The Smart-Fly PowerSystem Sport is an all new design of our unit for smaller models. It is recommended for 60cc and under 3D models or 75cc and under IMAC and Scale models. It features an all new power connector (XT-30) that greatly enhances high current handling over our previous model (15A continuous, 30A peaks) to handle today's high-current digital servos. Since the XT-30 is not a common connector at this time we provide 2 female XT-30s in the package. We also have adapters that go from popular connectors to XT-30 females. The new unit is also lower profile, improved servo connector retention and a fully enclosed design. It provides a power distribution unit for your smaller aircraft that is light weight and compact. The unit is designed for all receivers, end-loading or top-loading. The unit is designed to work with 2S LiFe or 2S Li-ion/poly batteries and regulates the servo voltage to 6.0V. It has a 5.0 volt regulator for the receiver that delivers filtered, clean power. The unit has LED indicators for servo and receiver power. All signals, in and out of the unit are buffered and have RF filtering. The unit also has a built-in Fiber-optic Transmitter for our Ignition Cutoff system. It can be ordered without a Fiber-optic receiver, an Unregulated Fiber-optic receiver or a Regulated Fiber-optic receiver.
