ONE PIECE CAST(No weld-on blades)

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. Insure your investment with a one piece cast propeller using premium grade Aerospace stainless.
