As with any specialized equipment, installation as well as care and use, must closely adhere to the manufacturer’s specifications. This will result in many hours of trouble-free service.

Here are some commonly asked questions on GSC propellers:

If you have a brand new propeller, there is no balancing necessary. All propellers are final balanced at the factory. If, however, you have altered your prop in any way, then balancing is necessary. Propellers must be balanced using a proper balancing method, not simply by weight.

 

The propeller itself is easily assembled on a flat working area (following assembly instructions). All bolts are finger-tight only at this time. The propeller can then be mounted on prop flange on the aircraft and pitch can be set while on the aircraft using the GSC Pitch Adjusting Tool.

 

There should always be a slight gap. This design is to give a clamping action to the blades and not allow them to change pitch in flight. Our experience has shown that a lack of gap is usually the result of over-torquing.

 

Yes, we can replace just the one blade. However, if the propeller is more than two years old, the new blade may not balance with the old blades and it will be necessary to return the old blades and have us balance the new blade to them.

 

Double check your tracking (tolerance of 1/8" at tip). Double check the pitch of your prop (variance from blade to blade should not be more than ½ degree). If propeller has been altered in any way, balancing may be necessary. If vibration still persists, it could be from another source, such as engine crankcase or gearbox. A solution may be to install a liquid-mercury filled style prop balancer. This can remedy most minor vibrations, call GSC Systems.
