Just like the Gemfan Hurricane 4023-3 props the new SL 5125 features Gemfan's innovative hub design that's compatible with both conventional 5mm and T-mount 1.5mm style shaft motors.

  • Diameter: 5.1"
  • Pitch: 2.5"
  • Blades: 3
  • Material: Polycarbonate
  • Blade Diameter: 129.54
  • Hub Thickness: 5.5mm
  • Shaft Hole: 5mm and 2mm T-mount with the optional included insert
  • Weight: 2.8/3.0g(with adapter)
Package Includes:
  • 2 SL 5125-3 CW Propellers
  • 2 SL 5125-3 CCW Propellers

Recommended use:

  • AUW well under 400g
  • 15-31g motor of 18mm width or more
  • 3S-4S battery/kv setup
Will work for higher weight quads and have an excellent response but will just feel a bit underpowered due to its lightweight, low drag, low load nature


GF Recommend a motor that’s at least 18mm wide. Smaller will work fine but you’re giving up control performance for the sake of lightness. Depends on what you want, however. Next, many may want to run an ultralight or micro on 6S but more amperage and fewer volts seem to be more beneficial for flight characteristics, flight time and overall ease of use.

The only time we recommend moving up in voltage is when the load on the battery becomes so excessive that it cannot maintain its voltage well. A 5” camera carrying quad or racing quad will have significantly higher loads on them than an ultralight.

We don’t recommend less than 3S, but more than 4S on micros and ultralights is also just going to be adding complexity and increased component risk and cost with not any real-world gains. Because of how ESC’s work, they also prefer normal amperage instead of more voltage and less amperage to the point that higher volts with smaller equivalent capacity will not only be more complicated to tune and operate smoothly, but it will actually be less flight time. Of course, this is all a very general perspective and it entirely depends on what you’re doing.
