"在入彎時反方向轉呔其後馬上轉回車要入彎的方向" : This is a standard skill for rally drivers.
One can practise this in rally game similator, master it before apply to 'real' (r/c) cars.
That will avoide fry your car which may result a total loss :-)
But for TA03-R it would be a bit difficult as the gear chain design is like a dump-bell.(like TL01)
Therefore the momentum of the car is high and less willing to react to your steering input.
But then a quick (and powerful) servo (and strong servo saver) can help.
Also change the pastic stearing linkage into alumimun also can help.
But then putting so much money to hopup maybe wise to save it for your next (better) car.
