The 4.1 RTR is ok, good value as it comes with Reedy esc and 13.5t motor which is quite good especially indoors.... Downside is shocks, turnbuckles,servo etc but can be upgraded over time....if it is for your wife / son then itis a good starter.
Bought my grandsons RTR ,s then upgraded to factory team as and when parts and money became available..!
A better option is still a good second hand factory team at the right price..
As always it depends on disposable income !!
