ok i am having a small problem , i have a 7.2 v xxx-t when i am running it i can hear that the motor is getting power and then no power and then power and so on and so on BUT i never take my finger off the trigger ? i checked the antenna connection into the servo and that was fine ? made sure all my connections are fine . what else can i check ? it happends when the car is a little bit down the street ? maybe at like my neighbors house but i thought they would get a better range than that ? CAN ANYBODY HELP? THANKS IN ADVANCE !

are the motor and battery wires far enough away from the reciever/antenna? that'll shorten the range sometimes.

this is what im working with

is that electrical tape around the battery lead off the esc? sorry the photo's a little dark

this should be a kind of obvious question, don't be offended, but are the batteries in the radio good?

Is the chassis made of metal or plastic? The reason I ask is because it looks like the antenna wire is touching the frame. That could definitely be the problem if the frame/chassis is made of metal.

How far away are you going before it starts breaking up?

It's a xxx-t chassis so it's plastic. Look for frays in the wires. You should be able to get a couple hundred feet range, no problem. If it only happens when you are at a certain distance then you have a radio issue.

Are you running a brushed motor cause that looks like an LRP esc. If it's a brushed motor , take the motor out and clean the com, and brushes they probably
are just fouled up . You can get a com cleaner and clean the com and brushes with it if the com an brushes are in good shape.

yes it is tape around the esc battery wires someone before me had cut them for some reason ? maybe for a new connector?

the radio batteries read more that half on the display ?

the frame is plastic . it is getting about to the far side of my neighbors house .

Yes it is a brushed motor i will also have to look at that .


thanks guys

haha, yeah but how far is your neighbors house? just curious like roughly the distance in yards? Has the truck sat for a while, like over the winter (so months mabye)? how old is the radio gear (receiver specifically)?

well if im in my driveway where i usually am the neighbors is like 50 yards but my brothers will go much farther i have to turn around way before his or else i will have to walk closer to my car because the range is to far? not sure how long it sat i just bought it from someone else. the reecier looks old ? not sure though

First thing I would try is changing the radio batteries. Try using regular alkaline batteries. (if you aren't already)

Since everything else looks fine I'd then try soldering some new capacitors to the motor. I've had a few times where I was pulling my hair out trying to figure out why my radio was glitching and it was due to the lack of caps on the motor. The motor creates radio noise and the caps suppress it. I'm not sure what caps you'll need, usually the ESC manufacturer will recommend which ones to use. If not I'm sure somebody here can come up with what they've used.

you can find caps at tower hobbies. something like [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXBJ87&P=ML]this[/link] should work

I have this exact same problem with my first gen Traxxas Rustler electric. I've tried different motors, escs, it's always the same: my range is about half of what anyone elses is. I've tried putting the radio as far away from the wires as possible, and braiding or twisting the wires. No difference.

CAPS as im like battery caps? i have brand new batteries . in the controller i also have brand new batteries . i cant figure it out? ? ALSO WHEN I TURN THE CAR ON I HAVE TO USE THE TRIM EVERYTIME JUST TO MAKE IT NOT GO ON ITS OWN LIKE THE TRIM IS TO HIGH ONE WAY OR THE OTHER ? IS THAT NORMAL?
