Gemfan Vortex 7x5 Glass Fiber Nylon Electric Propeller (2 pcs)

The Gemfan Vortex 7x5 is a low-pitch two-blade electric propeller for trainers, park flyers and FPV wings that need strong thrust and efficient cruising more than outright speed. It comes in packs of two in the rotation you select.

• Glass-fibre reinforced nylon: strong, light and durable
• Strict dynamic balancing keeps vibration low for smooth handling
• 6.35 mm bore with four adapter rings (3, 4, 5 and 6 mm) for common motor shafts and prop adapters

Choosing rotation: CCW (E) is the standard prop for a conventional nose-mounted tractor motor. CW (R) turns the opposite way, for a pusher mount or the second motor of a twin, where opposite rotation cancels torque. For a twin, order one pack of each.
