The spektrum servos are not up to the job of controling a large scale car/truck. They probably would be fine in a Savage/Revo etc.
The spektrum tx does feel a bit toy like, but the trade off is worth it....

A friend of mine just bought one (dx-3) and it had bad servos out of the box. i think the spektrum concept is awesome, but the company that is marketing the technology at the moment needs to improve the quality control and not to dis, the dx-3 radio but it feels kind cheesy compared to some others out there. (no offence ppl, just an opinion.) im using an airtronics mx-3 with a failsafe, and mine is fine.
