Traxxas Radio Issues?
 

My traxxas stampede with the older model TQ receiver and transmitter has been acting really weird lately, sometimes I won't give it any throttle, and it will just start going full speed in a random direction, and I can't stop it. And other times it won't respond to the transmitter at all. A few months back, my antenna wire broke, so I soldered it back together, and my transmitters antenna isn't fully connected at one of the links, but other than that, it's fine.

Should I just buy a whole new radio system? Or just replace the antennas? Or the crystals? I really just can't drive it when it's acting like this.

Also, range isn't very far either, only 150-200ft, and there's lots of stuttering.

get this http://www.hobbypartz.com/79p-gt2-blue.html I have a few of their radios(I even have that model), and honestly they work great.
Remember seeing a video where someone wanted to find the range, and he gave up somewhere around half a mile lol. From experience I can say the range is farther then you can even see the RC as I've driven RC's over the horizon (I live where it is VERY flat)

The AM TQI's I've had I found to be pretty crappy I owned 2 both failed, and my nephew who has a pede's failed too. Your issue is probably crystal related, some strong interference, or even the controller failing (mine was due to the controller failing). This is the reason I just recommend that radio I linked as you will not have any crystals to fiddle with(and hell crystals could cost more then that radio), once bound the radio stays paired.


http://www.hobbypartz.com/79p-gt3b-carradio-lcd.html is another good radio(own one), but honestly all it has over the 1st one is an load of options you would never really need on a Stampede. If you owned multiple RC's (like I own 20+) then yes it pays to get as it can be setup to control 10 different RC's, and stores settings for each one so you don't have to fiddle with knobs.
