The Standard TT01 for whatever reason doesnt come with what would be
the most basic of parts: bearings & metal centre-driveshaft.
Everything is a 'hopup', that has to be bought separately, making the car alot more expensive than it needs to be....
Its not unheard of for the hopups to double the actual total price of the car.

The TT01 is a reasonable car, just way overpriced for what it is....

The TT01D (D for Drift) at least has good drift tyres & wheel bearings.
Also look at the TB03D, or TA05:much better cars.
