A ground-adjustable propeller is a simple type of aircraft variable-pitch propeller where the blade angle can be adjusted between pre-set limits of fine and coarse pitch.[1] As its name implies, a ground-adjustable propeller may be adjusted only when the aircraft is on the ground and when the engine is not running.

Ground-adjustable propellers, which are mostly used on light and very light aircraft, are much cheaper and lighter than more sophisticated and versatile in-flight-adjustable propellers. A ground-adjustable propeller allows pitch changes to be made, although not in flight, to optimise the aircraft for current payload and flying conditions.[2]

To adjust the propeller, the blades are loosened in the hub, a new angle set and then the hub tightened.[3] The process is one of compromise, and of trial & error. After a flight, if, say, climb seemed too sluggish, the pitch angle may have been set too coarse and would need to be made finer. Alternatively, if the aircraft reached take-off speed quickly but struggled to reach a comfortable cruise speed, the pitch would need to be coarsened. The person making the adjustments would be advised to do so in small increments until a satisfactory outcome were reached.

Improve your Aircraft's performance and looks with our 3 blade Rotax propeller featuring our new PowerSweep blade planform. This propeller is manufactured using an internal pressure, closed mold system to produce a hollow, one piece blade. This process yields very repeatable blades with maximum strength, durability, and low weight. Don't confuse this propeller with other propellers that are manufactured as two pieces and then bonded together afterwards. This propeller has the strength and durability to give you thousands of hours of trouble free flying.
This propeller features a co-cured bonded stainless steel leading edge for erosion and FOD protection. The two piece hub is manufactured from aerospace grade aluminum and is either alodined or anodized for corrosion protection.
Our Pitch Pin Indexing System allows its users to set a broad range of pitches, using the system's Pin Indexing system to make adjustments. The pins that come with each propeller allow 12 inches of pitch adjustment, affording maximum performance within an efficient aerodynamic envelope. The Index Pin locates the blade and then you simply lock the blades in place..
Our 3 Blade Rotax propeller is suitable for use on the 912 80HP, 912S 100HP and 914 115HP. The propeller is available as a 72' or 68' diameter and can be trimmed down to 65' diameter.
We have a composite spinner available for these propellers in 9.5' diameter.
