GWS EP-1575 15x7.5 Slow Fly RC Propeller - GWSEP1575

The GWS EP-1575 is a 15 x 7.5 inch slow fly propeller designed for electric-powered RC aircraft where low-speed thrust and efficiency are the priority. GWS slow fly props are a long-standing choice for lightweight electric RC planes, flying wings, and indoor or slow-flyer builds where a large-diameter, low-pitch blade generates smooth, steady thrust without over-revving a motor. The GWSEP1575 style code refers to the 15-inch diameter with a 7.5-inch pitch, making it suited to relatively low-KV brushless or brushed motors on larger slow-fly airframes.

Key Features

• 15-inch diameter with 7.5-inch pitch — a high-diameter, moderate-pitch combination that prioritises static thrust over top-end speed
• Designed specifically for slow fly and park flyer electric RC aircraft, not speed or aerobatic builds
• Lightweight construction reduces rotational mass, which helps with motor efficiency and gentler flight characteristics on suitable airframes
• Single propeller per pack — order multiple if you want spares on hand for field use

What's Included

• 1x GWS EP-1575 15 x 7.5 inch slow fly propeller

What You Need

• Compatible electric RC aircraft or flying wing airframe
• Appropriate low-KV brushless or brushed motor sized for a 15-inch propeller
• Matching motor mount or prop adapter to suit your shaft diameter
• Electronic speed controller (ESC) rated for your motor and battery
• LiPo or NiMH battery pack suitable for your aircraft setup
