This might seem like the wrong place to put this, but the project will be posted on this thread as it develops, so hopefully the mods will be gentle with me.
I'm working on a new project and I need a hover/fan drive with is about 30mm diameter which I can build the thing around. I've looked at small computer cooling fans but they quite gappy and I wanted something more dense, i.e. lots of blade no gaps.
Does anyone anything suitable in their bits box, or can anyone suggest a source for it?
