This upgrade fits the Robbe Sea Bee foam ARF.
The upgrade comes with a protective belly skin to protect the foam from the ground when it's not in the water.
It is made with .030 PETG plastic , the same stuff soda bottles are made with so you know it's tough.
The canopy is made with the same material and is a direct copy of the foam hatch / canopy.
That is to say it fits right over it. There is enough material to overlap the hatch seam for a better water seal.
This makes the original hatch work as a frame to attach the canopy to the model and retain the original hatch configuration.
The installation is fairly straight forward so no instructions are available.
The plastic is compatible with almost any adhesive or paint .
To be safe use a piece of scrap to do a test.
