Notes

  • A plus quad has one motor at front, back and each side. Orientation is easier and it flies 'like an airplane', but props are more likely to appear in camera (Oscar Liang).
  • The file is a reference example built by Xem Studio from the numbers above (Reference 5-inch build: 220 mm diagonal within Grepow's 210-250 mm class for 5 in props.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
