use. In the future the result of this activity is even transparent so nearly invisible. It is also for this reason to show some intermediate results of many hours of work, for who is interested.

The picture is made without daylight but with use of the original POV but the quality is enough to make the needed compare pictures and to check the plus while carving.

The blue dashes are all 55 pixels long so the plug is nearly finished. Final pictures I have to make with the use of daylight for better quality.
When all the compare pictures are within the wanted accuracy, the plus has to be sanded before use.
