CV setting for Coreless Motors

[BRGreenDieselPaul]

Hi

Can anyone recomend some appropriate CV settings when using a TTS decoder with a Coreless motor CV's 150 to 154 need to be tweaked I understand

Just put one in a graham Farish Duchess and slow speed is a little lumpy at its default settings

I have read the instructions but can't get my head around what needs changing and to what, I did find some on a forum once but now I need them I can't find the link any more  ☹️

Anyone know what the basic changes should be.

Thanks

If you have CV 150 at 0 then drop the value of 151 by a value of 5 until you have smooth running ,if the jerkiness is when stopping then increase / decrease 152 until you get smooth running .

Perhaps someone can enlighten me what a 'coreless' motor is.  I think I understand what a can motor is and I do know what a ringfield motor is.

Google 'coreless motors' and all will be revealed.

Wouldn’t a Farish Duchess be N gauge?

In which case how in hell did you fit a TTS decoder?

I've seen a TTS in an N gauge diesel so it should fit in a tender. Must be a small speaker though.

It goes in the Tender fine and the use of a 9mm sugar cube speaker makes a nice quality sound

I have them in 2 Farish Duchess's a Farish Merchant Navy and in the Diesel department I have them in Farish Class 31, 37 & 47 & in a Dapol 67.
