Trex jr motor 2 output

Support Motor controllers/drivers and motors

I have a TRex Jr. hooked up for RC with two micro metal gear motors 150 to 1.
Motor M2 always seems to run faster and start first making my car pull right.
I changed the leads (M1 to M2 and M2 to M1) to see if it was the motors, no change.
Then i set it up to run serial ,no change.

I’m asking if you guys or gals could maybe tell me why this is and what the fix might be

Thanks in advance

Hello.

It sounds like you are saying that the one motor channel is always slower than the other despite swapping the motors, is that the case?

yes
I did later swap the motors and it seems not to pull to the right as much

Hello.

Have you calibrated the channel on the TReX Jr? If you have not and are not sure how to calibrate the channels, you can find instructions for calibration in the TReX Jr user’s guide.

OK I did this some time ago I’ll recalibrate and see what happens.
I think it is the motor
The funny thing about it is one of the motors runs fine in one direction but when reversed
runs slower
So now that I have swapped motors it runs fine forward and pull of to the left in reverse
Thanks for your help
