ok I have a RDX and a Xray t2.
The rdx, fast out of the box (being uk spec) veryvery good outdoors.
Indoors is probably my driving, but i found the front steering knuckles to be very weak......yes i know the alloy ones would solve that but its a lot of cash. They were breaking with the slightest impact....rubbing a mate down the straight broke on...on harder inpacts they knuckle just vanished.
so bought a t2.
havent run it properly yes, but you can tell the plastic used is of better quality, no upgrades required.
Will run the car in the next few weeks.
