    When we talk about speed, the first thing come up with our mind is motor, Yep, that is the right concept, also it’s the most easy way and direct way to show the speed. Tamiya mini 4wd has a lot of different motor, some are high torque, some are high speed, some are single shaft, some are double shaft, find out the right motor for your car is very importan.

    Atomic-Tuned:

    Single shaft :

                                                            Double shaft:

    December 17, 2005

         Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.3-1.8
    RPM(r/min) – 13700-16200
    Current (A) – 1.5-1.9

      July 4, 2015

    Balance of torque and top speed makes this motor suited to use on tracks combining numerous straights and curves.
    Features a black end bell.
    Input voltage: 2.4-3.0V
    Torque at recommended load: 1.6-1.8mN-m
    RPM: 12,300-14,500
    Current consumption: 1.5-1.7A
    Compatible with Mini 4WD PRO cars only.
    Pinion gears sold separately.

    The Atomic-Tuned Motor is a balance-type motor with the perfomance characteristic that is similar to the Hyper Mini Motor. It sits between the speed-focused Rev-Tuned Motor and the acceleration-focused Torque-Tuned Motor.

    While both the power and torque of the motor are a little bit inferior than the aforementioned tuned motors, it is suitable for race tracks that requires both power and torque performance if the use of Hyper-Dash Motor is impossible due to course layout.

    Only the original Atomic-Tuned Motor has the deep gray endbell cap, while the others has black endbell caps. All models has the silver metal housings. Only the original Atomic-Tuned Motor PRO came with the brass pinion gears attached.

    Hyper-Dash:

    Single shaft:

    1999

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.5-2.0
    RPM(r/min) – 12000-14300
    Current (A) – 1.3-1.7

     

    2014

                  Input voltage: 2.4-3.0V
    Torque at recommended load: 1.4-1.9mN-m
    RPM: 17,200-21,200
    Current consumption: 1.6-3.0A

     Double shaft:

     2005

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.4-1.9
    RPM(r/min) – 17200-21700
    Current (A) – 1.6-3.0

    Also TAMIYA JP will release limit edition for every Japan Cup.

    2014 JPC :     

    2015 JPC :     

    2016 JPC :     

    All revisions has the red endbell cap, and all but the first Hyper-Dash Motor has silver metal housing (HD1 has black housing instead).

    All Hyper-Dash Motors are performs better than Rev-Tuned Motor and Light-Dash Motor on revving but has medium torque perfomance compares to the torque-based motors. Both HD3 and HD PRO (made by SMC Motor) use carbon brushes instead of metal brushes, provides longer running life.

    All motors, except the original Hyper-Dash Motor, can be use in Tamiya official race tournaments. Since both HD1 and HD2 are discontinued. only HD3 and HD PRO can be use.

    Mach-Dash:

    2011

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.4-1.9
    RPM(r/min) – 17200-21700
    Current (A) – 1.6-3.0

    On the exterior, both versions has the red endbell cap and silver metal housing. Both motors are the speed-focused motors.

    The single-shaft version of the motor is powerful than the Hyper-Dash Motor at the time it released, but because of that, the motor has shorter running life and very power-hungry as the results.

    The double-shaft version is the more refined version of its single-shaft motor counterpart and behaves similar to that of Sprint Dash Motor, which explains why it can be use on official tournaments. It is also the only variant of Mach-Dash Motor that use silver carbon brushes.

    Because both motors has moderate torque, they are not suitable for race tracks that has very high acceleration requirement.

    Rev-Tuned:

    2015

    High-RPM motor with great top speed on straights. Suited to use with small diameter tires.
    Features a blue end bell.
    Input voltage: 2.4-3.0V
    Torque at recommended load: 1.2-1.5mN-m
    RPM: 13,400-15,200
    Current consumption: 1.6-2.0A
    Compatible with Mini 4WD cars.
    Pinion gears sold separately.

    2005

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.0-1.3
    RPM(r/min) – 14300-17400
    Current (A) – 1.6-2.0

    2015

    High-RPM motor offers great top speed on straights and is well suited to use with small diameter tires.
    Features a blue end bell.
    Input voltage: 2.4-3.0V
    Torque at recommended load: 1.2-1.5mN-m
    RPM: 13,200-14,900
    Current consumption: 1.5-1.8A
    Compatible with Mini 4WD PRO cars only.
    Pinion gears sold separately.

    As its name implies, it is a speed-focused motor and has higher power but lower torque when compare to Torque-Tuned Motor.

    The original version of the Rev-Tuned Motor has the Mini-F label as it was originally a upgrade parts for Mini-F. The second version changed the label to replace the word ‘Mini-F’ with ‘4WD’ (as in Mini 4WD). The current version has the word ‘4WD’ removed from the label and the empty space has been filled with the larger-size of the words ‘Rev-Tuned Motor’.

    The original Rev-Tuned Motor has the purple endbell cap, while the rest of the Rev-Tuned Motors has the blue endbell cap. Only the original Rev-Tuned Motor PRO came with the brass pinion gears attached.

    Due to its lower torque, it is not recommended to use it on Mini 4WD cars with large-diameter wheels and low-gear ratio.

    Torque-Tuned:

    2015

    Voltage(V) – 2.4 -3.0
    Torque (nM-m) – 1.5-2.0
    RPM(r/min) – 12000-13600
    Current (A) – 1.3-1.7

    2015

    High-torque motor features excellent acceleration and holds speed well on both curve and slope sections.
    Features an orange end bell.
    Input voltage: 2.4-3.0V
    Torque at recommended load: 1.7-2.1mN-m
    RPM: 12,200-14,400
    Current consumption: 1.7-2.0A
    Compatible with Mini 4WD PRO cars only.
    Pinion gears sold separately.

    As its name implies, it is a torque-focused motor and has higher torque but lower power when compare to Rev-Tuned Motor.

    The original version of the Torque-Tuned Motor has the Mini-F label as it was originally a upgrade parts for Mini-F. The second version changed the label to replace the word ‘Mini-F’ with ‘4WD’ (as in Mini 4WD). The current version has the word ‘4WD’ removed from the label and the empty space has been filled with the larger-size of the words ‘Torque-Tuned Motor’.

    All Torque-Tuned Motors has the neon-orange endbell cap and silver metal housing. Only the original Torque-Tuned Motor PRO came with the brass pinion gears attached.

    Plasma-Dash:

    1996

    Voltage(V) – 2.4 -3.0
    Torque (nM-m) – 1.4-1.9
    RPM(r/min) – 25000-28000
    Current (A) – 4.1-5.2

    The motor has the gray-color endbell cap and black-coated metal housing with the Tamiya motor sticker on it. Unique to this motor is the redesigned metal housing, which dissipates heats from inside the motor, resulted in prolonged running life of the motor despite its monsterous performance.

    It uses the carbon brushes, and is user-replaceable (with the Plasma Dash Brush Holder Set AO parts) without opening the motor first hand.

    The spec of the Plasma Dash Motor is higher than any Mini 4WD motors Tamiya ever released, not even the official-tournament-approved Sprint Dash Motor and Power Dash Motor can keep up.

    Along with Ultra Dash Motor and Jet-Dash Motor, it was banned from use in Tamiya official races due to its overwhelming performance.

    Touch Dash:

    March 11, 1998

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 2
    RPM(r/min) – 11000-15000
    Current (A) – 1.3

    The Touch Dash Motor sports the light green endbell cap and silver metal housing. Perfomance-wise; it is similar to the Torque-Tuned Motor.

    One unique trait of this motor is that it can switch on and off itself. The motor can be switched on by pushing the mini 4wd car forward, and will switch off if the motor is under extreme loads. (i.e. the Mini 4WD car is hitting a wall)

    Although the motor has been since discontinued, some Tamiya plastic models, such as the Nakajima Ki-84 Hayate airplane model, includes the motor as one of the components.

    Ultra Dash:

    1995
    2002 (R/C Mini 4WD re-release)

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.4-1.9
    RPM(r/min) – 24000-27500r
    Current (A) – 4.0-5.0

    The Ultra Dash Motor has the black endbell cap and silver-plated metal housing with the Tamiya label on it.

    The performance of the Ultra Dash Motor is somewhat similar to that of Jet-Dash Motor despite having the different OEM. It has 2g-cm less than the Jet-Dash Motor.

    Along with Jet-Dash Motor and Plasma-Dash Motor, it was banned from Tamiya official race tournaments due to its overwhelming performance.

    Sprint Dash:

    2002

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.3-1.8
    RPM(r/min) – 20700-27200
    Current (A) – 2.8-3.8

    The Sprint Dash Motor was a speed-focused motor, with the revving performance of 27,200rpm (20,700rpm on load) and the somewhat moderate torque of 19.4g-cm (formerly 14g-cm on the first revision). It has the second highest rev perfomance following the Plasma-Dash Motor and has the same torque characteristic of that of Ultra Dash Motor. It is the 2nd power-hungry motor following the Plasma-Dash Motor and as such, it can’t reaches its full potentials while using the normal alkaline batteries.

    The first version of the motor, released in 2002, has the white endbell cap and silver metal housing, and uses bronze brushes. The words ‘R/C Mini 4WD’ was printed on the sticker below the words ‘Sprint Dash’ and the Tamiya logo.

    Later versions uses the carbon brushes which prolonged the motor’s running life, and also increased overall performances. Torque performance of the motor has been increased from 14g-cm to 19.4g-cm with this revision. On the sticker, the word ‘R/C Mini 4WD’ were replaced with the words ‘Specially Tuned’.

    Due to its low torque, it is recommended to use it on Mini 4WD car with small-diameter wheel and high gear ratio set to archieve optimal performance.

    Light dash:

       

    2012

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.3-1.9
    RPM(r/min) – 14600-17800
    Current (A) – 1.5-2.2

    2009

    Voltage(V) – 2.4-3.0
    Torque (nM-m) – 1.3-1.9
    RPM(r/min) – 14600-17800
    Current (A) – 1.5-2.2

    Specifications This new motor for Mini 4WD machines has performance that strikes a good balance between the Hyper-Dash Motor PRO (Item 15375) and the Torque-Tuned Motor PRO(Item 15346). The Light-Dash Motor PRO now offers Mini 4WD drivers with another choice to power them to victory. Features The Light-Dash Motor PRO offers excellent efficiency and superb endurance. Requires installation of separately available 8T pinion gear, and maintenance of the counter and pinion gears. This motor is for top level Mini 4WD drivers. Can be used with any Mini 4WD PRO machines. Yellow end bell.
