This was the one that they had for immediate delivery but it is the "Gold Racing" (Fiberglass). I personally get concerned with radio reception with an all carbon fuse. In my heli days, Carbon Fuses caused many a problem. Either way, this is a solidly built jet. All of the woodwork is either 3/16 or 1/4 ply. Every component is solid. I too am waiting for the electron retracts!
