Spindle 400w Brushless (BLDC)

I am looking at building a machine for RC airplane fabrication. Almost all work will be in balsa wood or 1/16 thru 1/4 plywood (the type made for model building). To keep gantry weight and noise down I am thinking about using one of the 400w brushless Chinese spindles that can be purchased on ebay, mounted on the Inventibles universal spindle mount. Does anyone have any experience with this setup, if so please share your knowledge.

i think of buying this DC spindle motor because it recommend and low noise.
