The gears wouldn't last dry but would handle the power easily with some Teflon gel grease I got from radio Shack.
Grease would be too heavy in this case though so something like a Heavy-duty spray silicone would be a better choice. It is very light but is very slippery and is designed to lubricate plastic and such. Even a Teflon dry film lubricant would be excellent.
If your track is dusty and are worried about grit getting into your gear box, just smear a very light film of any type of grease between the diff case halves, bearing saddles and anywhere dirt can get in through, before you put them together. This should seal the dust out.




Yes, very important!

On a side note, if you did happen to accidently set the backlash too tight, here is where some sort of lube would be beneficial. Setting backlash should only be done with dry gears however.
I'm going to try adding grease between the diff halves and I'll try that Silicone spray. It sounds like good advice to me. I haven't ran shaft in a long time, been running belt so I could use all the help I can get.
I'm running 17.5 with a Tekin so I'm pushing the gears to the limit, the car so far is fantastic. I like it more than my TA05 that I've ran for years.That instant power out of the corners is amazing, and going into the corners I catch up with the belt drives real fast. Now all this car needs is a good driver!

You can also use Associated "Stealth" diff lube if you have some handy. It's what Associated recommends to use on the TC3/4 diff gears. I guess any other ball diff lube would work as well.

To me, lightly lubing the gears affords you alot more time between maintenance and/or replacement. Also, you would save the screw holes from too much wear and tear from all the screwing in and out as it already got a workout when you was setting the gear backlash.


I was really looking foward to running my brand new TB03 but I decided i'm going to sell it soon cause I have too many cars. It's still "plastic" anyways so it's a long ways from what I want it to be and it would cost a bunch just to bring it up to the "R" level.

A fellow racer had lot's of success in 17.5 with his self made "R" and boy it had some squirt in the infield. You would know he was coming when you heard the "whirrrrr, whirrrrr" sound. He did run his gears dry so I guess that's where the whirrring sound came from.

TB03 is getting cheap so i think a new version of tb03 is coming out or even a tb04. YAY

But for GT3 (silver can), the arrival of the TB03 renews the argument. I look forward to next season's TCS series to see how it shakes out. It should be fun! I love the new body and have wanted to try a shaft drive car, but the TB02 was just too dated compared to the TA05. Not anymore.
Both good but if you drive only on the track (TA05 sucks on the road, parking lot etc due to rocks in belt) get a TA05, want a mix of both, get TB03. Apparantly Tamiya says that the TB03 has almost no torque steer due to the TB EVO Drivetrain. I am getting a TB03 for the reasons is stated just now but i want to know if it can handle my brushless ezrun 9t and hobbywing 12T on a 20C Lipo 7.4V battery. I hate it when i strip my spurs in 3 weeks but i still want the tb03. Can you Help? Thanks

has anyone tried the light wt. reversable SHORT suspension arms on their tb03? tam53928. I bought the set of four thinking that was what was on the car and BAM the stock arms are about 1.5-2mm longer. Using the short arms i think I will have to use the "C" mounts up front like the 416 does. The "A" mounts on the tb03 are too narrow to use with the short arms. anyone here play with this mod? thanks.
