Hi Davide,
It did take a couple of days to get a response, but once I reveived the response the part showed up on my doorstep within days.

You could always build an early version or Chinese version without the cooling fins.

Hello Davide,
I encountered the same problem with my CA Fiat CR 32. Classic Airframes sent out a carefully packed replacement after receiving my e-mail request. Great customer service!

Good luck,
Jeff
