[Shop] Fwd: CNC router on kijiji

Thu Apr 13 01:11:47 EDT 2017

I don't think Hacklab's hit the threshold for paying half ($27k in the
bank) so we'll have to fund this ourselves.

I've never played with RC motors... are they reliable, and reasonable for
this application? (This is the motor used:
https://hobbyking.com/en_us/turnigy-trackstar-1-8th-sensored-brushless-motor-2100kv.html?___store=en_us
)

I've found ball-screw upgraded 3040 available on ebay for about the same
price he's asking -- so what's his home made enclosure and rc motor upgrade
worth?Also, would be nice if he could throw in the original parts just in
case we do want to revert something. (if they're around)
