Tamiya F104 Pro!
#7651

Yes there is...
It will smoothen the diff big time and adjustment has a better feeling to it.
Don't forget if you use the one piece trustbearing to put the spring rings like this--> )(
I have been running it since i have the F104W Pro and love it(use the same setup on my F103).
On my F103 that i have been running all year, i didn't even had to rebuild it.
It is still smooth as a baby bottum

I know this has been answered many times before, but I'll ask it again because it's too hard to search through all the pages of this forum...
Inside the diff, is there any performance advantage if I replace the bearing with a thrust bearing? I never really took it to heart because it's hard to find thrust bearings in our country. But I just found out that I had one sitting inside my toolbox all these years. Sheesh.

I am just afraid that when something breaks on race... I just ended... there's allways seller with Tamyia parts, but Exotek? zero chance....
P.S: thanks guys, i will look for Tekin and new Speed Passion (Reventon seriess)
P.S: I am running on carpet just now, thanks for advice for top plate :-)

BTW For the carpet I like stiffer settings with sharp response that's why long top deck. I can recommend laid down servo setup, one piece thrust bearing in differential, short lipo or X1 upgrade. All these upgrades work very well for me this carpet season.

There are bent front upper arms, demaged spur gears (outdoors), maybe broken rear axles, most unsafe parts are really Tamiya parts and it takes 7-9 days to deliver small parts from US to CZ.

hmm, i do not have short lipo :-( I have only lower one, so...
EDIT: I also wanted to ask... Our best F1 driver (Drives F104W) suggest me to remove F104 Pro's front axle and use the wolf's one (it's wider) and I also noticed that his car can drive much faster in turnings without sliding out... my F1 just can't handle the speed... (or I am bad with throttle...).
Is it usefull to change the front axle?

Here is the one piece thrust bearing.
and as for the front axle, The F104w is wider than the F104 pro 200mm vs 180mm. You can change to the wider front end, but you would also have to change to the tires and wheels for the F103/F104W. There is a new product from RSector that will widen the front and rear ends without having to buy new tires. It will push the Pro out to 190mm which should help a lot.

For ETS races- what does "we will provide our own 4100 mAh shorty packs" mean? Does this mean I would have to buy their LiPOs in order to compete? And also, F104W is not allowed since it is not 180 mm (even though it says all F104s are good)? Sorry for these noob questions, but I'm new to F1 and I'd like to get one in order to compete in ETS

The F104w is not allowed, only 180mm wide tamiya or hpi f1 cars. If you have a f104w you can get the f104 front arms to make it 180mm. You also have to use the Ride tires.

yes, you will have to use the shorty lipo, you can get it at Toni sport, with some other ETS stuff: http://www.fast-webshop.com/tonispor...1-ETS-products

Does tamiya 53259 3.5mm offset uprites work on the f104 front end?

Oh, I am already using that 1 Piece Ball Thrust Bearing.... so it's fine :-)
anyway, I used only one tires for entire carpet season... they were good on every carpet I was driving on... (two carpets, both from same company, so...) but they are running out now... I would buy new tires for carpet anyway

Absolutely, and this is my choice for running on asphalt/low grip surfaces.
Calms the steering down very noticeably.
Warning, when using the 3.5 uprights, replace the axle screws cuz they are very soft and will break at a critical time (qualifier at TCS) and the wheel is gone.
I now CA the axle into the spindle and replace the soft screw with a black oxide socket head cap screw and red Loctite. Yeh, permanent deal but I still run the original modded pieces on each of my F1 cars, 104 and 103.
When traction is high, I like the inline stock spindles for increased steering response tho.

Hello guys, so today I decided to degrease and rebuild the diff on my X1 since from the beginning it felt very dry and gritty. I degreased everything and rebuilt it using 30k oil since I thought maybe it was my grease. It continued the same way so I proceeded and degreased it again, sanded the plates with 400 grit sand paper and built it with mobil1 synthetic grease. It felt way better but still feels dry and gritty very different as how the ball diff on my xray T3 feels. What could it be? Maybe thrust bearing?

I'd try that first or if you wanna take all the guess work out do the thrust bearing too. Still cheap.
When you're assembling, work the diff halves, rotating/working them as to not flat spot balls or dent rings. Make the spur very hard to turn by hand while gripping both wheels. I'm liking the Mobil 1 grease on diff and thrust also. Super smooth.
