I enjoyed building mine a lot more than running it. Bit disappointing even with both diffs locked. It's sort of halfway between a comp & scaler but doesn't excell at either, but like a said a real fun & complex build.
2nd that, TA01, great cars. Apart from bearings and an ESC I would replace the "coat hanger" drive shaft and motor mount if you plan to put in anything hotter than a sport tuned.
I would settle for something like a TT-02RA; long CVA's with frp towers, turnbuckles, ball races, lexan dustcover & foams for the chassis tub, rally blocks and a torque tuned motor. Priced the same as the drift spec cars would seal the deal.
Why not buy a cheep TA02 rolling chassis from eBay? There's normally one for sale between £20-£30. Have fun fixing it up, put on the rally body of your choice, run it as hard as you want- spares and hop-ups are cheap and readily available as it's still a current model. Ground clearance and suspension travel are respectable if you build it with long shocks and it's fairly capable off road, being based on the Manta Ray.
