GSC Systems has been propelling the world since 1984

GSC Systems was established in 1984, making it one of the oldest and most globally-renowned propeller manufacturing companies for the light aircraft and airboat industries today. We began with handmade hardwood fixed-pitch propellers and also developed the groundadjustable TECH II and TECH III. With the TECH series, customers are able to replace single blades rather than changing the complete propeller.
Ground-Adjustable 2 and 3-Blade Props

Ground adjustable propellers are constructed with multi-laminated Hard-Rock Maple hardwood. The root section is under-cut then encapsulated using R.T.M. (resin Transfer Moulding) process in precision C.N.C. machined metal molds. Ground-adjustable propellers can be much cheaper and lighter in weight than in-flight-adjustable propellers. Although much less versatile than an inflight-adjustable equivalent, when compared to a fixed pitch propeller a ground-adjustable propeller means that pitch changes can be made to optimize the aircraft for specific payload and flying conditions
2-Blade Mechanical In-Flight Adjustable Props

Over the years as the light aircraft industry has progressed and recreational aircraft have become more sophisticated, GSC Systems recognized that pilots were looking for alternatives to the standard ground-adjustable propellers. To meet this challenge, GSC developed an inflight, cockpit-controlled, mechanically adjustable propeller. After decades of use, pilots consistently report improved performance from their aircraft. Cruise speeds have increased by an average 15 MPH, takeoff and climb-out also are considerably better, and float pilots claim that time to get off water has been noticeably reduced.

Fixed-Pitch Props

Construction of fixed-pitch propellors are such that the wood fibres in the laminations run the entire length of the propeller, allowing it to absorb considerable harmonic vibrations from the engine or crankshaft. Because of this superior strength, GSC Systems will suggest that a fixedpitch propeller be used on any direct drive engine (such as Subaru®, Jabiru® and Volkswagen®. Generally a fixed-pitch propeller is a less-expensive option than an adjustable propellor. Additionally, they are ideal for flyers that wish to be able to attach their propellers and immediately be ready to fly, with no further effort required for adjusting.

PPG Props
GSC Systems have been in the light aircraft propeller market for over 30 years, and have also provided quality products to the small trike and PPG propeller market. With our modern production equipment, we can offer the PPG customer the same high-quality products that our conventional aircraft customers have depended upon. At GSC SYSTEMS we offer you the best of both worlds; a complete line of fixed-pitch props, or choose from our 2-blade and 3-blade fully ground-adjustable product lines. Our PPG propeller database covers the majority of the props that are currently in use. However with new OEM's and new engines coming to market, many prop manufacturers aren’t able to keep up. Our advantage is that we have a CMM in house, which means if you have a unique or damaged prop, we can duplicate the original. Even better, we can even modify it if necessary to
get the optimum RPM and thrust that you require.
