It is important to know the head speed of a helicopter in the hover and fast forward flight to be able to maximize the set-up of the engine and blade pitch. Until now, this had always been a costly or dangerous exercise trying to hover the helicopter over an optical tacho on the ground. With the Synchro Meter, your helper simply views the flying helicopter through a window on the meter and adjusts the dial until the blades appear stationary. The in-flight RPM can be read off the large format LCD screen. Suitable for all two blade helicopters and capable of reading head speeds from 1000-2500 rpm.

Spektrum's optional Flight Log is a unique tool that allows you to view the performance of your radio system like never before. With the revolutionary Flight Log, you can now quickly and easily view the real-time voltage supplied to your receiver, how many fades each internal receiver and remote receiver gets each flight, and see if the system received any frame losses or failsafes (holds). The Flight Log is an optional component that was originally designed for testing, but now it is offered as a handy device that gives you a clear digital read-out of your radio performance. The flight log is not required, but for complex aircraft, it provides an intuitive analysis of the overall performance of the radio installation. Some of today's models can be very demanding. The Flight Log ensures confidence that your system is working properly and you have optimized the radio installation.

The Lightning Power Battery Cell Gauge is designed to measure the volts of each cell of your lithium pack. It is simple to use. Plug in a 2-3 cell pack through the balancing connector and read the Liquid Crystal Display (LED). The decimal point represents what volt each cell is reading (refer to the label on the gauge). The connector has 2.5 mm pin spacing. If you have balancing connectors that have 2mm pin spacing, use the separately available adapter. To test packs with 4-12 cell, simply move the gauge over to the next row of pins (see fig. 1). If you plug in the gauge and the LED does not light up, just reverse the connection. You can not damage the gauge by reversing the polarity. Remember to remove the gauge from the battery after use to prevent slow discharge of the battery.
