Ok as some of you may know I aqired a xxt a few days ago. I finally finished this sucker up and now a problem has aqured that has me pullin my hair out. Ok so I soder all the deans and the new motor on so everything is good. Plug in the battery, and the speed controll dosent do anything when I grab the throttle. So theres a little set buton on the side, I push it and hit the throttle and boom it works, but I let it go and it dies! What gives? I can't figuar it out, and I'm really pissed now because I just put dean plugs on 2 brand new batteries, and bought a new set of tires , and a new motor. I'm so frigin steaming right now its not funny. Its a tenkin speed controller by the way. I dont have any more money for a speed controll and I really wasent planning on droping 100 bucks on a new one either. So is there any sugestions you guys could give me as to what I could do with the speed control, maby to get it reset or WORK! Or tell me if there is a cheap speed controll out there that wont break the bank and I mean cheap, just to get me around. Thanks for your help guys.

Oh and I'm also a little pissed because my colledge said to register tonight online, and now the website is down, so I may not get the classes I wanted to take. This is probally where the majority of the maddness if from tonight.
 
First of all, don't do anything else. It's been a while since I had ESCs, but I'm ordering one for a boat project now.
What I do remember is that there's a procedure to reset them, or center them to neutral as I recall. If it's brushless, it's a different process.
Just stay calm till someone throws the right info your way.

Best of luck getting your choice of classes.
 
For the Tekin, if memory serves correctly, turn on the radio gear (transmitter first, esc next). Now, with the trigger at neutral, press the setup button (light should be either blinking or solid green, I can't remember), then move the trigger to full brake (should go from green to red), then to full throttle (green solid), then neutral (don't remember if it's both green and red, or solid green...). At this point, the ESC should be re-calibrated.

Now, as for a "weak" drive. Check for binding in the drive train; the truck should roll VERY freely without the pinion gear on the motor. If it does, check your gear lash, and make sure you are able to rock the spur slightly. Just a HINT of slack, not much, is all you need.

If that does not cure it, it is possible the esc is fried.

edit; after re-reading the post; if you're push-starting the car (by the sounds of it), then you most likely have a motor that is defective/dead, or has a broken brush. Try resetting the speed controller by doing the above steps, and if that doesn't work... Try connecting the battery directly to the motor, and see if the motor spools up.

I thank you verry much for that heartbreak. I'm going to try to reset that sucker when I get home following your instructions. I'm just a little bummed that its is going to cost me more money to get this sucker running if it dosent work. I also am starting to think that the controller is jacked because the servos glitches everynow and then. I dont get it. I really want to get this sucker runing though. Just because its quiet and wont piss the neighbors off to bad. Once again thanks,

Look at it this way man; if you're not pissin _someone_ off, you're not doin it right.

If your servo is glitching every now and again, it's more likely you have a bad servo. I have one that twitches if I return it to center/neutral too fast. Turns out, Hitec's don't like to be mounted with the bottom of the servo touching a GS Storms' chassis.

But I digress; If the servo is indeed hosed, a standard servo will do more than fine in the XXT for just driving it around. I used to use a Hitec 525MG in my XXT (it's now in my RC10T3), and it worked fine.
 
If I get around to it lol, I'm going to just mount up a traxxas servo in it. I have like 10 of these things laying around so if they fry who cares. I havent tried reseting the speed controller yet, been bussy tring to figuar out what the hells going on with my revo. But eventually ill get around to it.

Ok little update. So the speed control was crap. I went down today, and told the guy at the hobby shop just give me something to get this thing rollin. He sold me a dynamite speed control, 30 bucks, no big. I get home, take it out of the box, only to find I need the conectons that go from the motor, to the speed controller wires. Right now with the old one its hard wired to the motor. I have torn my room apart, looked in the electrical crap in the garage, and I have no clue where these damn leats went to. I can't belive I would through them away. So now I got to go back down to the hobby shop to get the little leads, and they will brobally cost me a arm and a leg. This sucks. Its true, junk is something you through away 2 weeks before you need it!

Bryson

Also anyone know if there is something you can put on leads, like tyamia(spelling) conections, like that are on most battery chargers, to clean, and make the conection better. My deans adapter charger cable has problems with the conection from the charger conection, to the adapter wire conection. Thanks!
 
Grab some Deans Ultra connectors. They are far better than the white tamiya plugs, and won't melt together over time.
 
I know deans are better, but to wire straight up to a charger. Will that work? HUH. Never thought of that.
