I have been using the IT4S for 1/10 offroad and onroad for over a year now, love the easy to use touch screen and menu, more features than you will ever use, have only had problems with the older smaller recievers, the ones that are 8 bucks, but I have since put a couple layers of servo tape to isolate the impact and vibration and they have been fine. Put a small piece of servo tape under where the wheel swings out to keep it from moving and your golden, great radio!
