GWS EP-1390 13x9 Slowfly RC Aircraft Propeller - GWSEP1390

The GWS EP-1390 is a 13x9 inch slowfly propeller designed for electric RC aircraft where smooth, efficient thrust at lower speeds is the priority. The GWSEP1390 is sold individually, so you can replace a damaged prop or experiment with pitch and diameter without buying in bulk. At 13 inches in diameter with a 9-inch pitch, this prop is well suited to larger electric park flyers and slowfly builds where a wide, relatively coarse blade combination delivers good lift and stable flight characteristics at reduced throttle.

Key Features

• 13-inch diameter with 9-inch pitch, suited to larger electric slowfly and park flyer airframes
• Designed specifically for electric motors — not suitable for glow or gas-powered aircraft
• Slowfly geometry prioritises lift and smooth thrust over high-speed performance
• Sold individually, making it practical as a direct replacement for a broken prop
• GWS EP series propellers are a widely used standard in electric RC flying, with broad compatibility across motor and spinner sizes in this class

What's Included

• 1x GWS EP-1390 13x9 slowfly propeller

What You Need

• Compatible electric RC aircraft or flying wing with an appropriate motor mount and spinner for a 13-inch propeller
• Propeller balancer recommended before first flight to minimise vibration
• Spanner or prop tool suitable for your motor shaft and collet or prop adapter
