I use AutoCad 2008, MasterCAM X3, Mach3 for my design, CAM, and CNC software. I love to scratch build everything. I am finishing up on a few projects and may have some time soon to give it a go. I have my own cnc router and access to a laser cutter. How about a few specs on the plane? Looks fun to me. PM me if intrested. Oh yeah, I have inventor 10 Pro but am still learing to use it. I have been doing acad for so long it's hard to break old habits.
