To be fair wor. The individual price really high? I think that is reasonable la.
For the labor fee, it is subjective.
And to be honest, they didn't ask you to buy many option parts....already with "leung sum" ga la.
If you really want to learn how to play RC car, put the TT01 aside (as invest on it seems not worth). Buy TB03 and assembly by yourself. You can enjoy more!
