Has anyone used the 101mm Electric Ducted Fan Unit from Hobbypartz.com? What the max diameter motor size, mount screw spacing and collet size? I know its cheap, and I know its not great, but I'll looking for a big cheap fan to run at low power. Thank you!

I`ve run that fan up to 4kw. One blade is too long and needs to be trimmed and balanced. 40mm motor dia and 25mm mounting hole spacing. Great fan for the money, but , repeat, it has to be balanced. I use a magnetic prop balancer.
