Product details
The Gemfan 1209-4 is a low-pitch polycarbonate propeller built for 65mm micro whoops. With a shallow 0.9-inch pitch and a lightweight 0.21g profile, this quad-blade design delivers rapid spool-up times and aggressive cornering grip, making it highly effective for indoor acro flying or compensating for heavier tiny whoop builds.
Key features
- Quad-blade geometry increases low-end thrust and cornering authority
- Durable polycarbonate construction resists shattering during indoor crashes
- Optimised for high-KV 0702 and 0802 micro brushless motors
- Friction-fit hub allows fast push-on installation without mounting hardware
