Diodes?

Its a matter of voltage. Lower it.

If they still chatter then gears may well already be damaged. If you wish send to us and we will look a them for you.

Thanks for your  reply but how is the best way to lower the voltage as all the others are fine its just one and one digtal one which do it i am using 12 volt suppy which I have checked which reads 12.04 amps  which supplys the whole layout which is all slow motors also feel some servos and lights so do I need to jus treduce power to just the ones that chatter ?

add diodes in series in one wire tp the motor. You will need 2 strings, one facing each way, in the same lead. Say 4 diodes in each string

Alternately send us the motor because if its only one then you may now have a chipped/damaged gear which we can replace for you.

Have  just got round to sorting this motor out and have removed said motor with the entition  of sending  it back torch con but trying  it out with a 9volt battery  and it works  fine  so will try  and fit diodes to lower the voltage what do you recommend?  many thanks in advance  Noel

Use standard diodes.
* Each will drop about 0.75 volts.
* Make two strings of however many diodes you need to drop the measured voltage to 9. 
(See the attachment)
*  Place alongside each other then Reverse/Flip one string of diodes 180 degrees.
* Connect the two strings together at the ends.
* Insert into one lead taking power to the motor..
