Try Phil Clark at
[email protected] (his website is
http://www.fighteraces.co.uk/ ). He sells a carbon fiber spinner with metal backplate for a 1/5 scale FW-190 that measures 4" diameter x 4.5" length (without the FW-190 fan attached). I needed a spinner for my 1/5 scale Bates N1K2 George and his looked closest to scale of any I could find (and, believe me, I looked EVERYWHERE). I liked it so much I bought two. He lives in England and his supplier is in Germany so maybe buying from him would result in a faster delivery time than buying from the US. His phone number is on his website. Give him a call.
I second the BlueBox pilot idea too. I got one for my George and he looks great.
Good luck.
