Propeller Tenshock, for MONO/HYDRO classes. Duralumin. CNC.

Precision manufactured, bilobed propeller for models of HYDRO, MONO classes.

Wrapping screw-analogue of plastic propeller, from Graupner.
Propellers pro milled from a single piece of Duralumin, on a program milling machine. Precision and sameness of blades: maximum possiblity!

These propellers,  are ideally suited to all classes HYDRO/MONO boats.

Propellers isis practical do not need additional balancing.

The obvious advantages of screws of such performance: their hardness and durability with respect to plastic propellers;

Their accuracy of manufacture and sameness of geometrical parameters of both blades, at propellers o ofthe same type size;
The debugging and additional balancing of propellers (if required), are made with minimal effort.
