I have built a scale version of the Mclaren Technology centre in my garage. Fitted with the most expensive gear I could find. I have an auto laser tolerance gauge, CNC machine, CF autoclave, 3D printer to name a few pieces of equipment.
Then I wake up and realise I'm actually scumming it up on my office desk with keyboard and screen still there. But I do have fancy tools but not RC specific as I do think you get what you pay for when it comes to tools (plus I use them not just for RC).
