Sport Tuned Motors In A Clod

[kaiser]

i have been hearing mixed opinions in regards to using two sport tuned motors in my clodbuster.

i'd like to have tamiya clibs opinion on the matter, because frankly you guys are the authority on all things tamiya and i trust the advice i get here.

so, have any of you used a pair of sport tuned motors in you clods? do they work correctly?

seems some memebers of other boards think that you can't run them in reverse rotation.

so what do you guys think?

i have a pair wating for me at home, but i'm not going to bother if it's been tried and it didn't work.

if it won't work do you think a pair of gt tuned motors will work?

thanks, i look foward to hearing your opinions.

This new ESC has been specifically designed for use with Tamiya's twin electric motor R/C vehicles to control up to two Sport-Tuned Motors....

*Compatible Chassis: Wild Dagger, Twin Detonator, TXT-1, Super Clodbuster...

Specs:

Compatible Motor: Up to 2 Sport Tuned Motors

Go nuts.

You have to post a video though. (it's somewhere in the small print)

Ran 2 in my Twin Detonator and they are so much fun. As I've said in another post, the Sport Tuned is just a zooped up silver can, different brushes and magnets and it happily spins forward and reverse without any problems.

fantastic! the two guys who's clod advise i value!

does the twin det and related trucks run one in reverse also?

thanks gents.

Yep, the Detonator, Wild Dagger and Dual Hunter all share the same chassis and gearboxes. So the one sits in the front with the motor on the left running forward and in the rear the motor sit on the right and runs "Forward",..................... but in reverse. uHMMMM sound about right

Thanks for the compliment.

I put 2 Sport Tuneds in my Clod (powered through an Mtroniks RV11) and to be honest I was a little disappointed in the speed increase. In the Clods defence though they were second hand motors so could have been the far-east 27t versions...

[kaiser]

thanks again gents!

I'm sorry for digging up an old thread, but I'm very confused.....

I understand that the sports tuned motor is a 27 turn motor.

But is the motor advanced timed or not?

It seems that there are a lot of people out there who use sports tuned motors in colds or daggers/twin detonators/similars without ans problems.

Do they not realize that the back runs quicker than the front? Are they all wrong?

Or could it be that the sports tuned motor just has better magnets and quality without Bering timed?

[shenlonco]

I thought the sport motors had some timing to them?

Not 100% sure though.

[whahooo]

That was the Information i had too, but there are a lot of people who use them motors in 2 motor chassis anyways.

And i don`t speak of the TXT or Juggernaut, i think they use the Motors in the same directions.

There are also people on YouTube who use the sport tuned motors in dual motor chassis.

There are also members who opened the sport tuned motors in the past to see the turns and if they are advanced timed.

It would be awsome if one of the people who done that could ensure that they aren`t timed or that they are timed.

[beefmuffin]

I was under the impression they ran faster fwd than rev also. Otherwise I prob would have used them in my Twin Detonator chassis runner instead of a pair of matched F/R Kyosho Megas. Been a while tho... so, cobwebs.

[shenlonco]

you running the stock esc?

I know HPI has a 15 turn motor and a lot of guy's use those because they are not timed.

another choice is atomic RC makes brushed motors and they make 21 turn motors you will have to adjust it's timing to 0 on it's adjustable timing end bell.

[whahooo]

I'm running the stock Tamiya dual motor ESC.

Tamiya says that it could handle 2 sport tuned motors, but they do not mention in wich chassis.

2 timed motors in a TXT or a Juggernaut would not be a problem.

[beefmuffin]

Here's a nibble of info I dug up:

http://www.oople.com/forums/showpost.php?s=f7aee9f04f60aa65ae2a9580fe510c75&p=193190&postcount=6

There were two types of motors, the difference was that the 23 turn had no advance timing, the 27 turn has the timing advanced to get the extra speed out of it as well as different wire thickness. I believe all modern Sport Tuned motors are 27 turn.

[XV Pilot]

A good way of telling which kind you have is to hook it up to a battery and listen to the pitch of the sound made by the motor. Then swap the polarity and listen again. If it sounds the same, you have a zero-timed motor and you can run it in the front gearbox without a problem. However if the pitch changes with the polarity change, you have a motor with advanced timing which will run poorly in the front gearbox with reverse rotation.

[whahooo]

Ok, I'll risk it and purchase a couple of sport tuned motors from amazon (I think there they are the cheapest) and test the pitch of the sound.

If they are timed, I have some sparemotors for my other models.

For what I understand, there aren't any 23turn sport tuned motors, they are all 27 turn.

The question is only if they just have stronger magnets of if they are timed.

I'll test it and post my results!

[shenlonco]

you should be able to run the 21 turn atomic RC motors just have to set them to 0 timing.

[whahooo]

If I could run 21 turn motors I could run 23 turn super stock motors also.

But Tamiya says I should not operate hotter motors than the sport tuned with that ESC and I don't want to ignore that.

And a Clodbuster is a very heavy model with big wheels so i'll not risk that.

For me that topic is closed.

I'll wait for my sport tuned motors and test the pitch of the sound in both directions.

Thank you for all the input and help.

I'm very thankful.

[shenlonco]

I ran 2 twenty turn motors in my clodbuster on the stock ESC with no problems.......Tamiya highly underrates there ESC's I run 20 turn motors on all mine all the time.

If I could run 21 turn motors I could run 23 turn super stock motors also.

That`s good news!

May i kindly ask what 20turn motors you are running?

Because the super stock motors are pretty powerful 23 turners...

Some time ago i got an 18 turn motor from Absima called "thrust" the seller told me that thing will be plenty of fast in comparison to my 23 turn Cup machine (the Cupmachine was not remarkable faster than my standard silvercan).

I putted the 18 turn motor in to my Blazing Star (smallest pinion) and had a look..... ....i was a little bit disappointed.

So fudge it, i thought and putted in the 27 turn sport tuned motor in the car, because i knew with that motor i had better results in the past.

And behold... ....the result was not half bad, it was somehow accaptable.

So i sweared to myself, never ever buy a cheap motor - never again!

I made a bad expierience with a 23 turn Cup machine (cheap) and a bad expierience with the Absima motor (cheap).

The Money i wasted is worth a new Sport tuned Tamiya motor or even a used super stock one.

[shenlonco]

Hi I used 2 duratrax photon speed two motors but you need to bend the metal end tabs on the endbell and pull the cap out a bit and twist it and put the notch on it to the center spot so it has 0 timing because they are timed out of the box.

That`s good news!

I know the Carson Cup Machine motors. The distributor doesn't state any winds for them. My guess is they aren't 23 turns. I'd rather say they are 25 to 27 turns. They're just the typical fan equipped brushed cans, sold by so many other distributors under different names. They're usually cheap, lack torque, have moderate RPM advantage Vs. a RS-540 and are inefficient, thus building up heat. I wouldn't be surprised if the Photon motors are coming from the same OEM.

[whahooo]

I think the seller listed them as 23 turners, but I've learned to stay away from them.

Today I've tried the superstock bz motors with the quicrun wp 860 ESC and I've learned that this combo do not work, the ESC was quite warm after a one minute and the reverse gas was not working at all.

Tomorrow maybe I'll try the superstock bz motors with the tamiya dual motor ESC.

EDIT:

Silly me, i had my transmitter set too half throttle....

Now its set to full throttle and my Clod is a lot faster!

[shenlonco]

Found a nice motor and it has 0 timing.

[whahooo]

Today i've tried the sport tuned motor in both directions

The pitch of the sound in the rotationdirection is higher than against the rotationdirection.

Sadly i have no accurate tuner (for musicinstrumentes) at home, so i can't post the exact frequenzies.

But anyways, the motor is timed. For shure!
