You can also combine the MULTIPLEX WingStabi with this safety switch. It is mounted on the outside of the model in an easily accessible location. The switch allows you to arm the drive after you have plugged in the battery without causing any spark. This prevents the drive from starting up unintentionally (e.g. when you plug in the battery or carry the model to the launch site). The professional version is an elegant switch actuator with magnetic switch for the hull assembly. The operating states “battery plugged in” and “drive armed” are signaled via a two-color status display with fiber optics.
