The proven blade design of the G-SONIC propellers has been known for their high resistance that has led to an increase in torsional strength, bending strength and tensile strength. Newer manufacturing processes has made the G-SONIC propeller series even more efficient generating more thrust at reduced noise levels. Manufacturing is drawn on the latest science using advanced CAD/CAM systems and machines. Such precise approach optimizes the concentricity and blade tracking during a wide range of flight conditions.


  • Designed for nitro and gas airplanes
  • High efficiency over a wide range of operation.
  • Extensive CAD/CAM process for optimal results
  • Stronger materials guarantee lower noise levels


  • One G-SONIC Propeller


To avoid possible injuries please take note of the following safety precautions.

  • Modifications to the propeller are not permissible!
  • Never stand in the hazard zone in front of or next to one side of the propeller plane!
  • Never touch the rotating propeller!
  • Never re-use a damaged propeller!
  • Never allow the propeller to exceed the stated maximum permissible rotational speed (RPM, see table).

Nice made prop. This prop was used on a YS 140 sport. Was a little more load for this engine in hot weather using 13% nitro. This prop is more suited for the DZ or limited 140. If your are using 20/20 fuel the 140 sport could run this prop in my opinion. This prop has low noise. I did try it on a DZ170 using 13% nitro. Turned 8200rpm. Prop handled it great.

G-Sonic 16 x 12 3 blade prop
Used the prop used on an H9 Beaver with an Evolution 33 engine. Performance was the same as the recommended 18 x 8 2 blade prop but quieter and gives a more scale look to the plane.
