First Person Flight (FPV) is advancing within the RC industry and among hobbyists. The new Guardian Stabilization system is an on-board system that provides extremely high resolution stability for your fixed wing and elevon aircraft. The Guardian system is used in concert with the OSD Pro and provides both minimal and advanced setup features. You can as well control the gain using a dial on your transmitter while in flight. When installed and controlled through the OSD, the Guardian provides an artificial horizon indicator on your OSD screen.
