Default slowing stampede

Hey guys, I am new to rc. I just bought a stampede about 3 weeks ago. I used a 6 cell battery and an old charger that a friend gave me for the first 2 weeks. The Truck suprised me with how fast it was. Then I bought a 7 cell and it was even faster. I also bought a triton jr charger. Well gradually the last few times I ran it, it is a dog compared to what it was. I have only run it maybe 5 battery charges. Could I have a bad battery? Could I have damaged the motor? It basically runs like the battery is not fully charged. Any suggestions?
Thanks,
Ant

What motor is in it? It may need to be cut if it is a brushed motor. Has anything gotten hot?

Its the stock 550 motor. It does get hot to the touch but i havent done anything outrageous with it. And it was not run much. Could i have damaged the motor that fast?

you might have, thats why i dont like their motors. get it cut and replace brushes. if you just bought a 7cell pack it can go bad that fast unless you put the wrong stuff in it like putting nicd in nimh.

The stock 12t Titan motors cant easily be opened up to have the Com cut or the brushes replaced. You can find new titans on Ebay real cheap, or put some of that $$ into a motor you can maintain. My rustlers titan went quick. I replaced it with a Trinity Speedgems 15t and that went even quicker, then I just said screw it and got a mamba w/ 5700 motor. I swore off brushed motors untill recently when I got a road car with a brushed setup. Now I think I have enough experience to stay on top of maintenance and it may last a while now....

Is there anyway to check if its the motor? Would a bad motor cause it to gradually slow down like that? Also I ran it through grass that made it bog down last week, for about 5 or 6 minutes. Could that have down it?

The stock titan motors are not that great to begin with and will be amazed how much performance a rebuildable motor has compared to a titan motor . You can pick up a descent machine wound modified motor [like Trinity Speed Gems] for a good price . I would just go and get a new motor just because the fact titans tend to fail and you cant rebuild them .

Trying cleaning the motor out as well. The Titan has a fan on the end of the rotor and it tends to attract a lost of dust to the commuter that can rob performance.

Yes, running through thick grass can overheat your motor in only a few minutes, not to mention your slipper. Titan motors are indeed disposable, not rebuildable but a good shot of motor spray may clean it up enough for a couple more runs. You'll be amazed at the power of any $30 or higher rebuildable motor when it's fresh but it will require maintenenace. The cheaper motors aren't worth buying IMO you might as well buy another Titan.

You didn't say what batteries you were using. If you are using Nicad's, then that is probably your problem.
If it is a DOG compared to what it used to be. The motor is pretty stout and would probably take more than 5 packs to damage it.

Hey, i also have a pede!
I found in some forum that running 7 cell can easily ruin the com of titan motor.

in the past i used to clean my titan by soaking it in the water. I used 2 cell or 3 volts batts to run the motor under the water. Do not use the ESC to power the motor under water, it might damage your ESC. After a few changes in water, i let it dry. After that i put some motor oil (i forgot the name, it was a bushing and bearing lubricant). I used this method to clean NON-rebuildable motors.

Today i am using Epic outlaw 27T. This motor is reeeaaally fast

Please dont use the above method to clean rebuildable motors

Why would you say it would be the batts if they were nicads ? Nicads kicked ass back in the day before Nimh came out .

why didn't anyone ask if he's running stick sport pack or racing pack. the batteries in the sport pack could be unequal too.

A sport pack versus race pack won`t make much difference when bashing or backyard playing , especially with the batteries these days you really don`t even have to worry about run time . Back when we had Nicads it was a different issue . A matched racing pack only shows much difference in punch and run time when racing . Many race packs have unequal cells also if the proper maintenance isn`t taken care of .
