Our 3D prints are designed and printed by Noozle3d, if you want custom colors of our prints you can contact them directly. Our new low profile ducts are…well not really ducts. We’ve found that with the low profile duct, there is no noticeable loss in thrust and the advantage is lower weight and better aerodynamics. It really becomes more a prop guard. Weight of original ducts – 87g Weight of low profile ducts – 71g
