Wind Turbine Tail Fin

Aluminum fins keep your Wind Turbine pointed in just the right direction.

Sizing Your Wind Turbine Tail

The length of the tail-boom and the surface area of the tail vane are critical factors in having a wind turbine remain facing into the wind during normal and turbulent conditions. If not sized properly the turbine will shift away from the core wind direction causing a drop in RPM, a loss of power, and a loss of time as the turbine repositions prior to spooling-up again.

Single Fin Tail

Aluminum Tail Fin for a Micro Wind Turbine

This is the perfect tail for any small, home-built wind generators. It is designed to work well on wind turbines using Ametek motors, car alternator-style wind generators, Fisher and Paykel PMAs, among others. If you have a larger turbine or you just like the look of a larger tail, check out our Double Fin Tail.
