Until now, your only primary power choice was the "old way", a combination of electro-mechanical components that haven't significantly changed in half a century.
Now you have a choice...the PPS.
The PPS is a carefully-engineered and highly-qualified device that eliminates the need for you to engineer and manufacture your own primary power circuit. This not only puts an end to common errors in homemade circuits, but the solid-state construction of the PPS proivdes extremely high reliability when compared to the failure-prone solenoids, relays and contactors used in traditional circuits. In addition, the plug-and-play design of the PPS installs in minutes, saving you valuable time and allowing you to fly that much sooner.
