i'e run shapeways printed autoscales and the material is tuff and i'm sure you've tested it's durability. those front wings take a beating
nice to see someone take the reigns with Mantis out of production. at least i assume he's not producing anymore as we haven't seen anything from him in ages.
i'm shocked someone hasn't used 3d printing to make a more current version autoscale with adequate motor wire clearance.
