Car runs slowly forwards

[matthewboyles]

Hi!
My RC electric car has started running slowly forwards! It runs faster backwards. I have two fully charged batteries and they both do the same thing. Now I think about it, it has been accelerating a little slowly uphill/offroad for a few days. Any advice? Do I need a new motor or can I rebuild it? Its a brushed motor.
Thanks!

would help if you posted what electronics, motor, transmitter etc you are using to get some meaning full advice

Hi, my transmitter is a digital radio control system NO:H734071. My motor is a brushed 540 one. My receiver has no sticker on it! What other info might you need? Its odd how this just started happening a few days ago. It was fine before!
Thanks a lot

Have changed any wires or anything around, motor could be running in reverse as when u go to go forward u are but with the reverse being forward if u know what I mean lol

Hi, It still works in the right direction, its just that it does not go very fast forwards! If its going down hill it does get speed up, but back up the hill it slows down again, like its not got enough 'torque' to go fast.
Thanks again!

does your radio have end point adjustments? can you post a picture or link of your transmitter?

[matthewboyles]

Yes it has three adjusters, one adjusts the steering left to right (ST Trim) set to 0, one seems to set it running backwards or forwards slowly if on anything other than 0 (TH Trim) and a third one is ST D/R which adjusts the range of the steering left to right, set to 5 out of 6.
Thanks!
