I saw this TT-02 Belt Drive kit on AliEpress. It is inexpensive,  interesting or as Spock would call it "fascinating"!

Soooooo, i ordered one! I have built five tt-02 cars using tips I have found on this forum which from my first build made them all better than they would have been from just using the manual.

I have come up with a few things myself which I would like to share when time allows (like the motor air scoop accepts a 30mm fan and does very well to cool your motor when a fan is used ! Why Tamiya doesn't mention this is beyond me) ...more to come; but back to this belt thangy!

It looks to be of fairly good quality and since I am currently building a rally tt-02 and my first TT-02B i will try it in one or the other and report back.

Omg, my thoughts EXACTLY!!!! LIMIT!

Motor mounts exactly the same.

I have a couple HyperDrive belt kits for my RC-10 cars, makes for a smoother drive system BUT those kits came with other pinion and spur options.

It looks like the FDR of this kit would limit one to a pretty high turn motor and therefore maybe meant for 17.5t or 21.5t racing but would not be legal for use anyway. It was $8 shipped so i had to get one, see what its all about at least.

No manual, but its a straight forward install.

Here is the link for the one i got.

Not sure what is the point in this. Seems like a conversion for the sake of a conversion. If anything, it seems to limit the gearing options.

Having said that, I am so going to get one if I ever get the TT-02R I want to do for my budget rally build. 😁

Quick question, does it comes with any instructions? How are you supposed to mount the motor? In what position?

Got the AE link?

That a pretty tall gearing indeed. I guess you can experiment with various holes until the tension in the belt "feels right"?

CRAP! I am very sorry! I am a certified webmaster and ancient A+ guru, appeared in magazines having built show machines for Alienware, and installed intranets in Dubai but I canNOT land a post in a proper forum topic to save my life!

Im not being sarcastic,  I am sorry!

Thanks for the link, added to my watch list. Don't mind me, what I said was tongue in cheek, it does seem pointless to me, but at that price, I want to do it, just because I can! 😁

100% agreed! Just because its there gotta see whats up with it! Lol

I was looking at the SCX10 Belt system on amazon and I believe the pinion could be swapped for other size pinions using the scx10 kit. My buddy has the SCX10 kit so i can check pitch, i will also be checking my RC10 kit but I am almost positive it has a finer pitch than this tt02 kit.
