SPEKTRUM DX3S USER GUIDE

To select the telemetry sensor settings, rotate the Rolling 

Selector and place a box around Tele- SPEED then press 

the Rolling Selector. The surrounding box will flash. 

Rotate the Rolling Selector to select the desired sensor 

setting for adjustment then press the Rolling Selector.

Use the Rolling Selector to select the sensor parameters 

to adjust.

Press the Rolling Selector and a surrounding box will 

flash.

Use the Rolling Selector to adjust the value and press the 

Rolling Selector to select.

To return to the main screen press and hold the Rolling 

Selector for more than three seconds.

Tele-SPEED

Zoom - The Zoom setting sets the maximum range or 

boundary of the Speed unit. 

Unit -Select RPM, MPH, KM/H display units

Roll Out - The Roll Out function is only visible when the 

unit is set to MPH or km/h and is the internal calculator 

that allows rpm data to be converted to mph or km/h. 

When the Roll Out value is set to 1.0, the default setting, 

the value displayed on the main screen and stored in 

maximum speed, is true rpm of the shaft gear or flywheel 

that the rpm sensor is hooked up to. In order to program 

the unit to display speed in mph, a conversion factor is 

needed. Following are two methods of determining the 

conversion factor.

Method A

•  Mark the clutch bell that the sensor is reading from 

with a small reference mark. A marker works well.

•  Set the car next to a ruler and at 0” then roll the car 

forward by hand, counting each revolution of the 

reference mark. At exactly 10 revolutions stop the 

car. 

•  Measure the exact distance that the car traveled in 

ten revolutions and divide this distance by 10 (e.g. 

12.0” divided by 10 = 1.20”). 

•  Adjust the Roll Out value until 1.20 appears on the 

screen. Now all the rpm related functions will be 

displayed in mph or km/h. 

Method B

For this method you either need to know the internal gear 

ratio (normally provided in the vehicle’s manual) or be 

able to calculate the ratio via the number of teeth on the 

gears. It is also necessary to calculate the circumference 

(distance around) the tire. Once the internal ratio is 

known, and the circumference in inches has been 

determined, simply divide the circumference by the 

internal ratio and use this value as the conversion. 

To calculate circumference—multiply 3.14 x the tire’s 

diameter in inches.

To calculate internal gear ratio—divide the larger gear 

by the small gear. With multiple gear transmissions, it is 

necessary to multiply each of the larger to smaller gear 

reduction ratios to arrive at the final ratio.

Note

: The Telemetry screen displays the 

maximum recorded speed from the point 

that the receiver was turned on. To reset the 

maximum recorded speed, it is necessary to 

turn off the receiver, then back on.
