So, took the spur gear off today and spun the motor by hand. A little resistance but easy to turn.
good start
turned the wheels with no spur so obvs no motor interference- all drivetrain. Again a little bit of resistance but hardly any.
still good.
pop spur gear back on entire drivetrain feels tight again.
it’s not like something is binding it just feels like there are brakes on a little or like you are acting against motor torque or something. Maybe it’s normal, but it feels like it wouldn’t really slowly descend on say a 30degree slope.
motor is a Holmes Crawlermaster sport 12t if that helps.
incidentally I have noticed the angles of the axles are a bit weird, front tipped down at the front and back ripped down at the rear. Is this normal? I have got the arrows lined up on the hub carriers but it looks a little odd.
cheers guys.
