I make almost all my parts for my heli and design and build 1/4 scale monster trucks,buggys. I have a shoptask machine. Its bigger than a sherline mill but smaller than a bridgeport. It's like a 3 in 1 machine but your not limited with options.I put a digital readout on mine and you can upgeade to cnc. I looked at a serline but decided it was to whimpy for what I wanted to do. Smithys were to expensive not enough power at the time.Check it out @shoptask.com.
