OPTICAL MAGIC MIRROR TACHOMETER for RC HELIS AND MULTI ROTOR HELIS

This product is newly developed,it is really impressive and attractive on Beijing Hobby Expo, It can be used for measuring RPM of a helicopter, aerial photography, unmanned aircrafts, multi rotor helis, ONLY for 5 seconds, you can know the parameters precisely such as RPM, setting and performance data, the details are the following:
Features:

■ RPM Measurement Range: 800~4200RPM

■ 4-digit LCD screen display

■ Accuracy: +/- 1 RPM

■ 10 Level aperture adjustment

■ Ultra-wide viewing angle

■ High-speed electronic shutter

■ Measurement remotely and non-contact

■ Simultaneous measurement of fivesets of RPM

■ Super bright and stroboscopiclight, which is suitable for dim indoor environment.

■ It can measure RPM for tinyobjects.

■ Shut off automatically after nooperation for 30 seconds.

■ Power supply: CR2032/LIR2032 button battery

■ Operating BatteryDrain: 3mA, Idle Drain: 10uA

■ Low Battery alarm

■ Weight: 40g





Application:

■ RPM main rotor measurement for allkinds of helicopters

■ Calibrate timing belt

■ The speed measurement of vehicleswith wheels

■ Dynamic balancing calibration forflywheels

■ Vibration frequency measurements

Description:



RCD3063 Magic Mirror Tachometer is a kindof synchronized tachometer, it is an instrument applied human eyes’ persistence characteristic combined nowadays high technology-electronic shutter to realize static object photograph, the appearance and design related to the product has been patented and copy right protected.

The synchronized measurement method won’tbe limited by the distance between the tachometer and the measured target, itcan measure RPM very precisely no matter the distance is more than 10 meters or tens ofmeters, it can also measure RPM of the rotating tiny target so small as 5mm in diameter. That is to say, it canmeasure any rotating target that displays on the viewing shutter.





USAGE

The red button is not only a functionalbutton but also a button for power, press down the red button under the stateof shut off, the tachometer is powered, you can see the RPM data saved lasttime, press the red button, and five sets of latest RPM test data can be checked. As soon as it is switched, P+ is displayed, and then the referenced RPM sets, for example: the first set is displayed P01, the fifth set is displayed P05, so it is easy for RPM comparison between two or more than two target objects.

Button“+”increases the setting RPM value, you can increase the setting RPM value quickly by long time pressing button “+”; Button“-” decreases the setting RPM value,you can decrease the setting RPM value quickly by long time pressing the button “-”, the set up number is displayed on the LCD screen at the same time.



Button“+”increases the setting RPM value, you can increase the setting RPM value quickly by long time pressing button “+”; Button“-” decreases the setting RPM value,you can decrease the setting RPM value quickly by long time pressing the button “-”, the set up number is displayed on the LCD screen at the same time.


As soon as the battery icon appears on the top right corner of the LCD screen, it indicates the battery needs to be changed, One CR2032 is applied; under dim environments, High flash performance can be achieved if LIR2030 battery applied.



The system will be shut off automaticallyafter 30 seconds of no operation.



Measurement

Hold the device, observe the target through viewing shutter(for example: main rotor of helicopter),adjust and set up RPM through button“+”and“-”, when the set up RPM is less than the real RPM of the target, you can see the main rotor rotating in the same direction on the viewing shutter, the closer the RPM toreal RPM, the slower the main rotor rotates, as soon as the set up RPM number equals the real RPM, the main rotor on the viewing shutter is motionless and static, and the read on the LCD screen is the present RPM of the main rotor.

For your information, most people frown at such blatant type of advertising threads.

If you want to advertise, contact the forum operators and pay for a legitimate ad.

Its hard to justify the money for a product I would almost never use. About the only time I use a tach is to verify a new governor is at the correct rpm.

That is a pretty good idea if you can't calculate the head speed using your governor. I have a very old piece of equipment that is used for measuring the rpm of equipment or whatever you want. It works sort of the same way. It has a strobe light and you turn the dial until the object you're measuring appears to stop. Then you look at the numbers and that is supposedly the RPM measurement. Not so good for outdoors, though.

There are a number of such optical tach devices that have been on the market for many years. I have two, one made by Miniature Aircraft and the Skytach made by Model Avionics. Just Google them for their web sites which have all the info about them.

Yes, there are, but this one is very special and made great improvement compared with the previous two.
