Menu point B is used to set the lowest throttle position. Watch Out! Output [CH5] can be directly controlled by the throttle stick.
Using an electric model bring the throttle stick to the position at which the motor just does not start. If the stick throw has been correctly adjusted as described at menu point A (or the speed controller has been programmed to the stick throws), the necessary gas position should be achieved at the lowest position of the throttle stick. Some speed controllers provide a special mode that allows for a quick start-up in case of aborting an autorotation landing. Here there is a larger area between the actual „motor off“ position of the speed controller and the point at which the motor actually starts. Also in this case move the throttle stick to the point at which the motor is just before to start, so that MICROBEAST PLUS can determine the effective throttle range correctly.
With a nitro/gasser model you bring the throttle stick to idle position or a slightly increased idle position (not „motor off“!) so MICROBEAST PLUS can determine the effective throttle range in the next step. Using the RPM Governor without an auxiliary channel to control the RPM Governor (see Receiver setup menu point B and following), this position additionaly will be used as idle position when performing an autorotation maneuver. So you should set the throttle as high as necessary here that the motor will maintain a stable run and doesn‘t quit during the autorotation maneuver.
When setting the low throttle position make sure the Status-LED lights up in blue color (both electrical as well as nitro). This means that a new valid throttle position has been detected. If the Status-LED lights up in red then the throttle stick is too close to the throttle stick center position. This is not considered optimal and therefore can not be used as throttle position. In this case check the setting of the transmitter and the programming of the speed controller or readjust throttle servo, carburetor position and throttle linkage rod.
When entering menu point B initially the Status-LED is off. As long as you do not move the throttle stick, the currently stored position will not be changed. So you can skip menu point B by a brief push of the button without changing the throttle position when performing subsequent adjustments in Setup menu or Governor setup menu. Conversely this means that you need to move the throttle stick at menu point B at least once to change the current throttle position!
When finished briefly push the button to save the configuration and to proceed to Governor setup menu point C.
