My T bar does move side to side when the screw is not so tight, that means it's worn? I recall there are 2 different t bars Tamiya made?
I am using the stock foams, do you know what shore they are? I have a feeling the stock rears may have too little grip for the low grip asphalt I am driving on. I am also running Lipos. On this surface, even 4WD TCs rear can come loose sometimes, we run Sorex40r on TCs as the weather is quite hot. What tyres do you recommend for my F103, Zen? Or even should I go for TRG rubbers ($) in my application?
Thanks again for your help again!
Sorry for the late reply.
So with the "O" ring set up its a little better for you? You said it was a little dusty. Can you get rid of the dust? We have a leaf blower we use when it starts to get dusty.
Your "T" bar will move a little but it is hard to tell without the car in hand if its worn or not. But you can check the rear hole with the front hole. Usally the rear wears out and the front stays its normal size. See if the rear hole is bigger.
The optional Tamiya "T" bar is a little softer than the stock piece. It also has a big S on it so you can tell which "T" bar is which.
For tires I am not sure what the Tamiya stock tires are. I am simple and I like numbers so I use Kawahara tires. They come in different shore numbers so its easy to understand what tires I might need to use. I recomend that you ue whatever brand is easy to get for you that has shore rating and go from there. You also have to remember that as the tires go from big to small they start to feel different. Foam/sponge tires can be a pain, so some people do use rubber tires. No one i race with uses rubber tires but that doesnt mean you cant.
The TRG and Cross rubber tires are the same. Cross makes them for TRG and they are good tires. The only other rubbers tires I know of now are Ride these are good also. Tamiya used to make rubber tires but these are really old now so if you buy some from some where they will not be fresh rubber.
I know Lipo are nice but if you have an Nihm battery just try it once and see if you like how the car handles. Or if you dont add enough weight to equal a Nihm battery and try that. You might be happier with the car.
