|after long time development, time to introducing high performance brushless speed controls, and we're very pleased with what the engineers have done. The current lineup includes 15A, 25A, 40A,70A and 80A controllers, All the Scanner brushless controllers have a rich set of programming features which can be set either by stick commands from your transmitter, via the programming interface in the Scanner programmer.
The processor is a well-proven type, and the software is the result of nearly two years of refinement and testing. The result is extremely smooth motor starts, no matter the motor type, and high efficiency at all throttle positions.
As everybody know there's always a debate about the usefulness of a BEC switch, but after careful consideration we asked Scanner to include the switch on the controllers BEC 40A and higher. There are times when the battery cannot be immediately disconnected after a flight, or a flight started right after connecting the battery. Especially for larger models, the switch is a safety advantage, as keeping it off insures that no one else on the same frequency will inadvertently start your motor.
NOTE: The switch is NOT intended to allow switching off and then back on to fly the model a second time. It in ONLY to keep others from operating your model before you can remove the battery. ALWAYS REMOVE THE BATTERY AS SOON AS POSSIBLE AFTER A FLIGHT. BEC switches (all controller brands) do not disconnect the controller from main flight pack; they only disconnect power to your receiver. While main flight pack is connected to the controller a small current draw always exists, even with BEC switch off. This will cause your battery to completely discharge if left connected, and that will very likely damage the battery.
