Item List


This frame kit is designed for the 3" Toothpick style Y6 by applying the "Solomon's K3" frame concept. Each arm module can be supported by all three arm modules on the opposite layer.  As a result, the upper and lower plates can be eliminated.

  • Wheelbase : 129.9mm
  • Arm module thickness : 3mm each
  • Motor mount plate thickness : 2mm
  • Motor Mount : φ9mm, M2
  • FC mount : 30.5x30.5mm, 25.5x25.5mm, 20x20mm, 16x16mm, M2
  • Weight : Approx. 25g (Carbon only)

Why so many screw holes? It is because the least common multiple of 3 and 4 is 12. Of course, you do not need to use all the screw holes. Each arm module just needs to be secured to all three arm modules on the opposite layer.
