I don't think this thread may be as poplar as the other ones but here it its if you need tb03 help.

Mine has some upgrades, arta garayia shell, 8.5t ezrun 4000kv motor powered by 3s lipo.

Its a blast to drive and love the sound the shaft makes at high speed

Have you checked the balance of your center drive shaft? Roll it along the corner of a table to see if it wobbles or not.

Haddi Taha

so an uneven drive shaft makes cool noises? </p>

dragnse7en

It could make some noise but not always at first. It will definitely make noise when the imbalanced shaft prematurely wears out bearings and bevel gears.

Look for a noise that sounds like a wobble and then check the gearbox's bevel gears.

Haddi Taha

it only makes the noise at high speeds when driving, check out this video i found.

That's some really good driving Haddi. [8D]

Haddi Taha

thats not my video as i wrote, credit to the uploader. but yeah the driving from the that guy is pretty good.

Haddi Taha

i roled the centershaft as you said, no wobbling. Some say itts a characteristic of a shaft car with a smooth drivetrain.

Does your car sound anything like this? The AE TC4 is shaft-driven:

sounds similar but because he has twice the power and more so he's is louder. But the sounds seems to goabit once the tires have stop squelling and gain grip. Anway its pretty cool, it scares all the belt driven car drivers when they hearthe tbon the track

I still have all the kit's original universals, but I want to change out the rear blue aluminum ones with some stronger black steel ones. The rears are 44mm and the fronts are 46mm. I like to use some 48mm ones for both the front and rear, just like my older car, but I want to see how well these wear before I make that decision.

Did you already get #54147 TB03 Carbon Reinforced Lower Deck?

Haddi Taha

the cf deck has been ordered so its not on my to get list, wainting for it to come. I dont like the alloy rear lightweight swing shafts, bend to easily, so i am getting steel 44mm for front and back for the tb03.

By the way, if you were to remove the front cvd and drive your 4wd touring car so its 2wd is it going to be slower?</p>

dragnse7en

Yep. I tried 2WD once and the rear wheels had double duty with all the weight of the car instead of "half" its weight. It went the same speed but took longer to get as fast.

Haddi Taha

i did 2wd when my diff acted up and it was terrible, you can barely turn without spinning out, but 4wd i just amazing.

Haddi Taha

this car can take on trf416's and xray t3's if set up properly.

I heard a story from a friend with a tb03 who drove his tb among other cf belt cars and was very succesful. The track owner was impressed and bought a tb03. The track owner was so impressed he sold his xray t3 to get another tb03.

Many guys over at rctech are having good success with the chassis, several hopups are needed to get the car to perform that great.

Any updates on your TB03 Haddi?

Haddi Taha

I have got it running again 2 weeks ago, installed a 3s LIPO yesterday and it flies. The 4000kv motor is working well. I think it does 50mph which is enough for the meanwhile. I know have enough parts to build 2 more diffs but all the dff problems have now gone away [&amp;:].

Need more tires

If i can i will take a video when i go to play indoor soccer tonight in the parking lot.

dragnse7en

Good to hear about those diff problems gone now - good deal!

Haddi Taha

shoot i royally overgeared (like buy 3 0.6 metric gears, thats alot) so one of my motors soler for the wire melted off. Need to solder it back.

dragnse7en

yeowch!

Haddi Taha

The ezrun motors and esc are very tolerable to heat (under the right applications) it took me 12 months to smoke a 35amp esc geared 1.25 rollout. It went very hot but never quite.

What i like about ezruns is that the motor wires plugs always melt off before you damage your motor in my experience. I have now geared down from 1.25 rollout to around 1.05.

Gearing is so weird, some times you have to stick to 0.9-1.1 rollout and sometimes you can gear to the moon.</p>

dragnse7en

Sorry Haddi, you have totally lost me on your gear ratio numbers. Tonight I will start another article; finding your car's gear ratio and Final Drive Ratio, no matter what type of vehicle it is. Yes, there's a math formula for that. Stay tuned . . .

Haddi Taha

Cool I will be looking forward to that. I was taught to gear to 0.9-1.1 rollout and gear down or up according to heat build up.</p>
