Sure enough, Tamiya makes a light weight version of the ring gears...

I will install the hop-up 6mm clamp-type aluminum hex.. as in all my other cars..

Haha clamp type hex...imagine that! Did you buy a pallet of them or what I wonder why they used the metal gear and heavy prop shaft I guess all in keeping with the theme of offroad type rally car, but the car is still light, like you say I doubt it would trash a regular plastic gearset. I have jumped the dark impact plenty without a slipper and haven't had a problem with it's gears. Plus I think tamiya has better grease for plastic gears (ceramic) than they do for metal (anti wear etc)

I love the 6mm clamp type hex.. Let's just say that I have enough to last me awhile...

Yeah, I think it is just the old school design. For my purpose, I am building a scale looking rally car, I doubt that it would matter that much. But a set of those lightweight plastic gear is only like $9 shipped, so I might just go for that. The carbon shaft is too expensive! (I wish it is around $15, I'd get it.. !)

We will see.. I guess I am just not sure if I want to hop it up w/ everything knowing that it will probably be used once or twice only and sit on the shelf.. but I guess that has never stopped me before..

Looks like there's a cheaper alternative! Tamiya makes an aluminum version of the center shaft! And it is much cheaper!!

I will probably just go for that!!

I bought a Tamiya BMW 320si WTCC 2006si, anyone knows if is possible to run this car with a 7.4v 10C 4000mAH lipo battery with stock parts.

Thanks

Is it a TB-01?! Can you post a pic?!

The battery itself does not determine the stress put on the drivetrain.. the other part of the equation is the motor / ESC, so it is hard to answer your question without knowing the other part of the setup that you plan to run!

Good luck!!

the reference is XB BMW 320si WTCC 2006 Team Germany (TT-01)

how cai i post a pic, sorry am new here

Lunchboxer

TT-01 is a different chassis compare to the TB-01. You might want to search for a TT-01 thread!!

Posting picture is easy, just click on post reply, and then you can attach pictures. I suggest you do a search on this topic as well.

Good luck!!

Sidewinder 5700kv will do the propulsion duty..

Using Castle Link and updated to the latest firmware..

S3010 will do the steering duty..

Got a couple of S3050 digital servos w/ metal gear, but I think I am going to save those for my DF-03 resurrection project..
