The Gemfan 5125 props are the lightest 3-blad props at the market. It is a great option for ultralight frames with T-mount motors like TWIG ET5 5‘’ Toothpick Quad. More responsive and very well-managed throttle control. The best thing about this prop’s hub design is that it can also be used with conventional 5mm motor shafts like 1506 Motors. Packed with the T-mount hub insert adapters for a 1.5mm center hole, so it can also use on 1404 Motorsand 1505 Motors.
