Hi,

I am not a company, I just drew them up for the topflite and toprc fw's because I needed them myself. I print them in a special heat resistant material that does not warp like ABS and is a lot more heat resistant (95°C) than PLA. Problem is the material called Greentec BDP is quite expensive so the fans cost 40.- a piece plus shipping. I can ship worldwide for 10.-.

They bolt directly to the back of the original spinner (both topflite and toprrc) and the toprrc Fan has 175mm diameter leaving around 3mm clearance to the cowl opening.
