The variable-pitch propeller for your model airplane.

VarioProp Hub & Blade Systems give you 2, 3, 4 and 5-blade configurations with an ingenious system for adjusting blade pitch in the hub. HUB 6A only weighs 5 grams and allows adjustment from 2.5 inches to 6 inches of pitch. The 6A HUB comes in variations to fit 2.3mm, 3.2mm, and 4.0mm motor/gearbox shafts.

Very simple engineering allows quick and synchronous adjustment of the VarioPROP‘s propeller pitch. Just turning one adjustment screw swings all the blades to exactly the desired pitch with the help of a measuring scale provided with each hub, and a pointer. And pitch adjustment is possible without removing the propeller from the model, so after landing you can quickly set a new pitch for the next flight.

The pitch is adjustable in 0.25-inch increments. You can use the same 2-, 3- or 4-blade hub with a large assortment of blade diameters from 5.6 to 15.0 inches, and three different blade profiles -- scale, high-rpm and slow-flyer.

The "Speed" blades for 6A-sized hubs are particularly intended for faster models using direct-drive motors like Hacker B20 18L and B40 S series, Mega 16 Series, UltraFly A30 Direct, and so on. Depending on motor and gear ratio, the "speed" props may be the best solution for a geared system, too, if the target rpm is high. The Scale blades can also be used either direct-drive or geared.
