If both using the same Brushless system , One is plastic car and the other One is carring many many aluminium parts ,what do you think?! The Light one or Heavy one ??
TB-evo5 has a higher potential in term of playing high performance motor than Ta05R.
Ah C la Ta use it to play 4.0r without any problem and very fast time la!
BTW, metal + chassis, most of the time is lighter than plastic part.
