Some photos of my attempts at improving Hornby green, the first picture shows Tamiya X-24 Clear Yellow airbrushed on to a spare A4 tender - 

And the second picture shows the same paint brushed on - 

The clear yellow was used as I felt the original green needed to be richer.

Both finishes seem to be acceptable.

Another experiment I have tried was using the Humbrol 1322 clear orange (yellow?) on a Hornby Duchess pictured below.

This has given a very good finish in my opinion BUT, and it is a big but --

too heavy and you'll destroy the paint finish below (the affected paint will bubble up, like you've hit it with paint stripper)

The Humbrol finish has a glossier look then the Tamiya which some may prefer but both do seem to enhance the original green.

Thanks for your response, I think I understand but at some point would like to see a diagram or photo of where exactly the resistors go. As an aside did you see the circuit printed in MRJ No 205? Would you have any comment.

Sorry, for us non electronic types who also use servos, can you please explain what a "pull up" resistor is or does and where it is fitted in the system. Also would it not be possible to ensure that the voltage (or current?) does not drop off by using a higher rated supply?

Thanks, and sorry if this is too basic for you electronic wizards!
