IMPORTANT INFORMATION
THANK YOU FOR PURCHASING THE MRT MX PRO SPEED CONTROLLER. WE BELIEVE IT
IS ASUPERIOR PRODUCT WITH UNEQUALLED SPECIFICATION AND PERFORMANCE IN
THE SMALLEST SIZE. IT HAS BEEN DESIGNED AND MANUFACTURED TO THE HIGHEST
STANDARDS. OUR WARRANTY COVERS YOUR MX AGAINST MANUFACTURING DEFECTS
HOWEVER THE MX
REVERSE OR MIS-CONNECTION OF LEADS (THE MX CAN DETECT AND RECORD THIS)
RUNNING THE MX WITHOUT ASUITABLE DAMAGE CAUSED BY
SOLDERING, MIS-USE OR TAMPERING. DAMAGE CAUSED BY CRASHES OR BY NORMAL
WEAR AND TEAR DURING OPERATION AND USE OF THE MX PRO SPEED CONTROLLER.
*WARRANTY CLAIMS WILL ONLY BE ACCEPTED IF ACCOMPANIED BY THE ORIGINAL *
*SALES RECEIPT WITH ACOMPLETED MRT MX SPEED CONTROL WARRANTY FORM. *
(OTHERWISE THE MX NON-WARRANTY RETURNS REPAIR/SERVICING FORM IS USED)
IF THE RECEIVER LEAD IS REPLACED THE CONNECTIONS MUST BE RESEALED WITH
SILICONE SEALANT TO ENSURE FULL WATERPROOF OPERATION IS MAINTAINED.
WARRANTY IS INVALIDATED BY ANY OF THE FOLLOWING:
SCHOTTKY DIODE. ANY
THE MX PRO MUST BE CONNECTED ACCORDING TO THE WIRING DIAGRAM BEFORE
PROCEEDING. PLEASE TAKE CARE THAT ALL EQUIPMENT IS CONNECTED CORRECTLY
AS ANY MIS-CONNECTION MAY DAMAGE THE MX OR EQUIPMENT CONNECTED TO IT.
(NOTE: BEEPS WILL NOT BE HEARD UNLESS AMOTOR IS CONNECTED TO YOUR MX)
BEFORE YOU USE YOUR MX YOU MUST READ THE INSTRUCTIONS CAREFULLY
&REFER TO MX WIRING DIAGRAM TO BE SURE CONNECTIONS ARE CORRECT SETTING MX PRO TO ATRANSMITTER
MX PRO POWER PROFILES
If using an advanced type transmitter, check that it's set to 'basic' operation of the throttle channel
ie. with full travel (end point adjust) and no exponential, also transmitter trim &sub trim (if fitted)
is set at neutral position. If unsure check the transmitter manual. Agood way to check is if aservo
is connected to receiver channel 2it would have full movement with equal travel in both directions
(from centre). Abasic type transmitter should have the throttle trim centred. Once the transmitter
has been set to your MX Pro the channel 2servo reversing switch (if fitted) should not be moved.
1. Switch the transmitter on. Hold down the MX 'set' button and then switch MX on. If no MX 'on/off'
switch is fitted, proceed by connecting the MX to arace battery which will then switch the MX on.
2. After 4seconds the MX will make abeep, the 'neutral' position has now been set. The LED will be
on to show that the 'full power' position is now ready to be set.
3. Move the throttle control to the position 'full throttle' is to be set at (usually full travel end point).
Press and release the MX 'set' button to store the 'full throttle' position. The MX will beep and the
LED will flash to show that the 'full brake' position is now ready to be set.
4. Move the throttle control to the position 'full brake' is to be set at (usually full travel end point).
Press and release the MX 'set' button to store the 'full brake' position.
Radio set-up is now complete. With the throttle control in 'neutral' position, the MX LED will now be
on dim. Moving the transmitter throttle control should now operate the motor and brakes with the
power profile and brake minimum value as set on the MX (1 to 6). When the MX is at full power the
LED will be on bright, and when the MX is at full brakes the LED will be showing bright flashing.
Note: during radio set-up if any error is made ie. setting 'full power' at 'neutral' the LED will display
afast bright flash and afast-beep audible 'error' warning will also be heard.
The MX has 6throttle power profiles. Profiles 1, 3and 5are fixed 2.5KHz frequency with apunchy,
linear and smooth response respectively. Profiles 2, 4and 6are DualActive with avariable drive
frequency (VDF) and apunchy, linear and smooth response respectively.
The response characteristics for each DualActive profile gives athrottle curve plus drive frequency
'mapping' to maintain the maximum MX performance across the entire throttle range. The precise
frequency of each DualActive profile is continuously adjusted to respond to the throttle input along
with the motors varying power requirements due to changing track conditions. The advanced power
programming of the MX DualActive profiles confirms it as the Ultimate Competition ESC.
Note: most often the performance of low power motors (e.g. 27 turn stock) is best with profiles 1 or
2, medium power motors with profiles 3or 4(e.g. 19 turn) and high power (modified) with profiles
5or 6. Depending on the track layout, car type, motor type/wind, gearing etc, it may be found that
using different profiles to the ones recommended above can sometimes give better performance.
To check the currently set power profile, turn on the MX then press and hold the set button for 2
seconds, then release. The LED will flash brightly showing the currently set power profile as in the
table below. To change the power profile press and release the set button whilst the power profile
is displayed, repeat until the correct profile is selected. Finally turn off the MX to store the setting.
