RE: RClander T33 for 90 or 120mm edf
When the tail section was glued together, I had some gaps in the very end section. Using the same technique before with BVM V-poxy, masking tape can be used to hold the shape while the glue dries. Add a little paint and the tail section looks much better.
In the last photo, the thrust tube was installed. Painting it black first makes the tail section look a consistent color.
