Turnigy Heli-Tach 3600 Optical Tachometer 1000~3600RPM
Finally, there is an optical heli-tach available that won't break the bank. Despite the low price, this is a quality unit that will provide you with accurate headspeed readings of your model helicopter. With it's wide RPM range (1000~3600RPM), it can be used for almost any size heli.
The Turnigy Heli-Tach 3600 is very easy to use. Simply adjust the RPM by pressing up or down on the side rocker switch. The LCD will display the RPM value that you currently have set. Once the dots between numbers disappear, the tach is fixed on that RPM. You will then look through the viewing window at the heli blades as it is flying, and adjust the RPM until the heli blades appear stationary. Once the blades appear stationary, the RPM value on LCD will indicate the true RPM of the heli blades.
New Feature: The Turnigy Heli-Tach 3600 now features an ON/OFF power switch on the side of the unit to easily switch the device on and off.
*Note: Never attempt to use Heli-Tach while flying your model. Always have someone else take the RPM reading for you as you fly, or have someone else fly your heli while you use the Heli-Tach.
