So far I have had no success in locating a supplier here. Any ideas chaps?

I guess because HL simply reverses the polarity for left and right turn, it depends on where (-neg or +pos) you put the resistors, you will get different turning speed.
Don't know enough about resistor to say if the wattage makes the difference as well, and also while the longer I run the motor the slower it gets.........
