The development of the HELIX Ultra-Fast Propeller was accompanied by a continuing process to achieve the best possible combination of lightness and stability. This process will never be completed. There are already more Ultra-Fast variants in development that will meet the increasing demands of customers.
In competition with other manufacturers HELIX offers the greatest stability in the respective weight category. comparative_table
Thanks to their lower weight, HELIX innovative UltraFast models not only achieve a lower mass moment of inertia but also significantly increased acceleration.
In addition, they combine the HELIX usual standards of fixed angle models.
The Helix UltraFast series is now available in various types from very thin to very thick profiles, applicable for different flying styles: fast climbing, cruising, sportive, competition and more options.
In comparison with the standard product, the UltraFast has an average weight reduction of 30%. The lightest type H30F –ES double-blade weighs only 510g.
All UltraFast propellers are the optimal compromise between stability and weight.
Therefore before released the new lightweight, Helix has been working long time on an optimal result of a best possible combination of lightweight and durability. HELIX UltraFast propeller is ultra-light weight, meanwhile maintaining a satisfactory level of robustness and durability without sacrificing Helix standard on quality and precision. At the same weight category, Helix propeller still has the best stability in comparison with other manufacturers.

Mount the propeller
Download the handbook for reference to mount the propeller blades onto engine flange. An adjusting tool will be supplied in dispatch of the ordered propeller, with which precise setting of the blade pitch can be easily done.
The blade geometry of ground adjustable propeller is the same as the fixed pitch one, but blade angle of attack is adjustable for different settings on ground. The propeller is attached to a hub, which is available for 2- 3- and 4-blade design with the same radius. The precision of blade root in combination with the aluminum hub surface allows slight angle adjustments within the hub during installation.
