Power Tech

Description:

PowerTech! Stainless Steel Propellers are cast in one integral piece in
a ceramic mold. This process is used by all motor manufacturers as
well as a few leading propeller manufacturers. The extra expense is
well worth the outlay compared to the cheaper "weld-on blade"
process.



In the weld-on blade process, blades are manually placed against the
round cylinder barrel and welded in place. Errors in blade placement
and welding "heat draws" can result in inconsistent pitch, rake and
dynamic balance. Additionally, a welded joint is more prone to
breaking under peak loads.
