MX PRO BRAKE MINIMUM SETTINGS
MX LAUNCH CONTROL
MX INTERNAL POWER PROTECTION
MX PRO TECHNICAL SPECIFICATIONS
The MX has 6brake minimum settings. Setting 1is the minimum brakes and settings 2, 3, 4, 5 & 6
increase the minimum braking “strength”. Setting 1gives the most progressive braking whilst 6
gives the most aggressive. Note: the maximum braking available is engaged when the throttle
control is in the full brake position. The “strength” of the brakes is dependent on the motor type
and motor wind being used, generally 'hot' motors will give the strongest brakes.
To check the current brake minimum setting turn on the MX, then press and hold the set button for
4seconds, then release. The LED will flash dimly showing the currently set brake minimum setting,
see the table below. To change the brake setting press and release the set button whilst the MX is
displaying the currently set brake minimum value. Once set turn off the MX to store the setting.
The MX has “launch control” available which is very useful to give an “assisted” start line response.
From the race start launch control will provide maximum power and acceleration until full throttle
is reached. After full throttle has been reached and held for 1second, the throttle response will go
back to the profile that has been set. Note: use launch control wisely and take care as it's very fast!
To set launch control, hold the transmitter throttle control in the full brake position for 4seconds,
launch control will then be active. Note: the MX will also make a'beep' to help with bench testing.
The MX has in-built protection to help avoid damage. If the MX detects over-temperature due to a
fault, extreme overload running or using without aschottky diode it will run but only very slowly.
You MUST stop and check it immediately. If the MX gets hot caused by afault or being subjected
to extreme operating conditions etc the user may experience the in-built protection continuously.
If any prolonged abnormal operation is experienced the MX should NOT be used as damage may
result. Stop using the MX until either the fault is found or it has been returned to MRT for testing.

MX PRO OPTIONS &USER NOTES
The MX set-up button may be 'unplugged' if required, this is useful when soldering to connections
or when the button is to be situated in an external position. An optional extension set-up button
lead is available as MRT option part no. 9007 (also areplacement set-up button MRT part no. 9006)
The MX may be re-reprogrammed via data port (by MRT) if firmware profile upgrades are required.
The MX has abuilt-in heatsink under its MX label. Upgrades for future include optional MX heatsink
and MX high-flo micro fan unit for direct fitting, these options will help in extreme heat conditions.
It is recommended that MX Pro power plugs (if fitted) and leads/connectors are replaced following
long periods of use, as unreliable/worn connections could result in impaired operation or damage.

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:

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.
