I'm going to use a drive shaft bought off of eBay. Look up item number 152808938160. It has a 4mm inner shaft and a 9.5mm sleeve. Both are stainless steel. Comes with a universal coupler too. You have to specify what size motor shaft when ordering. Of course, I won't be using the propeller that came with it.
