Hi guys im looking to get a faster motor for my hotshot.

i want a tamiya motor and to keep my ESC (TEU 104)

car is fully ballraced.

is there a big difference in top speed and acceleration over the standard silver can with the following motors?

also is run time reduced by a lot?

1. GT tuned

2.sports tuned

3.super stock BZ

4.super stock TZ - RZ

thanks for any advice as it will help me pick one.

cheers Karl

Yes, there will be a speed increase over standard silver can with all of those motors.

I run mostly onroad, and have tried the sports tuned, and Super Stock RZ. Of the 2 the Super Stock RZ is fastest, and I do run it with a TEU101BK, but I have a heatsink on it, and the motor.

Why not give the sports tuned a try. You'll notice the difference, runtimes should be very similar, and they're cheap. If it's still not fast enough, go brushless!

I've found that you don't necessarily need to reduce pinion size with the GT Tuned motor. Do use a steel pinion but if you run the same number of teeth as what you were running with the silver can you get a good measure of extra speed and torque and only a small decrease in run time and efficiency.

You will definately have to gear down (smaller pinion) if you choose a Super Stock motor. These are quite a bit faster which is great but you will notice decreased run time as they draw quite a bit more current.

Tamiya are soon to release some new Hop Up motors too, so it might be worth waiting for these. The new Torque Tuned and UGT Tuned motors look like they might be a good option. Good Luck.

[FLEXUS]

Alright Skottoman & Thommo

thanks for the advice guys.

am i right in thinking the GT tuned is faster than the sports tuned?

i was thinking of getting one of the above as they are recommended for the TEU 104.

i take it the super stock motors are much faster still which does appeal.

i,ve only ever owned standard motors so i have no idea how much faster the hop up motors make them.

cheers Karl

[Skottoman]

I have no experience with the GT tuned, or the Hotshot, but I can tell you, you will notice a difference with something other than a silvercan motor. Not like brushless difference, but more speed and power. It's one of the fun parts of the hobby, trying new things and seeing how they work!
Cheers,

I see that the new Super Hotshot actually comes with a GT Tuned. Some feedback from other members on how this goes would be helpful.

I've always opted for the GT Tuned over the Sport Tuned due to it having quite a bit more torque, open endbell and only a few dollars more.

I use a TZ Super Stock in my Egress and yeah the Super Stock motors are quite a bit quicker. I'm running this through a TEU104BK speedy and no worries as yet.

I have no problems running the GT tuned in my old supershot with the TEU 104BK .Thommo has seen this run & it went fine .

Hi Thommo

a fellow member on here has just built a new superhotshot and his bro a hotshot and both used the same pinion.

im waiting for them to have a drag race so i can get an idea of the acceleration and top speed difference between them.

nothing like a real world drag race.

I have no problems running the GT tuned in my old supershot with the TEU 104BK .Thommo has seen this run & it went fine .

hi Matman

the GT tuned is recommended for use in the TEU104 specs.
do you find this motor a lot quicker than a silvercan?

cheers again guys for the advice

Karl

[FLEXUS]

Well here is the race video... both new stock super hot shot and hot shot drag racing racing


Both running stock kit motors and 15t pinion gear both have a 6 cell NIMH 3900GP battery pack
Tamiya GT tuned motor is not much faster not worth $40.00 get a duratrax photon speed 2 20 turn motor for $11.00 and it will blow it away for a 1/4 the cost of the GT tuned motor!!

Hi guys

after seeing the results of the above drag race im going to buy a superstock BZ motor.

if running mainly on short grass using TEU104 ESC what size pinion should i use?

motor specs advise to Use within 9:1~11:1 gear ratio(how do i work this out?)

can anybody recommend a hardened steel pinion?

im currently running a 15t.

cheers Karl

Towerhobbies has Robinson Racing pinions. They are made of steel and they are metric (0.6 module) just like the tamiya gears.

The Hotshot however is a 0.8 module pinion gear, not 0.6 module. 32dp is a suitable replacement for a 0.8 module.

Part Number RRP0150 (USA - Robinson Racing); or ARW3200-15 (UK - RW Racing)

hi Mark/Chris

thanks for the recommendation i,ll look into ordering a steel 13t pinion when i order my superstock BZ.

Not sure what to do about getting a new ESC for the BZ as some people have ran theirs with no probs on the 104 although it is out of spec.

would the ESC just cut out till it cools or would it cause lasting damage to it and the motor/receiver?

cheers Karl

[wolfdogstinkus]

So how does the super stock bz motor compare to the likes of a 9T ezrun system?

I know the super stock runs at 26,500rpm with no load at 7.2V, and the ezrun is 4300kv so 30,960 but would you notice this on the car without any speed test equipment?, and how would the torque compare?

I might have to get one and test it but it looks like it could be a good deal as it's now less than half the price of an ezrun system and it will run with the standard tamiya ESC.

[94eg!]

...would the ESC just cut out till it cools or would it cause lasting damage to it and the motor/receiver?

cheers Karl

Yes it would cut out till it cools off. No big deal. It's called thermal overload protection.

Hi guys

Does anybody have any info/specs for this new tamiya motor?

http://www.modelspor...products/369339

will it run on the TEU 104 BK?

how fast will it be compared to say the sports tuned/GT tuned and superstocks?

cheers Karl

[wolfdogstinkus]

Yes it will work with the TEU-104BK, doesn't seem much faster than a silver can though

The Tamiya UGT Tuned Motor 24T features performance enhancements above stock silver can motors for faster acceleration and higher top speeds. This motor will work with the stock TEU-101BK speed controller

54391 UGT-Tuned Motor (24T)

• This is a tuned motor designed for use with electric R/C cars.
• Motor brush (standard type) replacement and the use of commutator cleaning brushes are possible to ensure motor performance.
• Motor can and end bell come in a stylish black color.
• The end bell features a heatsink design and incorporates heatsink brush holders.
• Comes with a detachable inboard capacitor.
• May be used in Tamiya official races.
• Input Voltage: 6.6-7.2V. RPM: 19,400 (7.2V). Torque: 49mN.m (7.2V).

Hi mate

thanks for the info,the specs look similar the GT tuned motor.

I,ll have to buy a superstock BZ and change the ESC to suit

cheers

[wolfdogstinkus]

Isn't the super stock BZ a 23T?, so it should run on the tamiya esc?

[Thommo]

Only change the ESC if you must but I can't see you having any trouble with the 104 as long as you use the smaller pinion.

[matman]

Has anyone used the TEU-105 yet ? & if so is it better ?.

[FLEXUS]

Isn't the super stock BZ a 23T?, so it should run on the tamiya esc?

Hi wolfie

yeah the super stock BZ/TZ/RZ are all 23 turn motors although i,ve read they draw more current than the sports tuned which is also 23t.

tamiya recommend the TEU 302 for the superstocks.

the TEU 104 BK is rated for the sports tuned and motors over 25t.

i,ve read on here people have ran them fine on the 104 and others have had problems with overloading the ESC.

i think it depends on the surface you run plus the car type,driving style and even the ESC itself.

Hi Thommo

Im gonna order the motor and a steel 13t pinion tomoz and i,ll give it a go.

I run mainly in my garden which is short grass and not too big so i,ll be on and off full throttle which i,ve read is worse for overloading the ESC.

i,ll keep an eye on the ESC temp so if it cuts out i,ll buy a suitable ESC.

cheers Karl

p.s the silver can got boring very quickly even in a smallish garden.

[GregM]

Has anyone used the TEU-105 yet ? & if so is it better ?.

Not used yet, but it's specs are apparently similar to the TEU-104BK. The TEU-105 has BEC, the TEU-104 hasn't. The 105 is mostly used in Tamiya's recent RTRs, as they come with 2.4G radio gear.

Compact forward/reverse ESC for electric R/C cars. Reverse function can be disabled
Compatible with LF batteries and includes a battery cutoff function to prevent over discharging
Features heat and over current protection functions with LED indicator
Equipped with aluminum heat-sink
BEC system included
Compatible with receivers from Tamiya and other manufacturers
Max. continuous current (FET spec): 60A
Input voltage: 6.6-7.2V
Compatible motor: Sport-Tuned Motor, motors over 25 turns
Receiver output: 6V/1A (BEC)

Thanks for that FLEXUS
I use a 19T motor with my TEU 104BK, I have used it in a pumpkin, a blitzer beetle, the sand rover and an M04L and never had any problems but maybe I got lucky with my ESC or the motor doesn't draw much current. It's a Peak Racing Raven SV2 motor. It's currently in the blitzer beetle and will make it wheelie but only when going from reverse to forwards. (Which I know is bad for the gearbox.)

Hi guys

my new SuperStock BZ motor and 13t steel pinion has arrived.

just had a look at the instructions and i,ve got a couple of questions.

it mentions the rotation direction CCW when viewed from the pinion end.
If i fit the motor then set the ESC and TX to forward and reverse as normal will this ensure the correct rotation?

also im goin to buy a set of spare brushes and a commutator cleaning brush set.
how often do you clean the commutator and change the brushes?(instructions say check brushes after 5-10 battery packs)

is there any method to run the motor in or am i ok to plug in and go?

cheers Karl

P.s it mentions to replace plastic bearings with ball bearings i take it this means all the bearings in the car?

[TA-Mark]

It's not possible to fit the motor in there any other way to change the rotation direction of the motor in relation to the direction the model travels. The reason the instructions mention the direction of rotation is due to the high amount of advance in the motor timing. You will certainly notice it if the motor is spinning the wrong way, just the same as you will notice that driving in reverse has reduced speed and power if it's fitted correctly.

Some models with two motors have one motor rotating CW and the other is rotating CCW. One of the motors in this situation would need to be retimed for the 23T BZ to suitable.

also im goin to buy a set of spare brushes and a commutator cleaning brush set.
how often do you clean the commutator and change the brushes?(instructions say check brushes after 5-10 battery packs)

Check them every 5 to 10 runs as the instructions say. More often when running in dusty or dirty conditions, less often when running in clean areas. If you use the included foam cover it's pretty obvious when things around the end bell are dirty.

P.s it mentions to replace plastic bearings with ball bearings i take it this means all the bearings in the car?

Don't run this motor with plastic bushings. Fit a complete bearing kit in the chassis. There is a high chance the extra rpm of this motor will melt the plastic bushings.

I wouldn't run a model even on the silvercan kit motor without fitting full bearings. The plastic bushings wear the metal shafts as well as the bush when they are run, and when you do finally fit bearings they are a loose fit on the shaft. Plastic bushings should be considered as shaft supports for shelf models only.
