Test the current draw at stall, not under load. The 57 Amps that I quoted is from the Mabuchi spec sheet on the RS540SH. Rated as such to cover the lowest common denominator, say a 5 year old who might try to power the motor while preventing the wheels from spinning. You and I wouldn't do it, but a child might. I know I've seen my kids do it with powered toys when they were younger. Rating the spec of the ESC above stall current draw dramatically reduces warranty returns, ie: you void your warranty if you fit a motor of lower turn than tamiya specify, even though the ESC will still power it.

Under 'normal' running conditions, and 'normal' usage, the Tamiya basic ESCs will happily power motors as low as 20 turn like the other manufacturers of 60Amp ESCs claim. They will not however live very long if you do as the 5 year old I previously mentioned does and prevent the wheels from turning while powering on.

The TEU101 is 100% power both forward and brake/reverse. The TEU104 is 100% forward, 50% reverse/brake power like you say. Otherwise the two are the same spec besides the LiFE 5.0v cuttoff in the TEU104.

One more thing to note. If you're using Ni-MH or Ni-Cd cell then the pack cannot supply 60Amps to the ESC even if the current draw from the motor is higher. Discharge rates of Ni-MH/Ni-Cd cells are not very high compared to modern Lithium based cells.

Well I don't hold my cars from rolling and floor them so i have no problems ...like you said maybe if you have kids running your cars but i don't so i am good to go and the duratrax photon speed two 20 turn motor for $11.00 is a gopod mod to make your car faster for the least $ possible... my esc's are doing fine on them.
And the funny thing guy's are worring about blowing there esc and buying these expensive high turn tamiya motors even if your stock esc blew wich it won't you can buy a new one on e-bay for $29.00 and that's still probably less money buying the 20 turn motor and a new esc than just buying the 25 turn tamiya hop up motor!

As most of above said, great colour combo's on both cars. I usually just go for box art, but they look awesome

Max. Continuous Current (FET spec): Forward 60A
Output: Forward 100%, Reverse 50%
Input Voltage: 6.6 - 7.2V
Compatible Motor: R/C car Tamiya Sport Tuned motors or motors more
than 25T
Driving Frequency: 1kHz
Output Voltage for Receiver: 6.6 - 7.2V
Dimensions: 1.6 x 1.4 x 0.59" (39.4 x 36.5 x 15mm)
Weight: 1.6oz (47g)

hi Shen/TA-Mark are these specs for a TEU 104?

how come it says compatible motor tamiya sport tuned(are these 23 turn?)

OR motors MORE than 25 turns?

does these mean it can OFFICIALLY run 23 turn motors eg BZ TZ or only 25 and above?

cheers Karl

You can get some comparison between the motors here. ===> Tamiya motors
GT Tuned has more torque...

Nothing like a real world test though.

still waiting.

Hi that's straight from tower hobbies site take a look and search tamiya esc they show the specs... like i stated the tamiya esc will run much lower turn motors then the 25 turn.

I am running these 20 turn motors in 4 or more of my tamiyas and i have no problems at all.

Well have to drag race em and see.

Hi Shen

have you had the supershot v hotshot drag race yet mate?

cheers Karl

[shenlonco]

It's raining here all the time we havent got a chance to race them yet everytime we can it happens to be raining!!

alright Shen sounds like you live in Manchester UK.

although this week summer appears to have finally arrived.

hi Shen has it stopped raining yet?

[shenlonco]

On and off Stopped but we could not get together to run them and now it's been humid and nearly 90Degrees!!
Don't worry i will post up the results or maybe even a video of the drag race when we get around to do it.

[shenlonco]

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 Shen

nice one for posting the drag race.

yeah looks like there,s not a massive acceleration and speed difference over the silver can.

i,ll probably end up getting a 23t superstock BZ as i mostly run in my back garden on short grass.

dont really want something too fast(garden size) although i do want a decent increase and the GT tuned as you say for the money does,nt offer much.

cheers Karl

[chriss76]

Nice movie, supprised about the lack of difference between the stock and GT tuned motor, I`ve got a RZ and dirt tuned for mine, will prob go with the RZ due to the nice red anodizing on it.

[shenlonco]

thanks guy's like i said for the $ you can get alot faster motors out there...when mine goes i am for sure not buying another GT tuned that's for sure.

alright Chris my fellow homeboy.

have you built and ran any of your vast collection yet?

which model is the RZ in/goin in and what ESC and pinion size will you/have use?

cheers Karl

[chriss76]

Hi Karl,

Not built a single one yet m8, too busy buying hop ups lol the RZ is going in the hotshot and as far as i`m aware the stock esc should handle it.
As for pinion size i`m not really sure, Once I find out i`ll order the hard coated ones from stella.
Soon as I have the cash I`ll get another hotshot so I can build one lol.
And besides 6 is not a fast collection compared to the likes of percymon lol
